This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...

It includes the results of interviews with anglers on the lake, and a summary of the data regarding their catches. It also delineates information regarding kokanee growth, distribution, and maturation, and...
The latest phase of a study of the migration, survival, growth, and catch of coastal cutthroat trout, conducted to compare cutthroat trout and rainbow trout. The document describes the geological and biological characteristics of Munsel Creek weir, where the studies were conducted. It also includes graphs of the data and...
This report summarizes research on coastal cutthroat trout from the beginning of more intensive studies in 1962 through 1965. Early work involved studies of the growth, survival and catch of hatchery-reared cutthroat in coastal lakes, with a change in 1965 to research in coastal streams and estuaries. Research is continuing,...
A fish hatchery was built on the Salmon River and began operating in late 1976. The early part of this study describes pre-hatchery status of salmonids in the river. Later work formulated a hatchery-rearing program.
Sampling with seine and trawl from May 1974 to November 1976 indicated that the species composition and distribution of fishes in Tillamook Bay through time is primarily related to the movements of marine species in and out of the estuary. Northern anchovy (Engraulis mordax), surf smelt (Hypomesus pretiosus), and shiner...
