本文以实验生态方法对白虾Exopalaemon carinicauda的繁殖习性、胚后幼体发育及人工育苗进行了初步研究。所得结果:(1)我国北方白虾1年内产生两个世代。越冬后的亲虾在春、夏季产生第1世代,第1世代亲虾夏、秋季产生第2世代。(2)白虾胚后幼体发育到仔虾经过6次蜕皮,即6个幼体期。(3)在打气条件下,以卤虫幼体为饵料进行人工育苗,从幼体培育到仔虾成活率可达80%左右。
In this paper, the ecological habits of white shrimp Exopalaemon carinicauda breeding habits, post-embryonic development and artificial seedling breeding conducted a preliminary study. The results obtained: (1) North China white shrimp produce two generations within one year. The overwintering broodstock produced the first generation in spring and summer, the first generation broodstock summer, and the second generation in autumn. (2) After the larvae of white shrimp embryos developed to 6 larvae after molting, that is, 6 larvae. (3) Artificial breeding of Artemia salina larvae as bait under inflated conditions, the survival rate from juvenile to larvae reached about 80%.
