Abstract/Description: | The food habits of little tunny Euthynnus affinis caught by hooks and line off Chennai and Cuddalore in Tamil Nadu were studied from December 2011 to August 2012. A total of 358 samples were collected from both the centres and gut contents were analysed. Almost 42% of the guts were full and 22% were found to be either quarter full or with traces of food contents. About 35% of the guts were empty. Index of relative importance (IRI) was calculated for the prey items. Crustacean larvae (91%) were dominant among the gut contents, followed by fishes (4%) and molluscs (2%). Among the crustacean larvae, brachyuran megalopae and crablets formed about 45% while the stomatopod alima larvae formed 21%. Phyllosoma larvae of scyllarid lobsters and pueruli larvae of spiny lobsters were also found among the identified crustacean larvae. |
