Groupers are high price and very popular food fish in Asia. With the economic development of oversea Chinese, the consumption of different grouper species is increasing. Low survival of grouperthe fingerlings, mainly caused by virus infection and cannibalism, retard the progress of grouper culture. In this study, the
fingerling will be cultured with standard operation
procedure in a closed semi-recirculated system. To solve the high cannibalism problem of rearing tiger grouper fingerling, increasing feeding frequency, stocking density, photoperiod, sorting frequency and improving weaning technique, feed size and feed attractant will be adapted to improve survival of white body larvae to 3 inche fingerling. This study is deigned to find optimal stocking density and size in the rearing period. To prevent the virus break out in the period, a well controlled environment and pretreated water supply will be provided to produce high quality fingerlings. |
