The present invention relates to an aquaculture system of farming Asian Seabass in multiple cages in inland aquaculture ponds. A protocol is developed wherein, fish more specifically Asian Seabass is cultured stage/size wise in a multiple cage culturing system. The multiple cage culturing system comprises of plurality of distinct floating nursery cages and grow out cages, with selected floating grow out cage having raised hand rails. All these cages can also be provided with individual outer cages for additional protection and placed at different locations with the same open earthen pond. The different cages are used at different stages of growth and development. Depending on the rate of growth of fishes and the size they are continuously graded according to their size and shifted to different grow out cages thereby fishes of same sizes are available in a specific cage, which achieves to eliminate cannibalism and competition among various size range suffered in prior art.
