Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...
Whole body accumulation and tissue distribution of dieldrin
(HEOD1) in rainbow trout was studied through oral dose disposition
tests and subchronic exposures via water (0.04 and 0.08 jig dieldrin/l)
and/or diet (0.087 jig dieldrin/g fish/day). Growth and maintenance
rations of 4 and 2% body weight/day were employed. Subchronic testing
produced...
Rats exposed to one or two doses of 60 mg mirex/kg
by gavage exhibited hypertrophied livers and various
degrees of hepatobiliary dysfunction. Although single
dosed animals demonstrated elevated whole liver bile flow
after 96 hours, the single dose was insufficient to
significantly inhibit whole liver hepatobiliary
performance as measured by...
Effects of diet on food energy utilization by grass
carp fed aquatic plants or formulated diets with varied
lipid sources and levels are presented in three
manuscripts. Significant effects of diet on food
consumption, digestion, growth and muscle fatty acid (FA)
composition of fingerling diploid grass carp fed aquatic
macrophytes...
Rainbow trout were exposed to aluminum at pH 7.25 and
8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃)
for 96 hours in a continuous-flow system and mortality and
aluminum accumulation in the gills were determined.
Temperature, pH, and dissolved oxygen were measured
daily for each treatment. Dissolved...
