近几年因鱼市低迷,不少池塘养殖户反映效益不理想,但仍有不少养殖户取得了丰收。而其中不少人的养殖经验和管理水平都和他们差不多,为何有此落差呢?俗话说:“三分种、七分养”,好的开头便是成功的一半,为此笔者结合鱼种放养过程中经常容易忽略的几个问题提三条建议,供大家参考。 1、在同一地方购买鱼种 如果池塘放多地方的鱼种,因它们以前生存环境不一样,它们身上所携带的寄生虫、病菌的品种和数量也不同。并入同—个池塘后交叉感染的机会增大,生病的可能性大大增加,病情也更趋于复杂化,增加了药品的支出。 2、要尽量买优良纯正的品种优良品种的鱼饲料转化率高、生长迅速、病害少。实验
In recent years due to the downturn in the fish market, many pond farmers reflect the benefits are not satisfactory, but many farmers have achieved bumper harvest. And many of them have the same level of experience in farming and management as the others. Why is there such a gap? As the saying goes: “One-third species and seven-species well-being” begin well with half the success. Stocking process is often overlooked several issues to mention three suggestions for your reference. 1, to buy fish species in the same place If ponds place more fish species, because of their previous living environment is not the same, they carry the parasites, bacteria, varieties and quantities are also different. The chances of cross-infection increase after incorporation into the same pond, the likelihood of illness is greatly increased, the condition is more complicated and the expenditure on medicines is increased. 2, try to buy fine pure varieties of fine varieties of fish feed conversion rate, rapid growth, less disease. experiment
