Tilapia, now the second most farmed fish in the world, has played an important role in the growth of aquaculture sector and will continue in the future also. Knowing the aquaculture importance the culture of genetically improved different strains of Nile tilapia is promoted by the central and state government of India. This study examined the growth performance of monosex Nile tilapia (Oreochromis niloticus) juveniles at various stocking densities in grow out ponds. The study was conducted in farm ponds with two different high stocking densities (20000 nos./1.5 acre and 10000 nos./1 acre) with the average stock size of 10g. The fishes were fed with commercial pellet feed (35% crude protein, 4% fat and 7% fibre) at 5-7 % of their of body weight. In a six month period of culture the average final weight obtained was 300 g in pond 1 and 330g in Pond 2. The growth related parameters of all male Tilapia was recorded in this study was presented in Table 1. Based on the results of growth performance and yield from this study, the all male Tilapia culture has been found to be a suitable candidate species for aquaculture.
