草鱼食物链极短,能直接以草料为食,而且生长快,个体大,肉质鲜嫩,经济价值较高,所以向来是水产单位主要的放养对象。但值得注意的是:如果在放养过程中忽视防病,万一发生草鱼肠炎病,就会造成不可估量的损失。关于草鱼肠炎病的治疗,方法很多,效果不一。现将我校水产试验站于1985年用生石灰治愈60亩成鱼塘中草鱼肠炎病的情况,简要介绍如下。 _一、发病情况 1985年5月下旬,60亩成鱼塘中草鱼开始发病,出现零星死亡。6月初,病情发展严重,每天死亡几十尾。同时鲢、鳙鱼死亡更加严重,每天死亡达100斤左右(约150尾)。
Grass carp food chain is very short, can feed directly to the forage, but also grow fast, individual large, fresh meat, high economic value, it has always been the main stocking unit of aquatic objects. However, it is worth noting that if disease prevention is neglected in the process of stocking, incase of grass carp enteritis will result in incalculable losses. About grass carp enteritis disease treatment, a lot of ways, the effect is different. Now my school aquatic pilot station in 1985 with lime to cure 60 acres of fish pond enteritis disease, a brief introduction is as follows. First, the incidence 1985 年 5 月 late in May, 60 acres into fish pond grass carp onset, sporadic deaths. In early June, the disease developed seriously, and dozens of deaths every day. At the same time, the mortality of silver carp and bighead carp were more serious, with about 100 jin of death per day (about 150).
