任丘市鱼种场地处白洋淀边,是个繁殖草、鲢鱼种的生产场。由于地理位置和气侯条件的制约,此地虽能为亲鱼提供发情、交配、产卵等生物学条件的适宜时间,但孵化期却只能从6月初开始,适繁期仅有20天左右,时间晚,为期短,影响经济效益。为此,我们进行了利用塑料薄膜大棚温室培育草、鲢亲鱼提早孵化的试验,旨在通过增、保温措施,促进亲鱼性腺早熟,实现一早带百早的目的。一、试验条件与方法 Renqiu City fish market is located Baiyangdian, is a breeding grass, silver carp species production sites. Due to the geographical location and climatic conditions, although it can provide the broodstock with suitable time for biological conditions such as estrus, mating and spawning, the hatching period can only start from the beginning of June and the suitable breeding period is only about 20 days. Late, a short period, affecting economic benefits. To this end, we carried out the use of plastic film greenhouse greenhouse grass, silver carp hatchling early hatch trial, aimed at increasing, insulation measures to promote broodstock gonadal premature, with an early morning with the purpose. First, the test conditions and methods
