乐亭县自1986年开始利用越冬虾苗养虾,当年取得明显成效。随后几年,亲虾越冬规模不断扩大,放养面积逐年增加,越冬虾苗以其成活率高、产量高、效益大而普遍被虾农所认识。但近几年来,由于种种原因,越冬苗的放养面积有所减少。在这种情况下,为了推动亲虾越冬工作的顺利开展,我们认真总结了过去几年正反两方面的经验教训,积极探索用越冬虾苗养虾的规律。不断改进养虾方法,研究出一套放养越冬苗获得高产的新技术 Laoting County since 1986, the use of shrimp and shrimp shrimp, the year achieved remarkable results. In the following few years, the scale of overwintering broodstock continued to expand, and stocking area increased year by year. Overwintering shrimp seedlings were generally recognized by shrimp farmers for their high survival rate, high yield and large benefit. But in recent years, due to various reasons, the stocking area of ​​overwintering seedlings decreased. Under such circumstances, in order to promote the smooth progress of the work of overwintering broodstock, we have earnestly summed up the positive and negative experiences and lessons from the past few years and actively explored the law of shrimp cultivation in the overwintering shrimp culture. Constantly improve the shrimp farming methods, developed a set of stocking winter seedlings to obtain high-yielding new technology
