According to the catch samples from the investigation of fishery resources monitoring in the East China Sea from December 2002 to November 2003, the stomach contents of hairtail were analyzed. The results showed that the food composition of the fish was mainly fish (IRI = 7034.95), the occurrence rate was 65.34%, the mantissa was 13.68% and the weight was 93.99%, followed by the crustacean (IRI = 1527.99), the incidence was 18.41 %, Mantissa accounted for 80.11%, weight accounted for 2.87%; cephalopods (IRI = 39.42) was 7.58%, mantissa accounted for 2.13%, weight accounted for 3.07%. There were altogether 62 species of food ingested, of which 38 were the largest species, followed by crustaceans and 14 species and 8 cephalopods.
