Description

Creel surveys were conducted on two of the major fisheries within the Tanana River drainage, Alaska, during 1993. These fisheries included the Salcha River chinook salmon Oncorhynchus tshawytscha fishery and the Chatanika River whitefish spear fishery. Angler effort, harvest and the distribution of harvest of whitefish by angler trip, and angler demographic composition were estimated for the Chatanika River whitefish spear fishery. Angler demographic composition along with effort, catch, and harvest were estimated for the Salcha River chinook salmon fishery. At the Chatanika River, anglers expended a total of 578 hours (SE = 124) to harvest an estimated 609 least cisco Coregonus sardinella, (SE = 62) and 87 humpback whitefish Coregonus pidschian, (SE = 18). Fifty- three percent (SE = 10.0%) of all anglers harvested one or more whitefish. Only 2.5% (SE = 1.0%) of all anglers harvested the daily bag limit of 15 whitefish. The creel survey at the Salcha River chinook salmon fishery was conducted from July 11 through the July 18 which covered only a portion of the entire fishery. During this period anglers expended an estimated 2,595 (SE = 199), angler-hours of effort to catch a total of 77 chinook salmon (SE = 17), of which 54 (SE = 8), were harvested.
