Effect of formulated feed on the biochemical composition of cultured shrimp, Penaeus monodon (Fabricius, 1798)
K Immaculate Jeyasanta, Jamila Patterson
Experimental feed were formulated using locally available ingredients and commercial feeds were bought from market and the quality were studied. An experiment was conducted using both the feeds later these were fed to P. monodon and finally compared whole body biochemical composition of shrimp fed by different feeds to assess the quality of the feeds on biochemical cultured shrimp composition. The biochemical composition of the experimental feed fed shrimp showed higher protein, lipid, carbohydrate, fiber, ash and less moisture than commercial feeds. Amino acids composition of shrimps showed higher amount of essential amino acids and fewer amounts of non-essential amino acids and it was high in laboratory made feed. Shrimp meat had significantly higher proportion of unsaturated fatty acids, lower proportion of saturated fatty acids and their content were in the following trend that shrimps fed with laboratory made feed > control feed. It was evident from this study that the crustacean nutritive profiles are influenced by the changes in the nutritional composition of the diet and by changes in the dietary sources.
