  1 Effort in different zones are based on logbook records, where locations are self-reported by vessels.                                  
  2 Estimates of Canadian effort in boat fishing days are expanded using the methodology described in Stocker et al. (2007:  CTRFAS  2701).  1995-2011 data from Canadian Tuna Database version 13.02.11                          
  3 Number of vessels that fished in US EEZ: 1995-2008 data from Canadian Tuna Database version 13.02.11, 2009-2011 data from DFO Pacific Licensing System                              
  4 Vessel Months during 1995-2011 used data from Canadian tuna database v. 13.02.11                                    
  5 Number of vessels that fished in Canadian EEZ: 1995-2011 data from Tuna Database version 13.02.11                                  
  6 Although the historical level of fishing effort for the US fleet was permitted in the Canadian EEZ during 2009-2011, the historical level of fishing effort is not presently quantified.                            
  7 Number of US vessels that fished in US or Canadian EEZs are not expanded.                                      
  8 Number of US vessels that fished in US or Canadian EEZs refers to vessels that recorded fishing days in those zones in their logbooks and do not include vessels that only had transit days. Where logbook coverage rate is less than 100%, it is assumed that all US vessels that landed fish, had fished in the US EEZ          
  9 Preliminary data subject to change. Canadian data from Canadian tuna database version 19.03.31                                  
10 Estimates of US effort in US EEZ, Canadian EEZ and high seas in boat fishing days are expanded and calculated by multiplying the proportion of reported logbook effort in each zone by the estimated annual effort. Estimation of annual effort has changed in 2017 (Documented in ISC working paper ISC17/STATWG/WP-1)
11 Proportion of US effort in high seas zone was estimated from logbook data, and includes effort in U.S. EEZ off Alaska.
