The invention discloses a
micropterus salmoides fingerling out-of-season cultivation method which comprises the following steps: S1, pond preparation: the area of a pond is 5-8 mu and after pond wateris drained, the thickness of
sludge in the pond is kept at 8-12 cm, about 5-15 cm of accumulated water is left in the pond, quick
lime is used for cleaning the pond at 100-150 Kg / mu, and after 7-14 days, water is injected into the pond, the water injection depth is 0.8-1.8 m, and a net cage is arranged in the pond. The
micropterus salmoides SHUIHUA in autumn are cultured through the net cages, and the
survival rate of the SHUIHUA can be effectively increased; secondly, the bait
utilization rate can be increased through cultivation in a
cement pond, and the fry physique is effectively enhanced; finally, proper growth temperature is provided for the fish fries in winter through a
greenhouse and a boiler
temperature control technology, and therefore it is guaranteed that the fish fries are kept in a rapid growth state all the time to be cultured into large-size fish fries. The
micropterus salmoides large-size fingerling out-of-season breeding technology provides
technical support for production of micropterus salmoides large-size fingerlings, and meanwhile has great significance in promoting transformation and upgrading of micropterus salmoides breeding
modes in northern areas.
