由于贵州春季倒春寒较严重，历年来鱼苗的繁殖都是在清明后气温回升基本稳定后进行，这样一来既缩短了鱼苗的生长时间，同时又制约了渔业生产。对此，经过几年的试验总结得出了一定的经验，其技术要点如下：一、产卵池的修造1.材料：砖、石粉砂、水泥。用砖砌墙，水泥砂浆抹池 Due to severe spring in Guizhou in late spring, the fry’s reproduction has been basically stabilized after the temperature rise in Qingming over the years, thus shortening the growth time of fry and restricting fishery production. In this regard, after several years of experiments concluded that some experience gained, the technical points are as follows: First, spawning ponds to build 1 Materials: brick, stone silt, cement. Brick walls, cement mortar pool
