The fish

Pacific halibut (Hippoglossus stenolepis) are large flatfish found on the continental shelf from California to the Bering Sea. Halibut have flat, diamond-shaped bodies, can weigh up to 500 pounds, and can grow to eight feet long. The oldest halibut on record, both male and female, is 55 years old.  The stock status of these fish is tracked by the International Pacific Halibut Commission (IPHC), which reports on the status every year at its annual meeting, and provides detailed life history information on their webpage.

REPRODUCTION

Female halibut mature at around 12 years, while males mature at around 8 years. Adult fish tend to remain in the same area year after year, except for their migration to spawning grounds. Adult halibut will migrate long distances from shallow summer feeding grounds to deeper winter spawning grounds. The number of eggs they lay depends on the female’s size. A 50-pound female can produce about 500,000 eggs, while a female over 250 pounds can produce four million eggs. The eggs float freely and drift in deep ocean currents and are fertilized externally. The eggs hatch 12-15 days after fertilization, and the larvae drift to shallow waters on the continental shelf. Larvae begin life in an upright position with eyes on both sides of their head. When they are about an inch long, the left eye migrates over the snout to the right side of the head, and the color of the left side fades. When the young fish are about six months old, they settle to the sea floor, where the protective coloring on their “eyed” side effectively camouflages them.  

PREY AND FEEDING

Larval halibut feed on zooplankton, while juvenile and adults prey on cod, pollock, sablefish, rockfish, turbot, sculpins, other flatfish, sand lance, herring, octopus, crabs, clams, and occasionally smaller halibut. Adult halibut are sometimes eaten by marine mammals and sharks, but are rarely preyed upon by other fish.

Halibut management schedule

Halibut have been fished for hundreds of years by native Americans on the west coast of the U.S. The U.S. commercial fishery started in 1888, when halibut were first landed in Tacoma, Washington.

Because halibut can be kept for long periods of time without spoiling, they soon became a popular target for commercial harvesters. In the 1890s, a fleet of sailing vessels with two-man dories fished for halibut from the west coast. Large steam-powered vessels soon entered the industry, and by the 1910s it became clear that halibut stocks were suffering from overfishing. In 1923 the U.S. and Canada signed a convention on halibut, creating what was eventually called the International Pacific Halibut Commission. In 1924 the Commission implemented a three-month winter closure – the first management action to affect halibut. The convention was revised several times over the years to allow the Commission to meet new conditions in the fishery. The most recent change occurred in the Protocol of 1979, which allowed each government to establish more restrictive regulations. Canada implemented a limited entry system at that time and an individual vessel quota system in 1991.  In the U.S., Alaska implemented an individual fishing quota system in 1995, similar to the individual vessel quota program in Canada except that shares were issued to individuals instead of vessels. Also in 1995, non-tribal commercial fishers in Oregon, Washington, and California had to make a choice: participate in the sport charter industry for halibut, the commercial directed fishery, or the halibut incidental fishery in the salmon troll fishery.

Each year the IPHC conducts a stock assessment to estimate the abundance and trends of the Pacific halibut stock using commercial fishery data and scientific surveys. The Commission utilizes a decision table to report the results of the annual stock assessment, effectively separating the science from policy.  The decision table, prepared annually by IPHC staff, presents the Commissioners with a range of coastwide harvest levels, each with accompanying estimates of potential risk in terms of stock and fishery trend and status metrics.  The Commissioners consider the coastwide assessment, and the current harvest policy in determining the final catch targets for each year.  

Total catch is set by the IPHC, and the Council then allocates that total among Area 2A fisheries (treaty Indian, commercial non-tribal, and recreational). For more information on how IPHC sets halibut catch limits, see the IPHC document “How are Halibut Catch Limits Determined?” To learn more on how harvest is divided off the west coast (Area 2A), see the Halibut Catch Sharing Plan described below and found under ‘Key Documents’.

The Fishery and Gear

The commercial halibut fishery on the West Coast was pioneered by fishers of Norwegian ancestry, many of whom had fished halibut in Norway. Many Nova Scotians and Newfoundlanders have also participated in the West Coast halibut fishery.

Halibut are one of the most valuable fish species in the northern Pacific. Pacific halibut fishing is an important part of several tribal cultures, and many tribal members participate in commercial, ceremonial and subsistence fisheries. Longlining is the main commercial gear used to target halibut, although there is some allowance for incidental catch in the commercial salmon troll and the primary sablefish fisheries. Vessel, trip and landing limits are all used to manage halibut harvest in non-tribal commercial fisheries.

Halibut is also a very popular target for sport fishers in Washington, Oregon, and California.  Because halibut fishing is so popular, managers use closed seasons, bag limits, and possession limits to extend the halibut sport season as long as possible.

