Keyword:  革胡子鲶提高成活率鱼苗下塘如何提高浮游动物搭养革胡子鲶鱼养殖方式天然饵料池塘养殖;
Abstract: 池塘搭养革胡子鲶,这种养殖方式已被我省广大养鱼户及生产单位所接受。该养殖方式具有革胡子鲶生长快、成本低、效益高等特点,在不必单独投饵的情况下,靠天然饵料和争食争氧的野杂鱼便可获得产量,是池塘增产增收的好措施。但从我省各地养殖情况来后,成活率普遍很低。如果能把成活率提高上去,该养殖方式大有前途。如何提高成活率呢,本人就此谈一些粗浅的观点。l成活事低的原因1.1鱼苗入塘时数量不足我省的胡子鲶鱼苗大多数是从外省调运来的,由于鱼苗装袋时数量不足,以致于按此数放入池塘中的数量就不足,直接影响了成活率。1.2革胡子鲶鱼苗下塘时规格小据统计,池塘养殖放养4.5cm鱼苗,成活率约为50%~70%,放养7cm的
