Trophic ecology of eight species of nemipterid fish including Nemipterus mesoprion, N. hexodon, N. nemurus, N. nematophorus, N. tambuloides, N. peronii, N. furcosus and Scolopsis taeniopterus were studied to investigate their diet composition and trophic relationships between them. Our findings revealed that they were specific predators feeding mainly on shrimp and fish. N. nemurus and N. tambuloides were the most piscivorous species of them all, and N. mesoprion was a specific shrimp predator. In general, there were highly significant differences of stomach fullness (FL) and average number of food item (AF) among species (P<0.01). Size classes significantly affected FL of five species including N. nematophorus, N. mesoprion, N. nemurus, N. tamboloides and S. taeniopterus (P<0.05) and AF of four species including N. nemurus, S. taeniopterus, N. hexodon and N. Peronii (P<0.05). Sex was an influential factor on FL of N. mesoprion (P<0.01) and N. preonii (P<0.05) and AF of N. hexodon (P<0.05) and N. peronii (P<0.05). Maturity stages significantly affected FL of N. mesoprion (P<0.01) and S. taeniopterus (P<0.05) , however, they had no impact on AF of any species (P>0.05). The coexistence of these species in the bottom waters of this habitat requires partitioning of available food resources.
