4 Harvest, escapement, and total run size estimates used for high and low estimates of harvest rates of even year wild pink salmon in Prince William Sound, Alaska, – 25 5 Harvest, escapement, and total run size estimates used for high and low estimates of harvest rates of. Coho Salmon Life History. The coho salmon life history is relatively straight-forward. Smolts typically migrate to sea in the spring of their second year, spend months rearing in the ocean, then return to freshwater as three-year-old adults. A returning adult may measure more than two feet in length and weigh an average of eight pounds.
Note: ADF&G emergency closed the river sport fishery to bait fishing effective August 6, in an effort to attain adequate coho salmon escapement numbers. Most sport anglers are willing to take a cutback in fishing methods and means inorder to maintain salmon numbers, however, the Department has done nothing to reduce the harvest of coho salmon. P. O. Box , King Salmon, Alaska , () Abstract. - From 26 July to 28 September , hourly counts were conducted from counting towers to estimate the escapement of coho salmon Oncorhynchus kisutch into the Ugashik lakes. Estimated escapement for the season was 3, coho salmon and daily escapement.
near term risk of insufficient escapement of coho salmon in the Bartlett River. Stock ( ) in sport fishing effort. Sport harvest of coho salmon in the Bartlett River from to appears to be somewhat variable with no significant trend. Survey Counts. As of August 3, , only coho salmon had passed upstream of the weir and the escapement is projected to be 4, fish at the 15th percentile of the historical this time, it is justified to slow the harvest of coho salmon at the Little Susitna River until the run can be further assessed to ensure the SEG is met.”.

Sport fishing effort has increased dramatically in recent years, but the sustainability of the current harvest is unknown. This project will provide quantitative estimates of escapement (the number of fish that escape harvest and reach spawning grounds), which are paramount for evaluating future fishery sustainability.

K) under Project. Sport fishery management for salmon in the AYK region has little effect on annual spawning escapements of salmon due to low levels of harvest. Sport fishing gear is inherently inefficient and catch rates are variable.
Bag limits are low in number and the focus of many anglers is on catch-ing and releasing salmon, not on harvest. Historically, by this date, approximately 52 percent (2,) of Coho Salmon have passed the weir.
In an effort to conserve Buskin Lake Coho Salmon, the ADF&G has prohibited commercial and subsistence salmon harvest in the marine waters adjacent to the Buskin and also has closed sport harvest of Coho Salmon in the Buskin drainages.The Little Susitna River coho salmon sustainable escapement goal (SEG) is 10,– Harvest can exceed.
