Sampling was done with trawl nets and expected nets. 438 specimens of the Malabar trevall (C. malabaricus) were selected for dietary examination. Results of descriptive bioassay data indicated that the maximum total length was 365 mm (in May) and the minimum total length was 140 mm (in September) and the maximum weight was 534.5 g and minimum was 57.8 g. During the study period, the mean total fish length was 261 ± 18.41 mm and the mean fish weight was 191.78 25 25.35 g. The GASI index showed a peak feeding in June.
