Effect of different stocking density on growth and survival of monosex tilapia cage culture in Perumpallam Reservoir, Tamil Nadu

The study was carried out to assess the effect of stocking density on the growth and survival of GIF Tilapia (Oreochromisniloticus) for a period of 90 days from June to August 2016 in the Perumpallam reservoir, Erode District, Tamil Nadu. Uniform size tilapia fingerlings with an average weight of 11 g were released in three different cages with the stocking density of 40 50 and 60/m³. Fishes were fed with a commercial floating pellet feed containing 28% protein to observe the growth of the tilapia in cages. The present study demonstrated that 40 fish/m³ was the best stocking density in terms of growth, food conversion ratio, and survival for tilapia culture in the cage culture and the experiment revealed that the low stocking density in the cage showed better growth than the high stocking density.
