Fast-start muscle dynamics in the rainbow trout Oncorhynchus mykiss: phase relationship of white muscle shortening and body curvature.

Skeletal muscle deformation in the lateral muscle of the intact rainbow trout Oncorhynchus mykiss during fast start maneuvers.

Although there is an extensive body of information on the kinematics of the fast start response in teleosts, there is little information on the deformation of the skeletal muscle which produces the changes in body position during a fast start. This study presents preliminary information on the determination of skeletal muscle deformation with implanted ultrasonic dimension gauges in the intact ...

Proteomic analysis of muscle tissue from rainbow trout (Oncorhynchus mykiss) fed dietary β-glucan

The aim of this study was to examine the changes in muscle proteome of the rainbow trout fed dietary β-glucan. The experimental diets contained 0 (control), 0.1% and 0.2% β-1,3/1,6 yeast glucan. First, feeding larvae were fed to apparent satiation nine times per day with their respective diets over two months. The percentage of body weight gain and feed efficiency of fish fed 0.2% diet was sign...

Parvalbumin expression in trout swimming muscle correlates with relaxation rate.

Rainbow trout (Oncorhynchus mykiss) display longitudinal and developmental shifts in muscle relaxation rate. This study aimed to determine the role of variations in parvalbumin content in modulating muscle relaxation. Parvalbumin is a low molecular weight protein that buffers myoplasmic Ca2+ and enhances muscle relaxation. In some fish, longitudinal variations in muscle relaxation have been lin...

Short communication:The comparison of fatty acids, fat-soluble vitamins and cholesterol in the muscle of wild caught, cage and pond reared rainbow trout (Oncorhynchus mykiss W., 1792)

Caspian Sea gamarus (Pontogammarus maeoticus) as a carotenoid source for muscle pigmentation of rainbow trout (Oncorhynchus mykiss)

The red coloration of rainbow trout muscle is an important quality criterion. Duplicate groups of rainbow trout (Oncorhynchus mykiss; initial weight of 200±10g) were fed diets either supplemented 0 (control), 0.5, 2, or 4%, of the Caspian Sea gammarus (Pontogammarus maeoticus) respectively as a prospective alternative carotenoid source. The feeding trial lasted for 39 days. No significant diffe...