In 1995, the U.S. prohibited directed non-tribal commercial fishing north of Pt. Chehalis, Washington in order to allow the tribes to harvest their allocation of halibut.

Halibut Catch Sharing Plan

The Halibut Catch-Sharing Plan is a framework that dictates how the IPHC and NMFS will divide the total allowable catch (TAC) for Oregon, Washington, and California halibut fisheries (Area 2A). The total TAC is set each January by the IPHC, who also endorses the Catch Sharing Plan allocations set by the Council. Allocations between some recreational areas are subject to inseason and other changes. For a description of how the halibut harvest is shared, see the halibut catch sharing plan under “key documents” on this page.

Each year the Council solicits proposed changes to the Catch Sharing Plan for its September meeting and takes comments on proposed changes between its September and November meetings. The Council then makes final recommendations for changes at its November meeting. The proposed changes are described in the Council Newsletter and in the annual September decision document. If you would like to propose a change or comment on proposed changes, you can submit comments by mail, fax, or email, marked to the attention of Robin Ehlke, Pacific halibut staff officer.

Fact Sheet: Coastal pelagic species

The fish

Coastal pelagic species (CPS) are schooling fish that range from the shore to the open ocean. They are found near the surface or as deep as 1,000 meters. They are generally small, even as adults, ranging from about four inches (anchovies) to 24 inches (Pacific mackerel). CPS are sold for human consumption, bait for longline fishing, and feed for tuna aquaculture.

The Council’s CPS Fishery Management Plan (FMP) specifies a management framework for northern anchovy, market squid, Pacific sardine, Pacific mackerel, and jack mackerel. The plan prohibits harvest of all krill species in order to protect krill’s vital role in the marine ecosystem. Pacific herring and jacksmelt are included as ecosystem component species, which are not generally targeted, but whose stock landings and status are monitored.

Pacific sardine (Sardinops sagax) are small schooling fish. At times, they have been the most abundant fish species in the California current, the highly productive current that extends from Oregon to Baja California. When the population of Pacific sardine is large, it is abundant from the tip of Baja California to southeastern Alaska and throughout the Gulf of California. In the north, sardines tend to appear seasonally.

Sardines form three sub-populations. The northern subpopulation is most important to U.S. commercial fisheries, ranging from southeast Alaska to the northern portion of the Baja Peninsula. The southern subpopulation ranges from the southern Baja Peninsula to southern California, and the third population is in the Gulf of California.

Sardines may live as long as 13 years, but most landed fish are three to six years old. Like anchovies, they are taken by a wide variety of predators. For information on current Pacific sardine abundance and population trends, see the CPS Stock Assessment and Fishery Evaluation report (tinyurl.com/yc6smlog).

Pacific (chub) mackerel (Scomber japonicus) range from Mexico to southeastern Alaska. The “northeastern Pacific” stock of Pacific mackerel is harvested by fishers in the U.S. and Mexico. Mackerel are schooling fish, and they often school with other pelagic species such as jack mackerel and sardines. While young, they are heavily preyed upon by a variety of fish, mammals, and sea birds. But when larger, they can prey on smaller fish such as juvenile hake and other CPS.

Northern anchovy (Engraulis mordax) are small, short-lived fish that are typically found in schools near the surface. They are found from British Columbia to Baja California. Northern anchovies are divided into northern, central, and southern sub-populations. The central subpopulation ranges approximately from the Oregon/California border to Point Descanso, Mexico. The northern subpopulation ranges from the Oregon/California border north to British Columbia and sometimes SE Alaska. Northern anchovy are an important part of the food chain for other species, including other fish, birds, and marine mammals.

Jack mackerel (Trachurus symmetricus) are a schooling fish that range widely throughout the northeastern Pacific. They grow to about 60 cm and can live 35 years or longer. Much of their range lies outside Federal waters (more than 200 miles offshore). Small jack mackerel (up to six years of age) are most abundant in the Southern California Bight. Older, larger fish range from Cabo San Lucas to the Gulf of Alaska, where they are generally found offshore in deep water and along the coastline to the north of Point Conception.

In southern California waters, jack mackerel schools are often found over rocky banks, artificial reefs, and shallow rocky coastal areas. The peak spawning season for jack mackerel off California extends from March to July.

Market squid (Doryteuthis opalescens) appear from the southern tip of Baja California to southeastern Alaska. They are most abundant between Punta Eugenio, Baja California and Monterey Bay, California. They are harvested near the surface, but they can appear to depths of 800 meters or more. They prefer the salinity of the ocean and are rarely found in estuaries, bays, or river mouths. Squid are short-lived (up to ten months) and are important as forage foods to many fish, birds, and mammals, such as Chinook salmon, coho salmon, lingcod, rockfish, seals and sea lions, sea otters, porpoises, cormorants, and murres. Market squid have huge population fluctuations, sometimes appearing in great numbers and sometimes seeming to disappear almost completely. They are the most valuable CPS stock on the West Coast and are highly sought after.

