一、合理放养。各地为提高鱼种塘利用率,采取多品种混养模式。由于发塘时间的先后,不可能多品种同一时间放养,需考虑利弊得失,扬长避短。如前期投放的鲤鱼夏花,因时间超前及短期内疯长、个体偏大,制约着后期投放的草鱼夏花,所以,凡混养池的鲤鱼夏花必须严格控制并限制投饲,以避免其快速生长,抑制它对后放的草鱼夏花的干扰及危 First, a reasonable stocking. In order to improve the utilization of fish species ponds, adopt multi-species polyculture mode. Due to the sequence of pond time, it is impossible for many breeds to be stocked at the same time, and the pros and cons of the breed should be considered in consideration of strengths and weaknesses. Carp summer flowers, such as pre-delivery, due to time ahead and short-term soaring, the individual is too large, restricting the latter part of put grass carp summer flowers, so where polyculture pond carp summer flowers must be strictly controlled and limited feeding to avoid its Rapid growth, inhibition of its release on the grass carp summer interference and danger
