Etroplus suratensis
 
Description Based on chemical composition of feed and body constituents, food utilization at maintenance and different production levels was estimated. On theoretical derivations, 175, 450 and 650 kcal/kg super(0.8)/week represented the maintenance, optimum and maximum levels. Utilization of gross energy at maintenance level was 35.91% which was lower than the values reported for common carp, grass carp and trout. Percent available energy at maintenance level was 48.75 of the gross energy offered to the fish. Utilization of gross protein energy at maintenance level was 33.97% which was equivalent to the rate of utilization of gross total energy. The optimum feeding level for effective growth under laboratory conditions was 10% live body weight/day
