Values are expressed as mean ± SD. IW, initial weight; FW, final weight; LWG, live weight gain; SGR, specific growth rate; TB, total biomass; FCR, feed conversion ratio; PER, protein efficiency ratio; SR, survival rate; HSI, hepatosomatic index; VSI, visceral somatic index; GSI, gonadosomatic index; EFR, egg fertilization rate; OD, ovipositor diameter; HR, hatching rate; and OT, ovulation time. Different superscript letters in each row indicate significant differences ().
