Available in PDF, EPUB and Kindle. Book excerpt: Marine boat sport anglers throughout Southeast Alaska target and harvest Chinook salmon Oncorhynchus tshawytscha, coho salmon O. kisutch, Pacific halibut Hippoglossus stenolepis, lingcod Ophiodon elongatus, a variety of rockfish species Sebastes spp., and sablefish Anoploploma fimbria primarily during April to September. Angler effort, catch, and harvest data will be collected from late April to early September from returning marine boat anglers at the following ports: Yakutat, Elfin Cove, Gustavus, Juneau, Sitka, Petersburg, Wrangell, Ketchikan, Craig, and Klawock. Harvest sampling will be used to collect biological samples and associated data to estimate the age, length, and genetic composition of the Chinook salmon harvest, and Chinook and coho salmon will be inspected for missing adipose fins, indicating the head should be removed to recover a coded wire tag. Contributions of hatchery and wild coded-wire-tagged stocks (both Chinook and coho salmon) to the sport harvest will be estimated for all sampled ports, and the wild mature component of the Chinook salmon harvest in Division of Commercial Fisheries Salmon District 108 (Petersburg-Wrangell) and District 111 (Juneau) will also be estimated. Biological data from harvested Pacific halibut (lengths), lingcod (lengths and sex), and rockfish (lengths) will be collected from guided and unguided marine boat anglers. The length data will be converted via established species-specific, length-weight relationships to estimate average weights by species and angler type.
