四、成鱼养殖多瑙河六须鲶的生活温度为0—36℃,12—34℃为最适温度,摄食旺盛并集群,8℃以下则摄食较少,活动能力下降,失去集群现象:4℃以下完全停止摄食,伏底不动,当水温超过36.5℃时多瑙河六须鲶群体开始分散,上下狂窜不安,37.5℃时开始死亡,38℃则无一幸存。多瑙河六须鲶不但适温广,其对溶氧的要求也很低,与鲤相近,所以多瑙河六须鲶的养殖是比较容易的,与我国四大家鱼的养殖方式相似,它除了摄食人工配合饲料外,还喜欢吃大型的浮游动物,昆虫及其幼体,水蚯蚓、蝎虾、蝌蚪等,甚至小青蛙也是它喜
Fourth, the adult fish breeding Danube bearded catfish living temperature of 0-36 ℃, 12-34 ℃ for the optimum temperature, feeding strong and clusters, less than 8 ℃ less food intake, decreased activity, loss of cluster phenomenon: 4 ℃ The following completely stop feeding, the bottom of the boat does not move, when the water temperature exceeds 36.5 ℃ when the population began to disperse the Danube Six groups, catastrophic up and down, began to die at 37.5 ℃, 38 ℃, no one survived. The Danube 6 catfish not only suitable for wide temperature, its requirements for dissolved oxygen is also very low, and common carp, so the Danube six species of catfish breeding is relatively easy, and China’s four major domestic fish culture in a similar way, in addition to ingest artificial cooperation Feed, but also like to eat large zooplankton, insects and their larvae, water, earthworms, scorpion shrimp, tadpoles, and even small frogs are like it
