目前我省饲养革胡子鲶鱼,大部分鱼苗需从南方购进。为提高成活率,在运输和下塘时应注意以下六点: 1.供氧:运输方式分两种,即封闭式和开放式运输。短距离适合开放式运输,一般用干净光滑的大塑料桶盛水装苗。长途运输则采用塑料袋充氧硬纸箱包装密闭式运输。密闭式运输的鱼苗,体内往往含有较多的二氧化碳,使鱼苗处于麻醉甚至昏迷状态。如将这种状态的鱼苗直接下塘,成活率极低。
At present, our province keeps leather catfish, most of which need to be purchased from the south. In order to improve the survival rate, the following six points should be paid attention to when transporting and transporting ponds: 1. Oxygen supply: There are two modes of transport, enclosed and open transport. Short distance suitable for open transport, generally with a clean, smooth plastic bucket filled with water. Long-distance transport is used plastic bags oxygenated carton packaging closed transport. Sealed fish fry, the body often contain more carbon dioxide, the fry in anesthesia and even coma. If the state of the fry directly under the pond, the survival rate is very low.
