Using the male and female gametes conserved in the germplasm center after amplified,the Costaria costata seedings were artificially cultivated and cultured in the sea.Began from August 3rd,2015,after 75 dcultivation the seedlings grew to mean length of 0.83 cm and then the seedlings were transferred and fostered in the sea.After 40 dfostering in the sea,the seedlings grew to mean length of 25 cm approximately.Then the seedlings were separated and cultivated in the sea.After that,every 25~30 days the length and width of the Costariacostata were monitored,the seawater temperature was also recorded.The maximum mean length 228.3cm was recorded on April 20 th,2016and the width was 29.3cm,when the seawater temperature was 9.4℃,the mean fresh weight was 528.4g and dry weight was 79.7g,fresh to dry weight ratio was 6.6.It was concluded that Costaria costata could be artificially cultivated in the sea area of north China and the optimum harvest season was late April.
