Present study is based on the examination of gut contents of 422 fishes, collected from Mumbai coast, Maharashtra. Based on index of preponderance values, diatoms (60.97%) and zooplankton (25.79%) were found to be the major components of the food. Month wise gut content showed that among the diatoms Cosinodiscus spp. (17.43%), was most dominant followed by Fragilaria oceanica (14.34%) and Pleurosigma spp.(10.86%), in the zooplankton copepods were the most occurred throughout the year, contributing maximum in the May (15.94%) and least in January (4.79%). Gastro somatic index in males and females ranged from 0.80 to 1.41 and 0.72 to 1.60 respectively with there is no significance difference between males and females (P >0.05). Month wise feeding intensity was observed to be highest, for both sexes during May and length wise in smaller size groups (120-129 mm). Not Available |
