Abstract

Studies on the growth of Lates calcarifer cultured in coastal ponds and net cages in the three different places at Tuticorin showed an increase of 16.2-23.2 mm/ 18.6- 53.2 g/ month at Karapad, 21.1-29.8mm/19.3- 36.3 g / month at Veppalodai in coastal ponds and 21.6-32.4 mm/ 31.4-55.0 g / month in a net cage in the Tuticorin Bay. The growth in Karapad pond, where supplementary feed was provided was better than in Veppalodai pond. The highest growth rate was obtained in net cage culture at Tuticorin Bay. Length-frequency analysis of samples from commercial catch reveal a faster growth in the wild than in the culture systems. The better growth in the brackishwater culture and in the wild is attributed to the lower salinity and better live feed availability in brackishwater. In the pond system, the growth can be improved by maintaining proper water exchange so as to maintain the salinity equivalent to open sea/bay/ brackishwaters and by providing supplementary feed.
