In this study, capacity vacuous index (CV) and food preference (Fp) calculated for this fish.
The study of stomachs showed that stomach of 44 fish were full, 27 semifull and 524 were empty. CV was obtained 88.4 and Fp for crustacean (55.6), fishes (44.3) and molusca (1.4).
In particularly study, Fp calculated for crab (54.0), squilla (23.2), shrimp (20.2) and lobster (2.5). Ultimately, in this survey was found that this fish possibly is fast feeder and crustacean to be omposed their main food. Among crustacean, crab is main food.
