The influence of season and levels of dietary lipid on growth performance and lipid composition in rainbow trout Parasalmo mykiss (Walbaum, 1792)

详细

We studied the growth performance and lipid composition of liver, muscles and visceral fat in rainbow trout Parasalmo mykiss (Walbaum, 1792) and the diets used in its cultivation during the spring-summer season. The differences in dietary lipid composition determined modifications in the biochemical composition of tissues of rainbow trout and had an effect on the weight and growth rate of the fish. Trophic and seasonal factors also had their influence on the studied parameters. The degree of influence depended on the functional characteristics of tissues and organs of rainbow trout.
