The reproductive biology, and age and growth of the swordtip squid (Photololigo edulis) in the East China Sea were examined based on the growth ring of statoliths from 1797 specimens during the period of November 2002 to November 2004. The maximum age observed was 261 days in female and 253 days in male, an evidence showing that swordtip squid has a longevity of about 9 months in both sexes. Growth in mantle length (ML) and body weight (BW) in both sexes was best described by the exponential model. There was significantly difference in somatic or statolith growth between the sexes. …
