Reproductive study of a fish is an important for fishery resources and conservation management. Their provide information on the basis for early life history and oriented studies. In the present investigation clearly showed that the assessment of size at maturity, fecundity, spawning behaviour and capacity of reproductive in Pterois volitans. The graphical representation shows there is the intimate relationship between the length of the ovary and its relativem weight. On the graphical representation, in the month of August every year the high values of gonad weight and fecundity were concluded. The gonad weight (GW) can be expressed as F=9387.9GW+34026 with an r2 value of 0.5723. It was recorded for significantly different. The GSI values of female P. volitans have also shown similar increasing trend associated with histological changes. A GSI value increase with corresponding histological changes was also noticed in lion fish P. volitans.
