越冬亲虾是进行工厂化育苗生产的基础,没有一定数量和性腺成熟的亲虾,育苗生产就无法进行。因此,提高越冬亲虾成活率,为育苗前期提供数量充足而性腺发育良好的亲虾,是完成育苗指标的前提。可是,近几年来越冬亲虾的死亡率较高,各种虾病常因病因不明而无法控制,从而影响了对虾工厂化育苗生产的发展。有关对虾细菌性病害的研究日本,美国等都有报导。在我国也报导了对虾育
Overwintering broodstock is the basis of industrialized seedling production, without a certain number of gonadal mature broodstock, seedling production can not be carried out. Therefore, to improve the survival rate of overwintering broodstock, nursery stock to provide adequate numbers of gonadal development of good broodstock, is to complete the prerequisite for nursery indicators. However, in recent years, the mortality rate of overwintering broodstock is high, and various shrimp diseases often can not be controlled due to unknown etiological factors, thus affecting the development of industrialized breeding of shrimp. Studies on bacterial diseases in shrimp have been reported in Japan and the United States. Prawn breeding has also been reported in our country