Fishing boats at dock

The fishery and gear

In the 1940s and 1950s, about 200 vessels participated in the Pacific sardine fishery. Some of these boats are still fishing today, but the fleet is much smaller, with less than 60 Federal limited entry permit vessels.

CPS species are harvested directly and as bycatch in other fisheries. Generally, they are targeted with “round-haul” gear including purse seines, drum seines, lampara nets, and dip nets. These species are also taken incidentally with midwater trawls, pelagic trawls, gillnets, trammel nets, trolls, pots, hook-and-line, jigs, and beach seines.

Market squid are fished at night with the use of powerful lights, which attract the squid to the surface. They are either pumped directly from the sea into the hold of the boat, or caught with an encircling net. CPS species are caught primarily with purse seine vessels. A small amount is landed by beach seine and by hook and line.

Processors and buyers of CPS on the West Coast are located mostly in southern and central California, near the Columbia River port areas of Oregon and Washington, and in Grays Harbor, Washington. Most of the market squid and Pacific sardines caught in the U.S. are exported. Market squid are mainly exported to China, Japan, the United Kingdom, and Spain. Sardines are mainly exported to Japan, where they are used for human consumption and as bait for longline fisheries; and Australia, where they are used to feed farmed bluefin tuna. A small amount of sardines are sold to the restaurant market. Mackerel are exported to Europe and Asia for human consumption.

Management cycle

Pacific sardine and Pacific mackerel are “actively managed,” meaning they have biologically significant levels of catch, or biological or socioeconomic considerations requiring relatively intense harvest management procedures. Management measures are adopted annually. The three other CPS species are “monitored” stocks, meaning fisheries do not require intensive harvest management. They are assessed periodically, and harvest management is not changed on a regular basis. Stocks can be moved from “actively managed” to “monitored” or vice versa. Both active and monitored stocks are required to have annual harvest specifications including overfishing limits, acceptable biological catches, and annual catch limits.

Management measures, including annual harvest levels, are set for monitored stocks and are only updated as the need arises. The fishing year for monitored stocks is January 1-December 31.

The market squid fishery is state managed and largely concentrated in California, with an April 1-March 31 season. However, the stock occasionally extends into Pacific northwest waters in harvestable numbers.

The fishing year for sardines and mackerel is from July 1 through June 30 of the following year. The NOAA Southwest Fisheries Science Center (SWFSC) assesses the sardine stock annually, with management measures set at the April Council, ahead of the July 1 start of the fishing year. The SWFSC assesses Pacific mackerel every other year, and the Council sets annual management measures in odd years at each June meeting, for two years in a row.

Plan history and amendments

The CPS fishery management plan went into effect in 1999. Amendments addressing bycatch and tribal fishing rights, maximum fleet capacity, transfer of limited entry permits, maximum sustained yield for market squid, and allocation were adopted in the years following.

Amendment 12 (2006) banned commercial fishing for all species of krill in Federal waters off the west coast. State laws prohibit krill landings by state-licensed fishing vessels into California, Oregon, and Washington.

Amendment 13 established several new fishery management provisions pertaining to the Magnuson-Stevens Act, introducing overfishing levels, annual catch limits, annual catch targets, and accountability measures. Pacific herring and jacksmelt were also added to the FMP as ecosystem component species.

Amendment 14 established an maximum sustainable yield value for the northern subpopulation of northern anchovy.

Amendment 15 (2015) added a suite of lower trophic level species to the FMP’s list of ecosystem component species. It prohibits development of commercial fisheries for the  ecosystem component species shared between all four FMPs until and unless the Council has assessed the scientific information relating to any proposed fishery and considered potential impacts to existing fisheries, fishing communities, and the ecosystem.

Amendment 16 (2018) allows for small-scale commercial fishing on CPS finfish to continue when the primary commercial fishery is otherwise closed. This sector accounts for a very small portion of the overall catch of any particular CPS stock, and has a negligible impact. However, it is an important source of income for some small ports and producers, especially when the directed fishery is closed. The amendment includes a maximum of one ton per vessel per day, with a one-trip-per-day limit.

Amendment 17 (2018) modifies the landing requirements for the live bait fishing sector when stocks are overfished. Before, once a CPS stock became overfished, landings would be automatically restricted to a pre-determined 15 percent incidental catch limit, with no directed fishing allowed.  Amendment 17 requires the Council to consider management measures and landing limits at the time a stock is declared overfished.

