Abstract: | Estimates of Pacific salmon Oncorhynchus spp. escapement for the Nushagak River in Bristol Bay, Alaska, were determined by hydroacoustic techniques from June 12 through August 21, 2001. Estimates of species, age, sex, and size composition were derived from samples obtained with drift gillnets and beach seines. Final escapement estimates by species through August 21 were 803,537 sockeye salmon O. nerka, 92,275 chinook salmon O. tshawytcha, 547,995 chum salmon O. keta, and 68,364 coho salmon O. kisutch. |
