Abstract
The objective of present study was to determine the nutrient contents of natural feed of tiger grouper (Epinephelus fuscoguttatus (Forsskål, 1775)) especially for crude protein and amino acidscontent. Five types of feed which have been commonly used by farmers were tested in this study, namely shrimp (Mesopodytes sp.), Love Larva[sup]®[/sup]pellet, EP2[sup]®[/sup]pellet, anchovies (Stolephorus spp.) and tilapias (Oreochromis mossambicus (Peters, 1852)). The result showed that the average content of crude protein were 46.51% in shrimp, 50.16% in pellet Love Larva[sup]®[/sup], 55.00% in pellet EP2[sup]®[/sup], 52.54% in anchovies and 45.16% in tilapias. The result also showed that EP2[sup]®[/sup]pellet comprised significantly higher protein content that other diets (p<0.05). The major essential amino acid in all of five feed types were Lysine (2.2 to 3.7%), Leucine (2.5 to 3.6%) and Arginine (2.4 to 3.4 %). The major non essential amino acid in all five feed types were Glutamic acid (range from 4.7 to 6.5%) and Aspartic acid (range from 3.1 to 4.7%). Pellet EP2[sup]® [/sup]had highest amino and Aspartic acid compared to other diets whereas higher Tyrocine was detected in shrimp.
