ABCAcceptable biological catch. See below.
acceptable biological catchThe ABC is a scientific calculation of the sustainable harvest level of a fishery and is used to set the upper limit of the annual total allowable catch. It is calculated by applying the estimated (or proxy) harvest rate that produces maximum sustainable yield to the estimated exploitable stock biomass (the portion of the fish population that can be harvested).

coastal pelagic speciesCoastal pelagic species are schooling fish, not associated with the ocean bottom, that migrate in coastal waters. They usually eat plankton and are the main food source for higher level predators such as tuna, salmon, most groundfish, and humans. Examples are herring, squid, anchovy, sardine, and mackerel.
Coastal Zone Management ActThe main objective of the CZMA is to encourage and assist states in developing coastal zone management programs, to coordinate state activities, and to safeguard the regional and national interests in the coastal zone. It requires that any federal activity (including fishery management regulations) directly affecting the coastal zone of a state be consistent with that state’s approved coastal zone management program, since activities that take place beyond the territorial sea may affect the coastal zone.
Code of Federal RegulationsA codification of the regulations published in the Federal Register by the executive departments and agencies of the federal government. The CFR is divided into 50 titles that represent broad areas subject to federal regulation. Title 50 contains wildlife and fisheries regulations.

FThe instantaneous rate of fishing mortality. The term “fishing mortality rate” is a technical fishery science term that is often misunderstood. It refers to the rate at which animals are removed from the stock by fishing. The fishing mortality rate can be confusing because it is an “instantaneous” rate that is useful in mathematical calculations, but is not easily translated into the more easily understood concept of “percent annual removal.”

Membership varies in size depending on the number of states involved. There are eight regional Councils, including the Pacific Council.
Fishery management planA plan, and its amendments, that contains measures for conserving and managing specific fisheries and fish stocks.
Fishery management unitThe species or stocks of fish managed under a fishery management plan.
FishingThe catching, taking, or harvesting of fish; the attempted catching, taking, or harvesting of fish; any other activity that can reasonably be expected to result in the catching, taking, or harvesting of fish; any operations at sea in support of, or in preparation for, any of these activities. This term does not include any activity by a vessel conducting authorized scientific research.
Fishing communityA community which is substantially dependent on or substantially engaged in the harvest or processing of fishery resources to meet social and economic needs. Includes fishing vessel owners, fishing families, operators, crew, recreational fishers, fish processors, gear suppliers, and others in the community who depend on fishing.
Fixed gearFishing gear that is stationary after it is deployed (unlike trawl or troll gear which is moving when it is actively fishing). Within the context of the groundfish limited entry fleet, “fixed gear” means longline and fishpot (trap) gear. Within the context of the entire groundfish fishery, fixed gear includes longline, fishpot, and any other gear that is anchored at least at one end.

Minimum stock size thresholdA threshold biomass used to determine if a stock is overfished. The Council proxy for MSST is B25%.
Mixed stock exceptionIn “mixed-stock complexes,” many species of fish swim together and are caught together. This becomes a problem when some of these stocks are healthy and some are overfished, because even a sustainable harvest of the healthy stocks can harm the depleted stock. In order to avoid having to shut down all fisheries to protect one particular overfished stock, the national standard guidelines allow a “mixed-stock” exception to the “overfished” definition. This would allow higher catches of some overfished species than ordinarily allowed in order to avoid severe hardship to fishing communities.

National Environmental Policy Act.Passed by Congress in 1969, NEPA requires Federal agencies to consider the environment when making decisions regarding their programs. Section 102(2)(C) requires Federal agencies to prepare an Environmental Impact Statement (EIS) before taking major Federal actions that may significantly affect the quality of the human environment. The EIS includes: the environmental impact of the proposed action, any adverse environmental effects which cannot be avoided should the proposed action be implemented, alternatives to the proposed action, the relationship between local short-term uses of the environment and long-term productivity, and any irreversible commitments of resources which would be involved in the proposed action should it be implemented.

