Estimates of gut contents are important prerequisites for fishery biological investigations. Food and feeding habits of Mugil cephalus of Kayamkulam estuary (902’-9019’N latitude and 76026’-76032’ E longitude) were observed on 160 specimens collected at monthly intervals during May-Dec.2010. The values of RLG varied between 2.1-3.35 indicating the omnivorous feeding habit of the fish. Feeding intensity analysis revealed the predominance of poorly fed fishes in the estuary. Proportion of actively fed fishes was maximum (33.34%) during October. Gut contents of the fish comprise diatoms, decayed organic matter, fresh and decomposing algal matter together with sand and mud. Diatoms contribute 58.94% of the total gut contents.
