Effects of melatonin on the levels of antioxidant enzymes including catalase (CAT), peroxidase (POD), glutathione reductase (GRd), and malondialdehyde (MDA), a lipid peroxidation marker, in erythrocytes of rainbow trout (Oncorhynchus mykiss) were investigated. The results showed that melatonin statistically activated the CAT, POD, and GRd activity (P < 0.05). Moreover, MDA levels were significa...

We present here the draft genome of a pathogenic Yersinia ruckeri strain, isolated from rainbow trout (Oncorhynchus mykiss) affected by enteric redmouth disease. The chromosome has 3,826,775 bp, a GC content of 46.88%, and is predicted to contain 3,538 coding sequences. The data will be useful for comparative pathogenicity studies.

An Evaluation of Stress Induced Hortality of Stocked Catchable-sized Rainbow Trout in Temple Fork of the Logan River

The efficiency with which fish and other animals add and maintain body proteins is a balance between synthesis of proteins and their degradation. In fish that have similar food consumption and protein synthesis rates, a greater ratio of synthesis to degradation would be expected to produce more efficient conversion of food into growth. In addition, we hypothesised that high activities of the pr...

The study of inter-individual variability of personality in fish is a growing field of interest but the genetic basis of this complex trait is still poorly investigated due to the difficulty in controlling fish genetic origin and life history. When available, isogenic lines that allow performing independent tests on different individuals having identical genotype constitute a very relevant expe...

We report here the complete genome sequence of Weissella ceti strain WS08, an emerging pathogen to farm-raised rainbow trout. The genome of strain WS08 is composed of a circular chromosome with 1,355,853 bp and a G+C content of 40.78%.

The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream behavior in the migratory form, and testosterone inhibits onset of this behavior. To elucidate differences in sensitivity to water temperature decreases between the migratory and non-...
