Formalin in the Hatchery

FORMALIN is used extensively in hatcheries to control external parasites of fish. There are reports that formalin is toxic at some hatcheries, especially when used on rainbow trout (Salmo gairdneri). This is a discussion of the development of the use of formalin to control fish parasite-in the hatchery, its properties, and some experimental work.

Co-oxidation of the sulfur-containing amino acids in an autoxidizing lipid system

Oxidation of the sulfur amino acids by autoxidizing lipids was studied in a model system consisting of an amino acid dispersed in cold-pressed, molecularly distilled menhaden oil (20–80% w/w). Under all conditions investigated, cysteine was oxidized completely to cystine. Preliminary results suggest that at 110°C the oxidation follows first-order kinetics for at least the first 8 hr. A specific re

Mycobacteria in adult salmonid fishes returning to national fish hatcheries in Washington, Oregon and California in 1958-59

Incidence of acid-fast bacillus infections in salmonid fishes at West Coast hatcheries was determined for 1957-59. No evidence was obtained which would indicate a definite trend towards either increased or decreased rates of infection. It is apparent that the incidence of infection is higher in hatchery-marked fish than in unmarked fish. Only one hatchery was found free of infection during the 3 y

A method for live-trapping dusky grouse

A drive trap, used to capture dusky grouse (Dendragapus obscurus obscurus) females and their broods for transplantation, is described. The trap consists of two 75-foot wings, leading to a netting-covered enclosure with a smaller wooden catch box at the rear. A four-man crew finds a brood in open cover and, while one or two men keep the brood under observation, the others rig the trap along the bir
