【Abstract】 The distribution area of Acetes chinensis is influenced by the seasonal change of temperature and salimity of sea water. In spring, the shrimp groups migrate from off shore waters to inshore area. In summer and autumn, they part to spawn at shallow waters. At the end of autumn, they begin to leave inshore areas for deep sea.There are two generations of Acetes chinensis, the Ist is born in May to July, and the 2nd in July to September.The yield of shrimps is related with the amounts of larva of the year. Then, the protection of young shrimps and controling the fishing intensity of spawning groups are great importance.更多还原
