Abstract: The swordtip squid Uroteuthisedulis, as a shallow marine cephalopod in warm temperature in the sea, is primarily composed of spring, summer and autumn spawning cohorts widely distributed in East China Sea and the southwest of the Sea of Japan, the main spawning grounds in the south of East China Sea and the outer sea. The research achievements of fishery, basic biology, fishing groupd, marine environment and stock assessment of the swordtip squid are reviewed in order to fully understand and utilize the swordtip squid. The swordtip squid is shown to be the target species in East China Sea, but the annual output is decreasing year by year. There was different migration routes in spawning cohorts which were obviously influenced by ocean currents. The spawning, growth and feeding characteristics of the swordtip squid in East China Sea still need to be investigated for a long time. The marine environment has a great influence on the abundance of the swordtip squid stoccks, and stock assessment is more rationally utilized for the resource management. The findings provide scientific basis for the sustainable development and management of the swordtip squid resources in the future.
