在当前传统养殖鱼类品种受市场经济条件制约较大的情况下,发展名优新水产品养殖尤为重要。在此形势下,洪湖周边地区的黄鳝养殖业如雨后春笋般脱颖而出,由分散的作坊式庭院经济养殖,迅猛发展为大规模、连片集约化养殖。但由于黄鳝的人工繁殖技术还不十分成熟,所需菌种仍依靠天然捕捞解决,因而造成苗种价格的飞涨,养殖成本不断加大,养殖风险逐年提高。而且由于苗种质量和技术等方面的原因,苗种投放后7—10天即发生死亡现象,有的养殖户损失达80%以
Under the condition that the traditional cultured fish species are greatly restricted by the market economy conditions, it is especially important to develop famous and new aquatic products breeding. In this situation, the eel aquaculture around the area around Honghu has mushroomed to emerge from the scattered cultivation of the courtyard of the economy farming, the rapid development of large-scale, contiguous intensive farming. However, due to the eel artificial breeding technology is not yet very mature, the required species still rely on natural fishing solution, resulting in soaring prices of seedlings, breeding costs continue to increase, raise the risk of breeding year by year. And because of seed quality and technology and other reasons, 7-10 days after the death of seedlings that the phenomenon of death, and some farmers lost up to 80%
