EVALUATION OF GROWTH AND PRODUCTION PERFORMANCE OF SILVER POMPANO, TRACHINOTUS BLOCHII IN HDPE LINED POND
The silver pompano, Trachinotus blochii (Lacépède, 1801), also known as Snubnose Pompano. It is considered as a promising species for coastal aquaculture and mariculture because of easily adapts to the culture environment. It readily accepts formulated feeds and has a rapid and uniform growth rate as compared to other farmed fishes.
Growth, survival and production performance of silver pompano, Trachinotus blochii, (Lacépède, 1801) were evaluated in a HDPE lined pond in Mandapam Centre for Sustainable Aquaculture of Tamil Nadu Dr.J.Jayalalithaa Fisheries University. A total of 51 fingerlings of silver pompano (13.7 cm mean length and 46 g mean weight) were stocked in a (50 m2) pond. Water quality parameters were also recorded during experimental periods. Fishes were fed with commercial extruded floating pellet feed containing 44 % crude protein and 7 - 12 % crude fat.
After 110 days of culture, 7.21 kg of silver pompano were harvested. The calculated survival rate, mean body weight, and FCR are given in Table. The results revealed that production of silver pompano was found to be technically and economically feasible in HDPE line pond.
The present study clearly indicated that the growth of silver pompano under HDPE lined pond is promising one and considered as a promising species for coastal aquaculture.
