Rao, A Chandrasekhara | Krishnan, L
Changes in biological indices (gonadosomatic index GSI, hepatosomatic index HSI and condition factor) and biochemicalcomposition of body tissues and serum, associated with ovarian development were examined in Epinephelus diacanthussampled for two years. GSI, HSI and Condition factor values increased with the maturation of gonads. Mobilisation ofbiochemical constituents from somatic tissues to the gonadal tissues with the maturation of the ovary was noticed. Highestprotein percentage was in stage III (24.81%) ovary. The total lipid percentage of the ovary showed a gradual increase fromStage I (6.56%) to Stage III (13.48%). Total cholesterol showed a steady declining trend and carotenoid levels of the ovaryshowed a positive relationship with ovarian maturation. Ash content of the ovary increased from stage I (0.82%) to stage III(1.20%).
