江浙一带露天养鳗池,均有长达4个月(11月～翌年3月)的越冬期。如何根据鳗鱼本身的生理特点,加强越冬管理,最大限度避免越冬损失,这对发展下一年的鳗鱼生产十分重要。我场根据以往几年正反两方面的教训,采用以下技术措施: 一、提前越冬并塘我场一般在十月上旬开始进行鳗鱼越冬并塘,将所有鳗鱼按规格大小作不同处理: 10克以下的新鳗种,体质较弱,越冬成活率较低,因此并塘时将全部迁入塑料大棚内加温继续饲养;100—150克接近出口规格
Open-pit eel pool in Jiangsu and Zhejiang, have up to 4 months (November ~ next March) winter. According to the physiological characteristics of the eel itself, how to strengthen the winter management and minimize the winter damage is very important for the development of eel production in the next year. According to the positive and negative lessons learned in previous years, we adopted the following technical measures: I. Early winter and pond Generally, the eel began to be overwintered and ponds were formed in early October. All the eels were treated according to their specifications and sizes: 10 g The following new eel species, physical fitness is weak, lower survival rate of overwintering, and pond will be all moved into the plastic greenhouse to continue heating; 100-150 grams close to the export specifications
