Erythrocyte volume distribution in rainbow trout

American Journal of Veterinary Research, 1985
SUMMARY Reference mean corpuscular volume and volume heterogeneity values for erythrocytes of 23 rainbow trout were measured, using an electronic particle counter, and were analyzed, using a particle-size analyzer and microcomputer. The mean (± sd) erythrocyte count was 1.5 × 106 ± 0.16 × 106 cells/µl, the mean corpuscular volume was 346 ± 25 fl, and ...

Genetic analysis of androgenetic rainbow trout

Journal of Experimental Zoology, 1991
AbstractWe analyzed a number of genetic characteristics in androgenetic rainbow trout (Oncorhynchus mykiss) and their progeny. The androgenetic progeny of individual androgenetic males appeared genetically identical to each other based on eight enzyme loci. Their viability was no higher than that of androgenetic progeny of outbred males.

Rainbow trout (Oncorhynchus mykiss) neuropeptide Y

Peptides, 1992
Neuropeptide Y (NPY) has been isolated from brain extracts of the rainbow trout (Oncorhynchus mykiss) and subjected to structural analyses. Plasma desorption mass spectroscopy estimated the molecular mass of the purified peptide as 4303.9 Da. Automated Edman degradation unequivocally established the sequence of a 36 amino acid residue peptide as: Tyr ...

A Rainbow Trout Lectin with Multimeric Structure

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
A novel lectin has been identified in rainbow trout serum and plasma. The lectin binds to Sepharose (an agarose polymer) in a calcium-dependent manner. Glucose, N-acetyl-glucosamine, mannose, N-acetyl-mannosamine, L-fucose, maltose and alpha-methyl-mannoside are good inhibitors of this binding, whereas glucosamine and D-fucose inhibits to a lesser ...

Utilization of Dietary Urea in Rainbow Trout

Annals of Nutrition and Metabolism, 1983
Experiments were conducted to examine the potential utilization of dietary urea by rainbow trout. A control diet and two diets supplemented with 1 and 3% of urea were fed to fish. Postprandial levels of urea and ammonia in blood plasma, and postprandial excretion of these metabolites were followed during 24 h.

Viral haemorrhagic septicaemia virus multiplication and interferon production in rainbow trout and in rainbow trout × brook trout hybrids

Fish & Shellfish Immunology, 1994
Abstract Rainbow trout ( Oncorhynchus mykiss ) susceptible to Viral Haemorrhagic Septicaemia (VHS) Virus type 1 and rainbow trout × brook trout ( Salvelinus fontinalis ) triploid hybrids were challenged with VHSV by either immersion or i.p. injection of the virus.

Methemoglobin in erythrocytes of rainbow trout

Comparative Biochemistry and Physiology Part A: Physiology, 1971
Abstract 1. 1. The proportion of hemoglobin carried as oxidized (met-) hemoglobin was found to vary from 2·9 per cent in a wild stock to 17 per cent in a hatchery stock of rainbow trout. 2. 2. Hypoxia, anemia and the reticulocyte percentage (and consequently cell age) had little effect on the methemoglobin content. 3. 3.

Habitat shifts in rainbow trout: competitive influences of brown trout

Oecologia, 1987
We compared habitat use by rainbow trout sympatric (three streams) and allopatric (two streams) with brown trout to determine whether competition occurred between these two species in the southern Appalachian Mountains. We measured water depth, water velocity, substrate, distance to overhead vegetation, sunlight, and surface turbulence both where we ...

Avoidance of aluminum by rainbow trout

Environmental Toxicology and Chemistry, 2000
Abstract Aluminum is the principal toxicant in fish in acid waters. The ability to avoid Al, particularly at low concentrations, would confer a considerable ecological advantage, but previous research into avoidance of Al has produced mixed results.

An Epizootic Among Rainbow Trout

The Progressive Fish-Culturist, 1953
Abstract An epizootic among rainbow trout (Salmo gairdnerii) in a private trout farm, resulting from a species of Ichthyosporidium that caused very high mortality rates in all ages of trout, reported from the State of Washington.
