Abstract
Asian seabass (Lates calcarifer) is one of the important and commercial species. Due to its fast growth, easy reproduction, high salt tolerance and ability to accept formula food, it has been considered as one of the best farmed fish in the world in recent years This fish is cultivated in different ways. The present research was conducted in order to investigate the effect of density on the growth indicators and the survival rate of Asian seabass fry in 9 round assembled tanks with a diameter of 10 Meter and a height of 2 meters and a volume of 150 cubic meters of water for 120 days. In this research, the number of 29,500 pieces of Asian seabass fry with an average weight of 42.00±0.03 grams in a completely randomized design in 3 treatments and 3 replications with densities of 15, 20 and 25 pieces per cubic meter respectively in treatments A, B and C are stuocked. 44% were fed with special salmon pellet food at the rate of raw breeding. The results showed that the highest specific growth rate was 6.3±0.02, survival was 93.56±3.22, and the highest final weight was 800.10±0.40 in treatment A, and the highest food conversion ratio was 1.6 in treatment C with the lowest weight. The final was recorded. This study showed that the density has a significant effect on the growth and survival indicators of Asian seabass fry, so that the stocking density of 15 pieces per cubic meter in the recirculation system for seabass has the highest growth and is recommended.
