海湾扇贝在工厂化人工育苗中,是通过亲贝蓄养来促使亲贝成熟并进行产卵的,但由于其孵化率一直不很高,故各单位普遍采用培养大量种贝做保证,以采到足够的受精卵,达到一定数量的幼虫,进行扇贝育苗生产。这样耗费大量的人力、物力、财力。因此提高海湾扇贝受精卵的孵化率在海湾扇贝育苗工作中极为重要。为此,我们根据几年的生产经验,总结出影响海湾扇贝受精卵孵化率的几项措施。1.海湾扇贝卵是否成熟是决定其孵化率的主要因素:
Bay scallops in artificial plantation artificial breeding, is through the pro-shell cultivation to promote the progeny mature and spawning, but because of its hatching rate has not been very high, so the unit widely used to cultivate a large number of shellfish to ensure that in order to adopt Enough to fertilized eggs, reaching a certain number of larvae, scallop nursery production. This consumes a lot of manpower, material and financial resources. Therefore, it is very important to improve the hatching rate of the Gulf scallop fertilized eggs in the bay scallop nursery. To this end, we based on several years of production experience, summed up the impact of Gulf scallop fertilized egg hatching rate of several measures. 1. Bay scallop eggs is the key to determine the maturity of the hatching rate of the main factors:
