Sampling Juvenile Chinook Salmon ('Oncorhynchus tshawytscha') and Coho Salmon ('O. kisutch') by Small Trolling Gear in the Northern and Central Regions of Southeastern Alaska, 1985

摘要

Juvenile chinook salmon (Oncorhynchus tshawytscha) and coho salmon (0. kisutch) were sampled by small trolling gear in the marine waters of southeastern Alaska from January to December 1985 to determine their stock composition, age, size, distribution, and abundance. In 95 vessel days (799.5 hours) of fishing effort, 2,138 chinook salmon and 500 coho salmon were sampled by five vessels. Coded-wire tags were recovered from 131 chinook salmon, and most (93) of these fish originated from southeastern Alaska, followed by British Columbia, Washington, and Oregon.
