Abstract
Condition factor ( K ), gonadosomatic index, ( IGS ), hepatosomatic index ( IHS ) and fat visceral index ( IGV ) were estimated and the biochemical composition in different tissues of wild leopard grouper broodstock was determinate too, in order to evaluate them along a reproductive cycle and see the relationship of these changes with respect to the water temperature and photoperiod in the sampling area. 187 brooders were caught, 146 females and 41 males in the Gulf of California, Mexico. Significant differences ( P < 0.005) in the IGS , IHS and IGV but not for K were observed. Significant changes ( P < 0.05) were also observed in most of the biochemical parameters, being the highest value during the spawning stage, whereas the lowest occurred during the resting stage. Significant correlations ( P < 0.05) between all estimated indices and biochemical parameters were observed, while only significant correlations ( P < 0.05) between the IGS and IGV with respect to water temperature.