Fact Sheet: Highly migratory species

“Highly migratory species” (HMS) include tuna, some shark species, and billfish—species that range widely through the ocean, often crossing international borders. These pelagic species live in the water of the open ocean, although they may spend part of their life cycle in nearshore waters.

HMS are harvested by U.S. commercial and recreational fishers and by foreign fishing fleets. For most Council-managed HMS stocks. only a small fraction of the total harvest is taken within U.S. waters.

The following species are managed under the Council’s highly migratory species fishery management plan:

  • Tunas: north Pacific albacore, yellowfin, bigeye, skipjack, and Pacific bluefin
  • Sharks: common thresher, shortfin mako, blue
  • Billfish/swordfish: striped marlin, Pacific swordfish
  • Other: dorado (also known as dolphinfish and mahi-mahi)

Some species (such as pelagic thresher and bigeye thresher) are monitored for informational purposes. Others, including great white sharks, megamouth sharks, basking sharks, Pacific halibut, and Pacific salmon, are prohibited. These species must be released immediate by anyone accidentally catching them while targeting other species.

The fishery and gear

Several gear types are used to catch highly migratory species:

Vessels with troll gear and bait boats target albacore tuna off the west coast. On troll vessels, fishing lines are rigged to outriggers (trolling poles), which are deployed at about a 45 degree angle from the sea surface. Albacore are usually harvested by trollers with jigs or live bait. Bait boats release live bait into the water to encourage feeding and then use pole and line to catch the albacore.

A drift gillnet is a panel of netting suspended vertically in the water by floats, with weights along the bottom. Fish are entangled in the net. Drift gillnet gear is anchored to a vessel and drifts along with the current. It is usually used to target swordfish and common thresher shark. Drift gillnets are currently used off California.

Deep-set buoy gear is currently being tested with exempted fishing permits. This gear includes “standard buoy gear” and “linked buoy gear.” This type of gear could supplement other gears used to target swordfish.

Coastal purse seine. A purse seine is an encircling net that is closed by means of a purse line threaded through rings on the bottom of the net. This gear is effective in catching schooled tunas. “Coastal” purse seiners are smaller vessels that fish close to the California shore. They mainly harvest coastal pelagic species (sardines, anchovies, mackerel), but they also fish for bluefin and other tunas when they are available.

Large purse seine. Large purse seine gear is used in major fisheries in the eastern tropical Pacific and the central and western Pacific. This fishery is monitored and managed by the Inter-American Tropical Tuna Commission (IATTC), the Western and Central Pacific Fisheries Commission (WCPFC), and the National Marine Fisheries Service (NMFS). There are about 40 U.S. large-scale tuna purse seiners on the IATTC and WCPFC vessel registries.

Swordfish are also caught with harpoons (by only a few West Coast fishermen) and pelagic longliners (only Hawaii- permitted vessels). Pelagic longliners also target bigeye and yelloweye tuna.

Recreational fisheries. Recreational fisheries for HMS consist of private vessels and charter vessels using hook-and-line gear. In California, both private boats and a larger charterboat fleet fish for tunas, dorado, billfish, and sharks. Albacore tuna are a seasonally important recreational target off of Oregon and Washington. Charter vessels, mainly from San Diego, also fish in Mexico’s waters under license.

HMS management schedule

Domestic management of HMS fisheries

Any commercial vessel landing HMS on the West Coast must obtain a Federal permit from NMFS. Both commercial and recreational charter boat harvesters of HMS species must keep logbooks documenting their catch. Some are required to carry fishery observers. These measures are intended to improve data about HMS catches.

Each year, the Highly Migratory Species Management Team prepares a Stock Assessment and Fishery Evaluation Report that provides information on the status of HMS stocks and fisheries.

International management

Since HMS stocks move throughout large areas of the Pacific and are fished by many nations and gear types, management by the U.S. alone is not enough to ensure that harvests are sustainable.

The U.S. is a member of the IATTC, which is responsible for the conservation and management of fisheries for tunas and other species taken by tuna-fishing vessels in the eastern Pacific Ocean. The U.S. is also a member of the WCPFC, which plays a parallel role in the western and central Pacific (generally, west of 150° W. Longitude).

The fishery management plan provides a mechanism to meet U.S. responsibilities under the United Nations Agreement on the Conservation and Management of Straddling Fish Stocks and Highly Migratory Fish Stocks. The U.S. is also a member of the Food and Agriculture Organization of the United Nations, which has developed a Code of Conduct for Responsible Fisheries. As such, the U.S. is required to comply with international measures to reduce incidental catch of seabirds in longline fisheries, to conserve and manage sharks, to manage fishing capacity, and to prevent, deter, and eliminate illegal, unreported, and unregulated fishing. In turn, the U.S. has developed national plans of action to meet these requirements.

