Length Frequency and Age Distribution of Resident Fish Collected from Rivers Within Togiak National Wildlife Refuge, Alaska, 1996. Fishery Data Series Number 97-4

摘要

Baseline age, weight and length (AWL) sampling of resident fish species was conducted by U.S. Fish and Wildlife Service field crews on seven creeks and rivers within the Togiak National Wildlife Refuge in 1996. A total of 670 rainbow trout, 349 Arctic grayling, 187 char, and 34 northern pike were sampled. All fish species were collected with hook and line methods. Rainbow trout in all creeks and rivers were marked with individually numbered Floy(TradeName) spaghetti tags. In addition, char sampled in the Osviak and Matogak Rivers were tagged. Two nominations to the Alaska Department of Fish and Game's Atlas of Waters Important to the Spawning, Rearing or Migration of Anadromous Fishes were submitted. Trip report summaries from the 1996 field season are included as appendices. The purpose of this report is to compile fisheries biological data and make it available to fisheries biologists and managers. All raw data summarized in this report are available in electronic format archived with the Alaska Department of Fish and Game and this office.
