我国特有品种——中国对虾,历史上最高年产量曾达到4万吨。由于自然变动和人为的大量捕获,产量逐年下降,1987年产量为历史上的最低点——不到5000吨。人工增养殖对虾的迅速发展,需要的亲虾仍然依靠天然捕获,更加剧了天然亲虾数量的减少。为了做到既保护对虾的天然资源,同时又要稳步发展对虾增养殖生产,必须实行对虾的全人工养殖技术,解决亲虾的越冬问题。但在我国,特别是北方地区,由于在人工养殖虾塘中自然交尾率低,造成越冬亲虾生产成本高,给生产带来了严重的障碍。为此,中国水产科学研究院黄海水产研究所杨丛海副研究员
China’s unique species - shrimp, China, the highest annual production reached 40,000 tons. Due to natural changes and man-made mass seizures, the output has been declining year by year. The output in 1987 was the lowest in history - less than 5,000 tons. Artificial aquaculture shrimp rapid development, the need of natural reproduction is still dependent on broodstock, but also exacerbated the reduction in the number of natural broodstock. In order to not only protect the natural resources of shrimp, but also steadily develop shrimp breeding and production, we must implement the full artificial breeding of shrimp technology to solve the problem of overwintering broodstock. However, in our country, especially in the north, due to the low rate of natural mating in artificially cultured shrimp ponds, the production cost of overwintering broodstock is high, which brings serious obstacles to production. To this end, the Chinese Academy of Fishery Sciences Yellow Sea Fisheries Research Institute Yang Conghai associate researcher
