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,...
The fall chinook index of abundance was 128% of the long-term average, and presumably would have been even higher had survey conditions in the central and north coast not been so difficult.
The surveys of spawning fish in coastal rivers in 1971 indicate that stocks of chum salmon remain at a low, although apparently stabilized level. Fluctuations are probably the result of year-class survival and age at maturity, rather than continued decline of the species.
The fall chinook index of abundance was...
