海湾扇贝从美国引进以后,因其生长速度快,养殖周期短,经济效益快,深受广大养殖工怍者的欢迎。目前大多采用网笼进行蓄养亲贝,但由于室内海水温度比海区升高的幅度快,温度刺激厉害,亲贝死亡严重,给管理带来很多困难。特别是死亡的亲贝如不能及早清除,在高温下极易腐烂、污染水质。另外在换水、清除死贝时对亲贝刺激极大,易造成亲贝早产卵、排精。针对这些问题,1987和1988年我们分别在文登县海水养殖二场和牟平县养马岛海珍品育苗场采用单层浅水浮动式网箱蓄养海湾亲贝,收到较好的效果。
After the Gulf scallops were introduced from the United States, they are welcomed by the majority of aquaculture workers due to their rapid growth, short breeding cycle and rapid economic benefits. At present, most cage cages are used to support their relatives. However, due to the rapid increase of indoor seawater temperature over the sea level, severe temperature stimulation and serious death of the pro-shell fish, many difficulties have been brought about for management. In particular, if the deceased progeny can not be removed as soon as possible, they are highly perishable and pollute the water at high temperatures. In addition to changing the water, remove dead shellfish on the pro-motivation to stimulate great, easy to cause premature ovulation projectile, ejaculation. In response to these problems, in 1987 and 1988, respectively, we were in Wendeng County, two marine aquaculture and Muping Yangma Island Haizhen Pin breeding farm using a single layer of shallow floating cage cages Bay, received good results.
