Rainbow Trout, Oncorhynchus mykiss
Rainbow trout are classified as Oncorhynchus mykiss, and as such belong to the same genus as Pacific salmon, and to the family Salmonidae, which includes Atlantic salmon (Salmo salar), various trout (Salvelinus sp.), Arctic char (Salvelinus alpinus), Arctic grayling (Thymallus arcticus) and whitefish (Coregonus sp.). Rainbow trout are native to areas around the North Pacific Ocean, from souther...
متن کاملEffects of sublethal ammonia exposure on swimming performance in rainbow trout (Oncorhynchus mykiss).
Adult trout Oncorhynchus mykiss fitted with a dorsal aortic catheter were exposed to 288+/-15 micromol l(-1) (mean +/- S.E.M.) total ammonia for 24h in water at a pH of 8.39+/-0.02, while swimming at a speed equivalent to 0.75 bodylengths s(-1) (BLs(-1)) in a Brett-type tunnel respirometer. The fish were then exposed to stepwise increments in swimming speed (0.25 BLs(-1) every 30 min) until exh...
متن کاملBiochemical characterization of microcystin toxicity in rainbow trout (Oncorhynchus mykiss).
The kinetics and biochemical effects of microcystins in rainbow trout were studied with freeze-dried toxic cells of Microcystis aeruginosa, strain PCC 7806. Following in vivo exposure the changes in liver histology were observed over a 72 hr period and the absorption of microcystins from the gastrointestinal tract into the blood and liver, as well as the inhibition of hepatic protein phosphatas...
متن کاملEffects of dietary selenomethionine on larval rainbow trout (Oncorhynchus mykiss).
Increased selenium (Se) concentrations in water (>10 microg/L) have been measured in the San Diego Creek, which is a tributary of the Upper Newport Bay in Orange County, CA. The objective of this study was to develop tissue- and dietary-based thresholds for Se in resident fish species in San Diego Creek. A 90-day dietary experiment was conducted to determine the effects of seleno-L-methionine (...
متن کاملCopper metabolism and gut morphology in rainbow trout (Oncorhynchus mykiss) during chronic sublethal dietary copper exposure
Juvenile rainbow trottt (Oncorhynchus mykiss) werc exposed to I I (control), 300 (medium), and 1000 pg Cug-r (high) (as CuSOa.5H2O) in the diet for 28 days at a daily ration of 4%o wet body weight, with a background waterborne Cu concentration of3 pg.L-|. There was no effect ofdietary Cu on growth, condition factor, or food conversion efficiency. Whole-body Cu content increased continuously ove...
