摘要
把生态学理念应用到欧洲鳗鲡养殖管理中,通过调控养殖水体生态环境因子,建立多样性水体生物结构,最大程度提高养殖水体自净和生态防病抗病能力,实现少换水、少用药的养殖效果。试验共投白仔苗100万尾,经过280d的养殖,共收获鳗鱼54890kg,平均59g/尾,成活率97.8%。与往年相比,养殖周期缩短,换水率和病害发生率明显降低,养殖成本随之下降。
The ecology theory was applied to the management of the culture of Anguilla anguilla.Establishing a diversity of biological water structures through regulating water qualities can improve the self-purification ability of water and disease prevention,And the consumption of water and drugs was greatly decreased in the process of culture.There were 1 million glass eels in total and after 280 days＇ culturing,we harvested 54890 kilograms of Anguilla anguilla with an average weight of 59 grams,and the survival rate was 97.8%.Compared with the previous culturing,it was remarkably evident that the cultural time was shortened and the feeding cost also declined with a great drop of water exchange rate and disease incidences.
