Anorexia Reduces the Severity of Cryptobiosis in Oncorhynchus mykiss

The Journal of Parasitology, 1991
Cryptobia 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%

Antibacterial proteins in rainbow trout, Oncorhynchus mykiss

Fish & Shellfish Immunology, 2000
Antibacterial 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 ...

The effect of foodborne sertraline on rainbow trout (Oncorhynchus mykiss)

Science of The Total Environment, 2020
The worldwide consumption of antidepressants is raising as well as their concentrations in the aquatic environment. This increases the risk of food chain contamination and bioaccumulation in aquatic biota. The aim of this study was to describe a potential risk of sertraline as a pollutant from water environment, wherein rainbow trout (Oncorhynchus ...

Early gill development in the rainbow trout,Oncorhynchus mykiss

Journal of Morphology, 1996
The morphology of the gills of rainbow trout (Oncorhynchus mykiss) embryos was studied by light and electron microscopy at four different developmental stages. Embryos were examined during gill arch formation (stages 22-24, Vernier, '69), development of the gill filaments (hatching stage), and formation of gill lamellae (stage 36).

Chromosome study of Oncorhynchus mykiss kamloops

Aquaculture, 1990
Abstract Rainbow trout of the Czechoslovak strain “PdD 66” which has been suggested to originate from Oncorhynchus mykiss subspecies kamloops Jordan, 1892 (Kamloops Lake, British Columbia), were karyotyped to test and verify their reported origin cytogenetically.

The use of DNA SCAR markers for differentiation of Kamchatka mykiss (Parasalmo (Oncorhynchus) mykiss)

Doklady Biological Sciences, 2014
The species Parasalmo ( Oncorhynchus) mykiss (Kamchatka mykiss; mykiss) belongs to salmonid fish (Salmonidae family) and has a complex population structure; it is widely spread and characterized by a high rate of microevolution. Mykiss has been exten sively studied by many researchers for a long time.

Phosphofructokinase from Liver of the Rainbow Trout, Oncorhynchus mykiss

Archives of Biochemistry and Biophysics, 1993
Phosphofructokinase (PFK) from liver of the rainbow trout Oncorhynchus mykiss was purified to homogeneity with a recovery of 35% of total activity. The purified enzyme was a homotetramer with a native molecular weight of 297,000 +/- 16,000 and a subunit M(r) of 76,000 +/- 3000.

Residues of clenbuterol in tissues of the rainbow trout (Oncorhynchus mykiss)

Veterinary Research Communications, 1994
There have been many studies on the efficacy of beta 2-adrenergic drugs as feed additives but no data are available at present on the use of clenbuterol in fish production. To evaluate the residues of clenbuterol in tissues of fish, 50 trout (Oncorhynchus mykiss) were fed for 21 days on a fish feed containing 5 ppm of the drug.

Peripheral serotonin dynamics in the rainbow trout (Oncorhynchus mykiss)

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2007
Serotonin (5-hydroxytryptamine, 5-HT) occurs in a wide range of tissues throughout the body of the rainbow trout. Results reported here indicate that the main peripheral sources of serotonin are the intestinal tract and the gill epithelium (levels above 1500 ng/g). The high intestinal serotonin concentration is mostly due to serotoninergic nerve fibres,

Monoclonal antibodies to lymphocytes of rainbow trout (Oncorhynchus mykiss)

Fish & Shellfish Immunology, 2003
Monoclonal antibodies (Mabs) to lymphocytes of rainbow trout have been developed by immunisation with synthetic peptides, prepared from selected parts of the alpha- and beta-gene sequences of the T-cell receptor (TCR). Mab 1C2 (TCR beta immunisation) identified lymphocytes in blood (11%), spleen (18%) and in thymus (9%) in flow cytometry analysis (FCM).
