Abstract
Growth, survival and production performance of hatchery produced silver pompano, Trachinotus blochii, (Lacépède, 1801) fingerlings were evaluated in a brackishwater pond in Anthervedi, East Godavari District, Andhra Pradesh, India. A total of 3,400 fingerlings of silver pompano (30.59 ± 0.24 mm mean length and 2.00 ± 0.04 g mean weight) were stocked in a one acre pond (0.4047 ha) with salinity of 8 ± 1.2 ppt. The salinity gradually increased to 24 ± 1.8 %0 during the farming period due to high saline intake water. Fishes were fed with extruded floating pellet feed containing 50 to 30% crude protein and 10 to 6% crude fat. After 240 days of culture, 1,305 kg of silver pompano were harvested. The survival rate was 91.32%. Mean length of the harvested fishes was 296.88 ± 6.27 mm and mean body weight 464.65 ±10.25 g. The absolute and specific growth rate obtained were 1.93 g day-1 and 2.27% per day respectively with an FCR of 1:1.83. The results revealed that farming of T. blochii in brackishwater pond is technically feasible.
