The rainbow trout population in Elder Creek, Oregon was
studied between June 1965 and November 1966. The physical characteristics
of the stream during the summer season were described.
Rainbow trout were captured in each of three sections on the stream
by electrofishing and were tagged and measured. Population size,
mortality,...
"In January 1946 the Oregon State Game Commission authorized a study of Diamond Lake to determine reason for an apparent decline in the size and number of rainbow trout with the object of maintaining a maximum annual yield through proper management." (From Introduction)
This report consists of tables summarizing data regarding streams receiving hatchery-reared rainbow trout since 1952. It includes data such as sources, sizes of fish, and water temperatures at the planting sites. It also averages data from creel reports from 1965-1972.
The DNA repair capabilities of rainbow trout (Salmo gairdneri)
were studied vising the method of autoradiography. Trout were fed a
semi-purified control diet containing 0 ppm, 50 ppm, or 300 ppm
cyclopropenoid fatty acids (CPFA) for 6-9 weeks. Liver slices were
prepared and exposed in vitro to a control treatment,...
This study was conducted to investigate the accumulation of dietary polychlorinated biphenyls (PCB's) by a Mt. Shasta strain of rainbow trout (Salmo gairdneri). A commercial mixture of PCB's (Aroclor 1254) was added to the diet at a level of 15 ppm on a dry weight basis. Accumulation of PCB's was...
The toxicity of chlorobenzene (CB) was investigated in rainbow
trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil)
and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously
flowing system for 15 and 30 days.
In the acute study, overt toxicity...
The acute phase response (APR) includes an early response of the innate immune
system to an inflammatory agent. Acute phase proteins (APP) are produced at
increased rates in the liver during this response. The APR has been well
characterized in mammals, but it is unclear to what degree teleosts mount...
Aflatoxin B₁ (AFB₁) is a mold-produced toxin which has been shown
to be a potent hepatocarcinogen in many animal species. Of the
species studied thus far, rainbow trout have proven to be the most
sensitive. Experiments were conducted to investigate various aspects
of AFB₁ metabolism in this species, including in...
