Short Communication: Effects of Hypoxic Stress on Electrolyte Levels of Blood in Juvenile Rainbow Trout (Oncorhynchus mykiss)

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...

Effects 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 (...

The effects of density on territory size and population regulation in juvenile rainbow trout, Oncorhynchus mykiss

The effects of density on territory size and population regulation in juvenile rainbow trout, Oncorhynchus mykiss Jacquelyn Lee Ann Wood Despite a wealth of research on territoriality and population regulation in stream dwelling salmonids, most studies have focused on manipulations of food abundance alone, or else have simultaneously manipulated space and food abundance, but used population den...

Effects of chitosan on hematological parameters and stress resistance in rainbow trout (Oncorhynchus mykiss)

The aim of our study was to evaluate the effects of chitosan as immune stimulator on some hematological parameters and stress resistance in rainbow trout. Nine hundred rainbow trout (with initial body weight of 25 ± 0.1 g) were obtained from a local farm and acclimated to the laboratory conditions for one week. After that fish were randomly divided into four groups in three replicates. Each gro...

Effects of dietary rainbow trout (Oncorhynchus mykiss) viscera protein hydrolysate on some hematological and blood serum biochemical parameters of rainbow trout juvenile

The aim of this study was to prepare rainbow trout (Oncorhynchus mykiss) visceral protein hydrolysate (VPH), determine the peptide molecular weight and using rainbow trout visceral protein hydrolysate in diet of rainbow trout juvenile to investigate its effects on some hematological and blood serum biochemical parameters. The viscera of rainbow trout were hydrolyzed by alcalase enzyme and Antio...
