Description

As part of a continuing stock assessment program in Southeast Alaska, the Division of Sport Fish obtained indices of escapement for chinook salmon Oncorhynchus tshawytscha in designated streams and transboundary rivers. The estimated total escapement in 1997 was 108,039 large (age .3 and older) chinook, an 18% decrease from the 131,356 fish estimated in 1996. The 1997 estimate was over twice the 19751980 base period average of 42,437 chinook salmon, 172% of the 19811985 average of 62,591 and 121% of the 19861990 average of 89,249. The estimated total exceeded the goal for the region for the third time in 4 years, primarily due to continued high escapement to the Taku River. Escapement indices exceeded management goals in the Taku, Stikine, Situk, Chilkat and King Salmon Rivers and were near goal in the Keta River. The Alsek River escapement declined but still exceeded the newly revised goal. Escapements to the Unuk, Chickamin and Blossom Rivers declined from 1996 and remained below goals.
