Temperature influences the incidence of chemically induced cancer in fish,
with warmer temperatures being associated with higher cancer incidence. The
mechanisms of temperature-modulated chemical carcinogenesis in fish, however,
have not been described in detail. Therefore, one primary objective of this study
was increased understanding of how temperature-modulated genotoxicity of 7,12-...
A dietary level of Aroclor 1254 (100 ppm) was fed to rainbow trout (Salmo gairdneri) for 15 weeks to determine the effects on hepatic microsomal enzyme induction. Fish were also fed combined polychlorinated biphenyl (PCB) (100 ppm) and cyclopropene fatty acids (CPFA) (50 ppm) to determine the effects on mixed...
A suitable method for the utilization of shrimp processing waste was investigated. The shrimp waste, which consisted of shell, viscera, and residual meat particles, was dried into a pink meal. This meal contained 5.4 percent moisture, 23.5 percent ash, 4. 1 percent crude lipid, 36. 3 percent actual protein, and...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
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 objective of the reservoir research project is to gather and assemble data concerning the game and rough fish populations in Round Butte, Prineville, and Ochoco Reservoirs to enable efficient management of the fisheries.
The project has been divided into three different jobs, and these are:
a. Job 1 -...
