夏花草鱼一般是与鲢、鳙鱼搭配混养的,但它们的食性,在鱼苗初下塘时基本上是相同的,都能摄食一些浮游生物以及投喂的精饲料;到夏花阶段,食性才有明显的差异,鲢、鳙鱼以食浮游生物为主,草鱼由食浮游动物转向取食大型浮游动物及底栖生物,4 cm以上才吃嫩草,逐步转为草食性,且喜欢水质清晰。但由于混养在鲢、鳙鱼和池中。水质都较肥沃,对草鱼的生长不利,尤其是夏花阶段。死亡率最高。因为鱼体幼嫩,食性的转变与外界环境的变化不相适应,同时在这一阶段,正值草鱼的白头白嘴病、车轮虫病流行季节,如果不加强饲养管理,采取一些必要的措施。就会导致夏花草鱼的大批死亡。因
Summer grass carp is generally mixed with silver carp and bighead carp, but their feeding habits are basically the same in the early pond when they are young, they can feed on some plankton and fed the fine feed; to the summer flower stage, There was a significant difference in feeding habits between silver carp and bighead carp. Most of the carp and bighead carp fed on plankton. Grass carp switched from feeding zooplankton to large zooplanktons and benthic organisms, eating grass and grass more than 4 cm, gradually converting to herbivore, and liked Water quality is clear. However, due to polyculture in silver carp, bighead carp and pool. Water quality is more fertile, grass carp growth is unfavorable, especially the summer flower stage. Highest mortality rate. Because the tender and feeding habits of fish do not adapt to changes in the external environment, at the same time, at this stage, it is worthwhile to take some necessary measures in the season of white-billed white mouth disease and rotifer epidemic of grass carp. . It will lead to a large number of summer grass fish deaths. because
