The hybrid grouper is a hybrid of tiger grouper (Epinephelus fuscoguttatus ♀) and giant grouper (E. lanceolatus ♂). It is resistant to high water temperatures, and it is possibility as a new aquaculture breed to replace fish species that are frequently damaged by high water temperatures. In our previous study, as a result of confirming the growth effect by water temperature as the intermediate growing condition of the hybrid grouper, the growth rate was high at high water temperatures of 28 and 32℃. However, when considering economic feasibility such as water temperature heating, 28℃ is effective for aquaculture water temperature. In this study, the growth effect of the hybrid grouper was confirmed according to the stocking density as the intermediate growing condition.
The hybrid grouper used in the experiment had an average body weight of about 70 g, and each 1 ton of tank was stocked with 50 (3.5 kg/m<sup>3</sup>), 100 (7.0 kg/m<sup>3</sup>), 150 (10.5 kg/m<sup>3</sup>), and 200 fish (14.0 kg/m<sup>3</sup>). And each tank was supplied with running sea water at approximately 30 psu salinity, and the temperature was kept at approximately 28℃. The twice repeated experiment was performed. The growth rate and survival rate were confirmed by measuring the body weight and total length of fish in each tank at 2 weeks intervals for 14 ... 전체 초록 보기