Management issues

West Coast swordfish fishery. The Council has outlined goals and objectives to reduce finfish bycatch and incidental take of protected species in fisheries targeting swordfish off the West Coast. (Protected species affected by swordfish fisheries include some species of sea turtles, marine mammals, and seabirds.) While reducing these impacts, the Council wants to sustain an economically healthy fishery that can supply locally-caught fish. Measures to reduce bycatch in the California large-mesh drift gillnet fishery have been a focus of Council actions, but the Council also wants to encourage the use of other gear types with lower bycatch. Council measures include creating a Federal limited entry permit for this fishery. Furthermore, the California state assembly has passed legislation to phase out the fishery.

Vessels fishing out of Hawaii, under the Western Pacific Fishery Management Council’s Pelagic Species FMP, deliver more swordfish to the West Coast than other West Coast-based fisheries. Hawaii longliners operate under a regulatory framework mandating gear modifications and operating procedures to reduce the take of sea turtles when targeting swordfish. If a similar framework were implemented for West Coast vessels, Pacific Council-managed fisheries could target swordfish with this gear.

Overfishing. Special requirements in the Magnuson-Stevens Act (MSA) are triggered when an internationally-managed stock is subject to overfishing or is designated as overfished. Consistent with the MSA, the Council responds by proposing measures to end overfishing and rebuild these stocks. Any response is complicated by the wide-ranging nature of the fish and the many nations, states, and regions involved. Effective management requires a great deal of cooperation among these entities. Therefore, the U.S. cannot rebuild HMS stocks alone. If the U.S. acts alone, U.S. harvesters could be penalized by having to comply with rules that other nations do not adhere to, and there would be little or no benefit to the fish stocks. Thus, the Council response focuses on ongoing interactions with international bodies (regional fishery management organizations) to develop cooperative ways to rebuild overfished stocks.

Sharks. Sharks are especially vulnerable to overfishing because of their biology and life history. The West Coast states have taken measures to protect sharks. A Federal law prohibits “shark finning,” where the fins are removed and the carcass is discarded. Including pelagic shark species in the FMP enables catches to be monitored and managed. The FMP also designates great white, megamouth, and basking sharks as prohibited species, meaning if these species are caught they may not be retained. This discourages intentional catch and, in cases where the shark survives the interaction, reduces fishing mortality.

Incomplete data. Improved data collection is needed in order to effectively manage highly migratory species, both in the commercial and recreational fisheries. The FMP includes provisions to increase and improve monitoring and reporting in HMS fisheries.

Fact Sheet: Common terms used in salmon management

Acceptable biological catch (ABC). A scientific calculation of the sustainable harvest level of a fishery, used to set the upper limit of the annual total allowable catch.

Accountability measure (AM). A management control (such as a harvest limit) designed to prevent annual catch limits from being exceeded.

Anadromous. Fish that spend their adult life in the sea, but swim upriver to freshwater spawning grounds in order to reproduce.

Annual catch limit (ACL).  ACLs are a cornerstone of the reauthorized Magnuson-Stevens Act of 2006. ACLs are vaguely defined in the Act as the calculated catch yield that cannot be exceeded for a particular species. Fisheries managers use the best available science to calculate the value of ACLs and seasonal limits.

Biological opinion (BO, BiOp). A scientific assessment issued by the National Marine Fisheries Service or U.S. Fish and Wildlife Service, as required by the Endangered Species Act for listed species. Determines the likelihood of an action to jeopardize the existence of a species listed under the Endangered Species Act.

Bycatch. Fish that are unintentionally captured in a fishery, but that are discarded (returned to the sea) rather than being sold, kept for personal use, or donated to a charitable organization. Bycatch plus landed catch equals the total catch, or total estimated fishing mortality.

Central Valley Index (CVI). A measure of the number of salmon produced by California’s Central Valley rivers, this is the sum of annual ocean fishery landings south of Point Arena, plus the spawning escapement of adult Central Valley stocks in the same year.

Coded-wire tag (CWT). A small piece of stainless steel wire that is injected into the snout of a hatchery-produced juvenile salmon or steelhead. Each tag is etched with a binary code that identifies its release group.

Conservation objective. Sometimes called the spawning escapement goal: the number of salmon needed to return to spawn in order to maintain the health of the stock.

de minimis. A restrictive harvest policy designed to minimize risks to stocks of concern while allowing minimal incidental impacts in fisheries targeting healthy and harvestable stocks.

Escapement. The number or proportion of fish surviving (escaping from) a given fishery at the end of the fishing season and reaching the spawning grounds.

