笔者通过几年的生产实践，认为网箱养鳝要想取得稳产、高产必须突破“四关”。一、种苗关优质的种苗是实现网箱养殖稳产、高产的关键。从近几年来的渔业生产实践看，黄鳝的人工繁殖虽然取得突破性进展，但仅局限于人工繁殖、孵化两环节，难过育苗关，苗种规模生产仍是一个难题
After several years of production practice, the author thinks that in order to achieve stable production and high yield, the eel must exceed the “four thresholds”. First, seedling off the quality of seedlings is to achieve cage farming stable yield, the key to high yield. From the practice of fishery production in recent years, although the artificial breeding of eel made a breakthrough, it is only limited to the artificial propagation and hatching. It is still a difficult problem to nurture seedling and seedling production.
