Two completely randomized experimental designs were conducted to investigate the effect of different levels of dietary Ca (0.95%, 1.21%, 1.41% and 1.61%) and K (0.72%, 0.9%, 1.1% and 1.3%) on some growth indices, body biochemical composition and some whole body elements in rainbow trout fingerlings in a culture system. Tow basic diets with 0.95% Ca and 0.72% K were prepared and with CaCO3 for experiment І and K2CO3 for experiment ІІ, other dietary treatments were built. In initiation of each experiments, 25 pieces of rainbow trout fingerlings (12.18 ± 0.04 and 15.60 ± 0.05) introduced in each experimental units respectively, and were fed with dietary treatment ad libitum two times daily at 9:00 and 15:00 for a 8 week period. It was resulted that different levels of inorganic dietary-Ca in diets, had not significantly affec.. View More»