Escapement goal. Same as “conservation objective” (see above).

Evolutionarily significant unit (ESU). A distinctive group of Pacific salmon, steelhead, or sea‐run cutthroat trout that is uniquely adapted to a particular area or environment and cannot be replaced.

Fishery management council. A fisheries management body established by the 1976 Magnuson‐Stevens Fishery Conservation and Management Act to manage fishery resources in designated regions of the United States. There are eight regional Councils, including the Pacific Council.

FRAM. The Fishery Regulation Assessment Model, a model used in setting salmon harvest levels.

Klamath Management Zone (KMZ). The ocean zone between Humbug Mountain, Oregon, and Horse Mountain, California, where management emphasis is on Klamath River fall Chinook.

Management objective. An annual goal for spawning escapement, or a harvest rate, that may differ from the conservation objective.

Maximum sustainable yield (MSY). An estimate of the largest average annual catch or yield that can be continuously taken over a long period from a stock under prevailing ecological and environmental conditions. In Council management of naturally-spawning salmon stocks, MSY is usually approached as the number of adult spawners associated with this goal (Smsy).

National Marine Fisheries Service (NMFS). A division of the U.S. Department of Commerce, National Ocean and Atmospheric Administration. NMFS is responsible for conservation and management of offshore fisheries. The NMFS Regional Director is a voting member of the Council.

Optimum yield (OY). The amount of fish that will provide the greatest overall benefit to the Nation, particularly with respect to food production and recreational opportunities, and taking into account the protection of marine ecosystems. The OY is developed on the basis of the Maximum Sustained Yield from the fishery, taking into account relevant economic, social, and ecological factors.

Pacific States Marine Fisheries Commission (PSMFC). The PSMFC is a non‐regulatory agency that serves Alaska, California, Idaho, Oregon, and Washington. PSMFC (headquartered in Portland) administers salmon disaster relief funds, provides a communication exchange between the Pacific Fishery Management Council and the North Pacific Fishery Management Council, and provides information in the form of data services for various fisheries.

Preseason reports. Prior to the development of management options for the salmon season, the Council’s Salmon Technical Team develops four preseason reports: Review of Ocean Salmon Fisheries tallies catch and escapement from the most recent fishing season. Preseason I, Stock Abundance Analysis for [Year] Ocean Salmon Fisheries provides forecasts for stock abundance for the coming season. Preseason II, Analysis of Proposed Regulatory Options for [Year] Ocean Salmon Fisheries analyzes proposed regulatory options for the year’s ocean salmon fisheries. Preseason III, Analysis of Council Adopted Management Measures for [Year] Ocean Salmon Fisheries analyzes management measures adopted by the Council.

Rebuilding. The process of rebuilding an overfished stock. For salmon, rebuilding usually takes the form of reduced harvest limits.

Sacramento River fall Chinook (SRFC). Sacramento River fall Chinook are historically a significant stock in West Coast commercial and recreational fisheries.

Salmon Advisory Subpanel (SAS). A Council advisory body made up of commercial fishery, recreational fishery, tribal, and conservation representatives. These advisors play a large role in developing the Council’s annual salmon management options in March and April. SAS meetings are open to the public.

Salmon Technical Team (STT). The Salmon Technical Team helps the Council by summarizing data from the previous season, estimating the number of salmon in the coming season, and analyzing the effects of the Council’s recommendations and amendments. The STT is made up of scientists drawn from state, Federal, and tribal fisheries management agencies, all of whom have technical expertise in salmon management. STT meetings are open to the public.

Scientific and Statistical Committee (SSC). A Council advisory body made up of scientists with biological and economic expertise. The SSC gathers and analyzes statistical, biological, ecological, economic, social, and other scientific information that is relevant to the management of Council fisheries.

Southern Oregon/Northern California coho (SONCC). SONCC coho salmon are found from Cape Blanco, OR south to the Mattole River, just north of Punta Gorda, CA.  The Rogue and Klamath rivers support the two largest components of the stock complex.  SONCC coho are listed under the Endangered Species Act as threatened.  

Southern Resident killer whales (SRKW). A population of killer whales listed under the Endangered Species Act. The Council is required to consider the effects of Council-managed salmon fisheries on Southern Resident killer whales when setting salmon seasons.

Spawning. The production and depositing of eggs by salmon or other fish. For salmon, spawning occurs in rivers and tributaries meeting certain healthy environmental conditions.

Status determination criteria (SDC). Criteria (such as target and minimum escapement levels) which allow the Council to monitor a stock to determine annually, if possible, whether overfishing is occurring and whether the stock is overfished.

