Effects of deltamethrin on rainbow trout (Oncorhynchus mykiss)
Environmental Toxicology and Pharmacology, 2007The aim of this study was to assess the effect of deltamethrin on rainbow trout (Oncorhynchus mykiss). Control and experimental group of fish were exposed to Decis EW 50 pesticide preparation (active substance 50g/l of deltamethrin). The acute semistatical toxicity test lasting 96h was performed on rainbow trout juveniles.

Anorexia Reduces the Severity of Cryptobiosis in Oncorhynchus mykiss
The Journal of Parasitology, 1991Cryptobia salmositica multiplied more rapidly and caused a more severe disease with a higher mortality (65%) in rainbow trout (Oncorhynchus mykiss) fed a 52% protein diet than in fish fed 37 or 22% protein diets (25 and 30% mortalities, respectively). Also, plasma protein was significantly higher in fish fed a 52% protein diet than in fish fed 37 or 22%

On Catching Humpback Salmon Oncorhynchus gorbuscha and Chum Salmon Oncorhynchus keta of Rare Age
Russian Journal of Marine Biology, 2002Data on catching humpback salmon Oncorhynchus gorbuscha at the age of 0 + and chum salmon Oncorhynchus keta at the age of 1+ in the Ilyushina River (Kunashir Island) in the period of spawning migration are given. The sex of fish, the body length, the stage of gonad maturity, and the number and width of sclerites on scales are indicated.

Characterization of coho salmon (Oncorhynchus kisutch) insulin
Regulatory Peptides, 1985Insulin has been isolated from islet tissue of coho salmon (Oncorhynchus kisutch) by gel filtration and HPLC and the complete amino acid sequence has been determined. The sequence differs from bovine insulin at 14 sites but all interchanges are conservative from the viewpoint of preservation of conformation. A comparison of insulin sequences from other

Antibacterial proteins in rainbow trout, Oncorhynchus mykiss
Fish & Shellfish Immunology, 2000Antibacterial proteins are an important part of the innate immune system for all animals. They have been extensively studied in mammals, amphibians and invertebrates, but have received only scant attention in fish. Their expression and processing, however, provide a way of monitoring defence vigour during development or with seasonal changes in ...

Journal of Parasitology, 2004
The myxosporean parasite Parvicapsula minibicornis is described from adult sockeye and coho salmon during spawning migrations in tributaries of the Columbia River in Canada and the United States. These observations extend the known distribution of this parasite from the Fraser River drainage basin.

Genetic history of salmonid fishes of the genus Oncorhynchus
Russian Journal of Genetics, 2015This review discusses genetic approaches to solving important problems of evolutionary biology of salmonid fishes with special reference to Pacific salmon and trout. The problems of the genetic phylogeny of salmonid fishes, including issues of the consistency/inconsistency of phylogenetic tree topologies built using genetic and phenotypic ...

The Origin and Speciation of Oncorhynchus Revisited
1997Thirty-seven years have passed since Ferris Neave published his classic paper on the origin and speciation of the salmonid genus, Oncorhynchus. Since then, new data on fossils, chromosomes, molecules, and morphology have accumulated, and new analytical techniques for quantifying phylogenetic data have been developed.

Cytogenetic and genome research, 2007
Fluorescence in situ hybridization (FISH) using a probe to the male-specific GH-Y (growth hormone pseudogene) was used to identify the Y chromosome in the karyotypes of chum salmon (Oncorhynchus keta) and pink salmon (Oncorhynchus gorbuscha). The sex chromosome pair is a small acrocentric chromosome pair in chum salmon and the smallest metacentric ...
