秋天,虽然气温逐渐转凉,水温也随之下降,但这阶段,特别在前期仍然是鱼类生长和积累营养的重要时期,所以秋季鱼塘管理,对提高塘鱼规格和增加鱼产量都具有重要作用。 早秋的水温仍适于鱼类的生长。此时各种饲草的数量多,质量好,水质也不很浓,要狠抓草食性鱼类的投食,促使草鱼长肉,争取大部分草鱼在9月底以前,达到上市规格。所以在天气正常,无浮头危险的日子要大量投饲。一般8～9月的投饲量占全年总投饲量的41％。但9月上旬白露前后小草鱼容易发病,要适当控制投饲量,原则上以下午吃完为度。9月下旬以后,鱼病高发季节已过,又可大量投喂,日夜吃食,这对促进鱼体增重和
In autumn, although the temperature gradually turns cold and the water temperature decreases, this period, especially in the early period, is still an important period for fish growth and nutrient accumulation. Therefore, the management of autumn fish ponds has the following implications for improving the specifications of the pond fish and increasing the fish production Important role. Early autumn water temperature is still suitable for fish growth. At this point a large number of forage, good quality, water quality is not very strong, we should pay close attention to herbivorous fish feeding, prompting grass carp long meat, for the majority of grass carp before the end of September, to the market size. So in the normal weather, no risk of floating head to a large number of feeding. Generally 8 to 9 months of the total feeding volume of 41%. However, in early September before and after the white exposed grass carp easy to disease, should be appropriate to control the amount of feeding, in principle, to eat degrees for the afternoon. After late September, the season of high incidence of fish disease has passed, but also a large number of feeding, day and night eating, which is to promote the body weight gain and
