Giant gourami, Osphronemus goramy, Lacepède (1801) culture of different production systems has significantly improved fish production yields and food security in Indonesia. This study analyzed nutrient loadings and characteristics farms of giant gourami in the floating cages in Lake Maninjau.Estimates of C, N and P loads from floating cages, feeding rate, feed efficiency and gross yield a presented in this study were made from production records, production cycle, harvests, daily feed and fish mortality records were collected from fish farmers for 20 units. Elemental composition analysis of feed and fish were determined by standard methods of the AOAC. The data on the C, N and P composition of fish and feed were combined with stocking and harvesting information and used in mass balance equations to estimate C, N and P loads from floating cages.Apart from estimating C, N and P load from the floating net cages released into the water bodies. Stocking density rates for each cage are recorded, for determine their daily feeding rates. Then, fish production records were analyzed to determined nutrient wastes from giant gourami fish farming. For estimating stocking density in aquaculture fish cages, we used equation Schmittou.
