Abstract:Stomach contents of hairtail(Trichiurus japonicus) were collected from the East China Sea region from Dec. 2002 to Nov. 2003. The dietary compositions of hairtail were analysed in this paper. The results showed that fishes were the dominant species among all the composition, with IRI of 7034.95, which occurred in 65.34% of the studied hairtails and accounted for 13.68% of component individuals and 93.99% of component weight. The IRI of crustaceans was 1527.99,with 18.41%of the occurrence in the studied hairtails, and accounting for 80.11% of component individuals and 2.87% of component weight. Listed in the last order was cephalopods, with IRI of 39.42 , whcih occurred in 7.58% of the studied hairtails, and represented 2.13% of component individuals and 3.07% of component weight. Among 62 species of diet compositions, fishes occurred 38 species, crustaceans 14 species, cephalopods 8 species. The dominant species compositions were Trichiurus japonicus, Euphausia sp., Mysidacea sp., Psenopsis anomala and Benthosema pterotum.
Keywords:Hairtail  food habit  the East China Sea
