An analysis of the chromosomes of the rainbow trout, <i>Salmo gairdneri, </i>revealed one triploid individual among 18 specimens examined. The diploid specimens possessed 60 chromosomes, whereas the single triploid possessed approximately 90. Suppression of the second meiotic division followed by fertilization of the unreduced oocyte is the

Inorganica Chimica Acta, 1985
Two forms of hepatic metallothionein were isolated and purified from rainbow trout injected intraperitoneally with cadmium chloride. Both forms showed similarities with mammalian metallothioneins, had a high cystein content (30 mol%), and were void of aromatic amino acids and histidine. The molecular weight was estimated to be about 6000 dalton for the

A pepsinogen from rainbow trout
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19831. A pepsinogen, Ia on the basis of its electrophoretic mobility, from rainbow trout stomach, has an optimum pH near 2 for activation. 2. The cognate pepsin is denatured at pH values above 7, in contrast to the zymogen, which is slightly more alkali-stable. It has an optimum pH of 3 for proteolysis of denatured hemoglobin. 3.

Abstract Astaxanthin is the major carotenoid pigment responsible for the pink colour in the flesh of wild rainbow trout, while both astaxanthin and canthaxanthin are used for pigmenting farmed trout. Astaxanthin is reduced to zeaxanthin and canthaxanthin to β-carotene by analogous metabolic routes.

Rainbow trout red cells in vitro
Comparative Biochemistry and Physiology Part A: Physiology, 1985Washed rainbow trout erythrocytes incubated at 14 degrees C in Eagle's minimal essential medium and Cortland saline displayed sharp reductions in volume and water content, nucleoside triphosphate, K+ and Cl- concentrations. Mg2+ and, to a lesser extent, Na+ concentrations increased.

Tissue carboxylesterase activity of rainbow trout
Environmental Toxicology and Chemistry, 1999AbstractThe activity of carboxylesterase (CaE), a class of nonspecific serine hydrolases, was evaluated in vitro in tissues and microsomes of rainbow trout and compared to esterase activity in rats, other fish species, and embryo to adult life stages of trout. Trout gill and liver microsomes exhibited substantial CaE activity and limited variation over

Production of androgenetic diploid rainbow trout
Journal of Heredity, 1985Haploid androgenesis was induced in rainbow trout (Salmo gairdneri) when eggs were irradiated with 60Co gamma radiation prior to fertilization. Diploidy was restored to the androgenetic haploid zygotes by suppression of first cleavage division using hydrostatic pressure.

Erythrocyte volume distribution in rainbow trout
American Journal of Veterinary Research, 1985SUMMARY 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, 1991AbstractWe 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, 1992Neuropeptide 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 ...
