A fishery is the finest scale of resolution captured in Fish Source profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated. Alaska is displaying responsiveness to emerging stock status issues through the regulatory listing of some stocks, declaration of a State of Disaster in some management regions in 2012, and development of a statewide research plan to address knowledge gaps with the species. The 2009 edition of the Pacific Salmon Treaty () stipulated an overall reduction in exploitation rate of the Southeast troll fishery by 30% for 2009-2018 to protect weak stocks. Monitoring of harvest and stock composition in the troll fishery is fairly robust..1.

Monitor the progress in closing out conditions placed upon the certification of the fishery and if agreed timelines are met. Express your support to help meet conditions that may be at a government/regulatory level (where applicable).ticket reporting system and compliance is complete and monitored.

The currently measures the exploitation rate on 48 tagged stocks and abundance of 31 indicator stocks in the Chinook Model.

Genetic studies have also been conducted to confirm the stock composition of Alaska troll catches.

Many stocks in the Arctic-Yukon-Kuskokwim and Cook Inlet regions are exhibiting depressed returns. Mean length at age measures are exhibiting declines among Arctic-Yukon-Kuskokwim stocks. Overages in one year are not corrected for in the next year. The release of adipose fin-clipped hatchery fish without Coded Wire Tags by Pacific Northwest hatcheries is a potential threat to the integrity of the Coded Wire Tagging stock composition monitoring program, long used to estimate hatchery and wild contributions to catch. There is high incidental mortality in the Southeast Alaska troll fishery, amounting to approximately 14% of the legal harvest.1.

Overestimation of the pre-season abundance forecast is an important issue for the Southeast Alaska and Canadian troll fisheries, and has resulted in high cumulative error (harvest vs.

The CTC began the documentation of escapement trends in 1987 (CTC 1988) as part of the effort to assess the rebuilding status of stocks.

In 2009, PSC established a 5-year Sentinel Stock Program to develop better estimates of escapement for certain key stocks or stock groups (CTC 2011c).

post-season allowable catch) over the last 13 years. The release of adipose fin-clipped hatchery fish without Coded Wire Tags (CWTs) by Pacific Northwest hatcheries is compromising the integrity of the CWT stock composition monitoring program. The Alaskan legislature recently failed to renew the Alaska Coastal Zone Management Program, putting salmon habitat in the region at risk. There is high incidental mortality in the fishery, amounting to approximately 14% of the legal harvest. Escapement is insufficiently monitored in some geographies that produce the fishery’s target stocks (for example, the Upper Georgia Strait in British Columbia).1.

Monitor the progress in closing out conditions placed upon the certification of the fishery and if agreed timelines are met. Express your support to help meet conditions that may be at a government/regulatory level (where applicable).
