Abstract
Stocking density is considered one of the important factors affecting fish growth. But, information related to impact of stocking density on growth performance of androgen-treated monosex tilapia population during cage culture under the ecological conditions of Gangetic plains in West Bengal, India is limited. The aim of our study was to compare the growth potential of control and hormone-treated, sex reversed tilapia at various stocking densities and to determine an ideal stocking density for cage culture of monosex fish. Control and hormone treated fish were stocked separately in mesh cages at different stocking densities (1, 5, 10, 15, 25, 50, 75 and 100 fry / m3) and it was found that the highest growth was observed for the 50 fish / m3 groups for both the control and hormone treated categories. More over, the monosex androgen treated population showed much higher growth potential for all the density groups compared to the corresponding mixedsex population. Thus, cage culture of hormone treated monosex tilapia at a density of 50 fish / m3 can be considered ideal for augmented production of the fish under Indian context.
