Variation of muscular fiber diameter in trout, depending on species and age
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2010, Vol 3, Issue 5
Abstract
To assess the quality of rainbow and brook trout meat we considered that its opportune to make some histological investigations about muscle fiber diameter. The research was done using fish of one, two and three years old. Muscle was sampled systematically and differentiated by age and body mass and the results were statistically analyzed. The comparative statistical analysis reveals significant differences between the two species of trout and according to age is found a different evolution of body mass and implicitly of muscle fiber diameter. We also calculated the phenotypic correlation coefficients (r) between the two traits and the obtained values indicated a correlation degree with different intensity depending on body weight. Based on histological examination of rainbow and brook trout muscles the conclusion that emerges is whatever of species, the muscle fiber fineness has a significant trend according to the dynamics of growth and age.
