In the present study stocking density, feed ration on performance and environmental nutrient loading from culture of tiger shrimp (penaeus monodon) fed by check tray method was assessed by 120 days outdoor culture experiment. During the experiment two commercially available shrimp diets CD1 and CD2 were evaluated by three different stocking densities 15, 30, and 45 nos/m2 with two feeding ratio 10 and 15% body weight. Maximum growth, FCR and SGR were obtained in tanks stocked with 15 nos/m2 with 10% body weight feed ration in CD1 diet fed groups. The performance parameters of CD2 diet also more or less similar to CD1 diet. On the analysis of nitrogen and phosphorus retention and loss in outdoor culture experiment nitrogen, phosphorus consumption and retention was more in culture tanks stocked with maximum stocking density 45 nos/m2 likewise total nitrogen and phosphorus loss also maximum in 45 nos/m2 stocked tanks. More or similar trend noticed in 15% feed ration. Commercial feed CD2 also, a similar variation in nitrogen and phosphorus consumption, gain, retention and loss as percentage of feed were recorded for both 10 and 15% body weight. But the overall values were high for commercial feed CD1 when compared to CD2 diet.
