Effects of Different Salinities on Growth, Feeding Performance and Plasma Cortisol Level in Hybrid TGGG (Tiger Grouper, Epinephelus fuscoguttatusx Giant Grouper, Epinephelus lanceolatus) Juveniles

Abstract The hybrid TGGG, tiger grouper Epinephelus fuscoguttatusx giant grouper, Epinephelus lanceolatus has a high resistance towards extreme conditions due to its genetic improvement. This study investigated the effects of different salinities on growth, feeding performance and plasma cortisol level in TGGG juveniles. The TGGG juveniles were acclimatized and subjected to 7 different water salinities at 5, 10, 15, 20, 25, 30 and 35 part per thousand (ppt