Open-access fisheryThe segment of the groundfish fishery or any other fishery for which entry is not controlled by a limited entry permitting program.
Optimum yieldThe 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. In the case of overfished fisheries, the OY provides for rebuilding to a level that is consistent with producing the Maximum Sustained Yield for the fishery.
OSPOptimum sustainable production, Oregon State Police
OSUOregon State University
OvercapacityA level of fishing pressure that threatens to reduce a stock or complex below the abundance necessary to support maximum sustainable yield and allow an economically sustainable fishing industry.
OverfishedAny stock or stock complex whose size is sufficiently small that a change in management practices is required to achieve an appropriate level and rate of rebuilding. The term generally describes any stock or stock complex determined to be below its overfished/rebuilding threshold. The default proxy is generally 25% of its estimated unfished biomass; however, other scientifically valid values are also authorized.
OverfishingFishing at a rate or level that jeopardizes the capacity of a stock or stock complex to produce MSY on a continuing basis. More specifically, overfishing is defined as exceeding a maximum allowable fishing mortality rate. For any groundfish stock or stock complex, the maximum allowable mortality rate will be set at a level not to exceed the corresponding MSY rate (FMSY) or its proxy.

Rebuilding analysisAn analysis that uses biological information to describe the probability that a stock will rebuild within a given timeframe under a particular management regime.
Rebuilding planA document that describes policy measures that will be used to rebuild a fish stock that has been declared overfished.
RecFinRecreational Fishery Information Network. A database managed by the Pacific States Marine Fisheries Commission that provides recreational fishery information for Washington, Oregon, and California.
RecruitsRecruits are a group (“cohort”) of young fish that enter a fish stock in one year.
Recruits/recruitmentThe estimated production of new members to a fish population as measured at a specific life stage.
Regulatory Flexibility Analysis (or Act).Regulatory Flexibility Act (see IRFA and FRFA above). See below. The Regulatory Flexibility Act (5 U.S.C. 601-612) requires federal agencies to consider the effects of their regulatory actions on small businesses and other small entities and to minimize any undue disproportionate burden.
Regulatory Impact ReviewRIRs are prepared to determine whether a proposed regulatory action is “major.” The RIR examines alternative management measures and their economic impacts.

Riparian areaA land area adjacent to water. Technical definition: “riparian area” means an area of land that (a) is adjacent to a stream, river, lake or wetland, and (b) contains vegetation that, due to the presence of water, is distinctly different from the vegetation of adjacent upland areas. (Code of British Columbia)

RulemakingThe process of developing Federal regulations which occurs in several steps, including publishing proposed rules in the Federal Register, accepting comments on the proposed rule, and publishing the final rule. An “advanced notice of proposed rulemaking” is published when dealing with especially important or controversial rules.
SAFEStock assessment and fishery evaluation. See below.
Saltonstall-Kennedy ActThe Saltonstall-Kennedy Act allocates 30% of the duties for imported fishery products to technological, biological, marketing, and other research and services in order to promote the free flow of domestically-produced fishery products and to develop markets for domestic fishery products.
SASSalmon Advisory Subpanel
Scientific and Statistical CommitteeAn advisory committee of the PFMC made up of scientists and economists. The Magnuson-Stevens Act requires that each council maintain an SSC to assist in gathering and analyzing statistical, biological, ecological, economic, social, and other scientific information that is relevant to the management of Council fisheries.

Spawning biomassThe biomass of mature female fish at the beginning of the year. If the production of eggs is not proportional to body weight, then this definition is construed to be proportional to expected egg production.
SPRSpawning biomass per recruit
SPRSpawning potential ratio. The ratio of spawning potential per recruit under a given fishing regime, relative to the spawning potential per recruit with no fishing.

STARStock assessment review
STAR PanelStock Assessment Review Panel. A panel set up to review stock assessments for particular fisheries. In the past there have been STAR panels for sablefish, rockfish, squid, and other species.
Stock Assessment and Fishery Evaluation.A SAFE document is a document prepared by the Council that provides a summary of the most recent biological condition of species in the fishery management unit, and the social and economic condition of the recreational and commercial fishing industries, including the fish processing sector. It summarizes, on a periodic basis, the best available information concerning the past, present, and possible future condition of the stocks and fisheries managed in the FMP.

TACTotal allowable catch. See below.
Territorial seaThe territorial sea of the United States extends 12 nautical miles offshore. States exercise authority over marine fisheries in waters from the coastline to 3 miles offshore.
TMAXThe maximum time period to rebuild an overfished stock, according to National Standard Guidelines. Depends on biological, environmental, and legal/policy factors.
TMINThe minimum time period to rebuild an overfished stock, according to National Standard Guidelines. Technically, this is the minimum amount of time in which a fish stock will have a 50% chance of rebuilding if no fishing occurs (depends on biological and environmental factors).
TNCThe Nature Conservancy
Total allowable catchThe total regulated catch from a stock in a given time period, usually a year. (NMFS)
Total catch OYTotal catch optimum yield. The landed catch plus discard mortality.
TTARGETThe target year, set by policy, for a fish stock to be completely rebuilt.
