Abdurahiman, K P and Zacharia, P U and Nayak, T H and Mohamed, K S (2007) Trophodynamics of the Spotfin Flathead Grammoplites suppositus (Troschel 1840) from the Southeast Arabian Sea. Asian Fisheries Science , 20 (2). pp. 125-143.
The dietary habits of the spotfin flathead, Grammoplites suppositus which inhabits the southeast Arabian Sea was studied. The stomach contents of 581 specimens were analysed between September 2001 and May 2002. G. suppositus preyed primarily on crustaceans. The most important preys were benthic crabs and penaeid prawns, and fishes were next in rank. During premonsoon, fishes and crustaceans were equally important, whereas in monsoon and postmonsoon benthic crabs and penaeid prawns were the predominant prey. There were significant (p<0.001) ontogenetic changes in the diet. Smaller length groups (<165 mm) ate mostly the flatfish Cynoglossus macrostomus and other fishes, whereas individuals of larger length groups (>165 mm) ate crustaceans such as the benthic crabs, penaeid prawns, the paste shrimp, Acetes indicus and the mantis shrimp, Oratosquilla nepa.
