Coho salmon stock status and escapement goals in Southeast Alaska

http://www.adfg.alaska.gov/FedAidpdfs/SP11-23 The status of coho salmon stocks in Southeast Alaska was assessed from information on escapement, smolt abundance, marine survival, and total abundance from coded-wire-tagged indicator stocks and from stocks returning to streams that were surveyed for escapement. Escapements to monitored streams remained within or above biological escapement goal ranges during 2008–2010. We identified no … Continue reading »
