海湾扇贝的苗种生产常采用提早加温育苗的办法,这样需要近一个月的亲贝蓄养,以使其性腺成熟,保证采到足够的优质卵。因此海湾扇贝亲贝蓄养是十分重要的。目前大多采用网笼进行蓄养亲贝,但因室内海水温度比海区的升温幅度快,温度对其刺激厉害,亲贝死亡率高。同时,也给管理带来了很多困难,而且劳动强度也大,特别是死亡亲贝因挑选麻烦,不能及时清
Bay scallops seed production often used to raise the temperature early breeding approach, which requires nearly a month of pro-cage storage, in order to make the gonads mature, to ensure adequate quality eggs. Therefore, the Gulf scallops pro-shell conservation is very important.

At the same time, it also brings a lot of difficulties to the management, and the labor intensity is also great, especially the death of the parents because of the selection trouble, can not be promptly cleared
