鱼种能否安全健壮越冬,直接关系到鱼种养殖户的经济效益和来年成鱼生产的产量。据我们了解,往年有不少的鱼种养殖户由于过早停喂,致使鱼种严重消瘦,到了寒冬季节,往往造成鱼种大量飘塘,损失严重。例如,去年我镇就有一个鱼种养殖户由于过早放松投喂管理,致使鱼种过早消瘦,鱼种头大身子小,肚子落槽,没有活力,抵抗不了冰冻恶劣天气,先后死去近万尾鱼种,损失上千元。为了能使鱼种安全健壮越冬,确保丰产丰收,特提醒有关鱼种养殖户应注意以下几点。一、要抓住晴暖天气,强化越冬投喂管理。鱼类是变温动物,随着气温的逐步下降,鱼儿的摄食量也相应减少。但有不少的人误认为:冬季鱼类进入冬眠不要投喂。其实不然,据我们多年来饲
The safety and robustness of winter fish species are directly related to the economic benefits of fish farmers and the production of adult fish in the coming year. According to our understanding, in previous years, many fish farmers stopped grazing prematurely, resulting in severe wasting of the fish species. In the cold winter season, a large number of floating ponds were often found, causing serious losses. Last year, for example, a fish breeding farmer in my town led to premature ebb and flow of fish, causing the fish to grow prematurely, with its big head, small stomach, no energy and no freezing cold weather, Tail species, the loss of a thousand dollars. In order to make the fish species safe and strong winter, to ensure a good harvest, especially to remind the fish farmers should pay attention to the following points. First, we must seize the warm weather, strengthen the winter feeding management. Fish are warm-blooded animals, with the gradual decline in temperature, the fish’s food intake also decreased. But many people mistakenly believe that: winter fish into hibernation do not fed. In actual fact, according to our years of feeding
