Book Description
This report contains recommendations after the Alaska Department of Fish and Game Escapement Goal Review Committee reviewed Pacific salmon, Oncorhynchus spp., escapement goals for the major river systems in Bristol Bay. Spawner-return data were evaluated for: sockeye salmon, O. nerka, in the Ugashik, Egegik, Kvichak, Naknek, Alagnak, Wood, Nushagak, Igushik, Togiak, and Kulukak Rivers; chinook salmon, O. tshawytscha, in the Nushagak, Togiak, Alagnak, Naknek, and Egegik Rivers; chum salmon, O. keta, in the Nushagak River; coho salmon, O. kisutch, in the Togiak, Nushagak, and Kulukak Rivers; and pink salmon, O. gorbuscha, in the Nushagak River.

Book Description
The Alaska Department of Fish and Game interdivisional escapement goal review committee reviewed Pacific salmon Oncorhynchus spp. escapement goals for the major river systems in Bristol Bay. There were 15 escapement goals examined in the Bristol Bay management area for this review. The committee evaluated spawner-return data for most Bristol Bay sockeye salmon O. nerka and Chinook salmon O. tshawytscha stocks with escapement goals.

Book Description
This report summarizes statewide Pacific salmon escapement goals in effect in 2016 and documents escapements for all species and stocks with goals from 2008 through 2016. Annual escapements are compared against escapement goals in place at the time to assess outcomes, with summaries by the Division of Commercial Fisheries regions. We list methods used to enumerate escapements and to develop current escapement goals (with brief descriptions) for each monitored stock. Escapement goals were reviewed for Bristol Bay, Arctic-Yukon-Kuskokwim, Alaska Peninsula/Aleutian Islands, and Chignik management areas leading up to the 2015/2016 Board of Fisheries meeting cycle. As a result of these reviews, there were 25 escapement goal changes in 2016, including the elimination of 12 goals and the establishment of 3 new goals. In 2016, 72% of the escapement goals were met or exceeded; whereas 28% of the stocks did not meet minimum escapement goals.
