Possibility of rearing silver bream (Sparidentex hasta) in the earthen pond was experimented using 2 types of available artificial trout feed (FFT and GFT1). The experiment was carried out in 2 phases in Shahid-Kiani Extension Shrimp Farm in Chowibdeh Shrimp Site-Abadan Southern Iran, and earthen ponds with 0.25 ha. Area were used for both phases of the study. Juvenile fish of 3.2 g initial weight with the density of 9324 ind./ha. Were stocked for 196 days in the first phase. The initial weight, stocking density and rearing period of the fish in the second phase were 108.60 g, 9800 ind./ha. And 237 days respectively. Maximum amount of WG, FCR, PER and SVR of the fish in the first phase of the study were 100.12 g, more than 6, 0.38 and 55.32% respectively. WG and SR of the fish in the second phase respectively were 417 g and 20.74%. The Salinity of pond water was in the range between 9 and 22 ppt, and the water temperature was between 8.3 ֯C (mid December morning) and 34.8 ֯C (early September afternoon) during the study. Also water pond PH was recorded in the range of 8.65 (morning) and 7.83-9.20 (afternoon) in the study period. Results of the study showed that growth rate of the fish was increased with the increasing of the water temperature, but it showed slow rate or ultimately stopped when the temperature passed 25 ֯C. Also results indicated that artificial feeds of FFT or GFT1 are not accepted as economically feeds for this species to be cultured.Pages