Tule Chinook. Columbia River fall Chinook exist in two basic forms: “brights” and “tules.” Brights enter the river first, mature slowly, and retain their silvery oceanic coloration well into the freshwater migration. Tules are later-timed, are sexually mature upon freshwater entry, and spawn in lower mainstem and tributary areas, primarily below the Dalles Dam.

Salmon species

The Council manages Chinook and coho salmon. In odd-numbered years, the Council may manage pink salmon near the Canadian border. Sockeye, chum, and steelhead are rarely caught in the Council’s ocean fisheries.

Chinook salmon (Oncorhynchus tshawytscha) (“king” or “tyee”) are the largest and most highly prized of the Pacific salmon. Like all salmon, Chinook are anadromous, which means they hatch in freshwater streams and rivers, migrate to the ocean for feeding and growth, and return to their natal waters to spawn. Chinook salmon can live up to seven years. They return to their natal waters after 1-5 years in the ocean.

Chinook from Washington, Oregon, and California range widely throughout the Pacific Ocean and the Bering Sea, and as far south as the U.S. border with Mexico.

Some wild Chinook populations have disappeared from areas where they once flourished, and several “evolutionarily significant units” (distinct populations) have been listed as at risk for extinction under the Endangered Species Act.

Coho or “silver” salmon (Oncorhynchus kisutch) are found in streams and rivers throughout much of the Pacific Rim. Coho have a life history similar to Chinook. Coho in Council-managed waters typically spend only one year in the ocean. North of central British Columbia, they tend to spend two years in the ocean.

Coho generally use smaller streams and tributaries than Chinook. They are most abundant in coastal areas from central Oregon to southeast Alaska. Like Chinook, Some wild coho populations have disappeared from areas where they once flourished, and several populations are listed as at risk for extinction under the Endangered Species Act.

Management

Because salmon migrate so far in the ocean, managing ocean salmon fisheries is extremely complex.

Salmon are affected by many factors in the ocean and on land, including ocean and climate conditions, dams, habitat loss, urbanization, agricultural and logging practices, water diversion, and predators (other fish, birds, marine mammals, and humans).

Several different regions and groups are involved in the salmon fishery:

Recreational  fisheries take place in the ocean, Puget Sound, the Strait of Juan de Fuca, coastal bays, and in freshwater (including Columbia River Buoy 10). The Council manages recreational catches in the ocean but works closely with states on management in other areas.

Commercial  fisheries include treaty tribal and non-tribal ocean troll and various treaty tribal and non-tribal net fisheries in Puget Sound, Washington coastal bays, and the lower and mid-Columbia River. The tribes manage tribal fisheries in coordination with the Council. The Council manages fisheries in Federal (ocean) waters, but works closely with states and tribes on fisheries in other areas.

Tribal Ceremonial and Subsistence fisheries occur in Puget Sound, Washington coastal rivers and bays, Columbia River and tributaries, and in the Klamath and Trinity Rivers. The tribes manage these fisheries in coordination with the Council.

Council process

The Council’s Salmon Fishery Management Plan guides the management of commercial and recreational salmon fisheries off the coasts of Washington, Oregon, and California. The Council works with treaty tribes and its member states (Washington, Idaho, Oregon and California) on salmon management issues.

Management tools such as season length, quotas, and bag limits vary depending on how many salmon are present. There are two central parts of the fishery management plan: conservation objectives, which are annual goals for the number of spawners of the major salmon stocks (“spawner escapement goals”), and allocation provisions of the harvest among different groups of fishers (commercial, recreational, tribal, various ports, ocean, and inland). The Council must also comply with laws such as the Endangered Species Act.

Every year the Council follows a preseason process to develop recommendations for management of the ocean fisheries (below).

How are salmon counted?

Correctly judging the size of salmon populations is a constant challenge. Salmon are affected by many natural and human-caused factors, so their numbers can vary widely. Estimating the effects of changes in ocean conditions, weather, and freshwater habitat on salmon is difficult. Most models rely on the age structure of a given brood (the various ages of fish that make up the population) in combination with knowledge about environmental conditions over time.

Various methods are used to estimate salmon abundance. For adult salmon, fish trapped in weirs or passing dams are counted as they migrate upstream. Biologists count salmon carcasses and redds (nests) while doing stream surveys. Creel surveys help estimate catch in sport fisheries, and commercially-caught salmon are counted using fish tickets from the sale of fish. As juvenile fish move downstream and migrate to the ocean, smolts are counted in rotary screw traps, snorkel surveys, and electrofishing (using electric current to temporarily stun young fish, which are then captured in a net).

Juvenile salmon may be marked with an internal tag, either a coded wire tag (CWT) or a passive integrated transponder (PIT) tag. CWTs are placed in the snout of the fish and are used mainly in hatchery fish. They are recovered from dead adult salmon. PIT tags are usually placed in the body cavity of the fish and are recovered from dead adults, but they can also be tracked electronically when a fish passes a receiver (for example at a bridge or dam) as it migrates. Both types of tags provide population and distribution data.

Advisory bodies

The Salmon Technical Team (STT) helps the Council by summarizing data from the previous season, estimating the number of salmon in the coming season, and analyzing the effects of the Council’s recommendations and amendments. The STT is made up of eight people drawn from state, Federal, and tribal fisheries management agencies, all of whom have technical expertise in salmon management. STT meetings, like all Council advisory body meetings, are open to the public.

The Salmon Advisory Subpanel is made up of 16 members who represent commercial, recreational, and tribal interests, as well as a conservation representative. These advisors play a large role in developing the Council’s annual salmon management options in March and April.

The Model Evaluation Workgroup (MEW) reviews and modifies models used to predict the effects of harvest on conservation objectives and allocation provisions. The MEW is made up of scientists from state, tribal, and Federal management agencies.

The Habitat Committee tracks habitat issues for the Council. Many (though not all) of these issues involve salmon habitat. For example, the Habitat Committee has developed several Council comment letters on Klamath and Columbia River dam and habitat issues.

How to get involved

There are a few ways to get involved in the Federal salmon management process. First, read up on how salmon are managed and become aware of current salmon fishery issues. Listen in on the salmon agenda items during the March and April Council meetings (see our website, www.pcouncil.org, for details). Provide public comment by using our e-Portal (see the Council website for link and comment deadlines). Attend a salmon season hearing in a coastal community (usually held in March), or sit in on a Salmon Advisory Subpanel, Salmon Technical Team, or Habitat Committee meeting. If you have time, volunteer to serve on an advisory body.

Challenges in salmon management

Besides counting the fish, challenges include coordinating with international, regional, and local agencies and groups; judging the effects of regional fisheries on salmon stocks; recovering salmon under the Endangered Species Act; dividing the harvest fairly; and restoring freshwater habitat.

Current hot topics relating to salmon include offshore aquaculture, offshore wind energy, salmon bycatch in other fisheries, the differences between wild and hatchery salmon, and the role salmon play as forage for predators such as killer whales.

Fact Sheet: Electronic monitoring

At-sea monitoring of all fishing trips (100% monitoring) is required as part of the Council’s groundfish trawl catch share program in order to account for discards. Currently, this monitoring is conducted by human observers.

From 2012 to 2018, the National Marine Fisheries Service (NMFS) studied the use of electronic monitoring (EM) to examine its potential use in monitoring individual fishing quotas under the catch share program, particularly to document at-sea discard events. EM is the use of video technology to track catches and discards, it should not be confused with vessel monitoring systems, which track the location of fishing vessels.

The Council recommended that EM be an option to provide the industry with a potentially less expensive and more flexible alternative to human observers. Under the program, vessel owners could apply for an exemption to the observer requirement, and if approved by NMFS, could use EM to document allowable discards.

Current activities

In 2019 NMFS published regulations to implement the electronic monitoring program for the whiting and fixed gear fisheries operating in the trawl catch share program. Full implementation of the program has been delayed until January 1, 2022. In early 2021, NMFS expects to publish a proposed rule to implement the bottom trawl and nonwhiting midwater trawl fisheries portion of the electronic monitoring regulations.  The Council will continue to work with NMFS and the industry to examine ways to increase efficiencies and lower industry costs while maintaining the integrity and accountability of the catch share program.

Background

The trawl catch share program, which began in 2011, requires 100% monitoring of all trips. Before the program was put in place, 20% of trips were monitored with observers through the NMFS West Coast Groundfish Observer Program; the observers were paid by the Federal government. The Council considered electronic monitoring while planning the catch share program, but opted to continue using observers and increase the observation level to 100%. Under the program, vessel owners must pay private companies to observe all trips. When the catch share program was put in place, NMFS agreed to pay for a portion of the observer costs to help the fleet through the adjustment period. In September 2015, the industry was required to pay the full cost. 

The requirement to pay for observers is one of the most expensive compliance costs associated with participation in the catch share program. All vessels are billed for observers on a per-day basis, so observer costs are the same for both small and large vessels. Because vessels are billed per day both for at-sea and for standby time during a trip, vessels may incur higher costs for standing down due to bad weather; therefore, the observer fee system can put pressure on vessels to fish in unsafe conditions.

Although information collected by observers for catch share monitoring (mainly accounting for discarded fish) could be collected through electronic monitoring, cameras cannot completely fulfill all scientific monitoring needs. Therefore, observers will still be necessary to collect biological samples to support stock assessments and other important fishery-dependent information, such as interactions with protected species.
