太平洋牡蛎(Crassostrea gigas)亲贝进行升温促熟,有利于早出苗、出大苗、海区吊挂养殖、滩播养殖、虾池混养等,当年即可达到商品规格进行收获,缩短了养殖周期。同时升温促熟进行太平洋牡蛎控温育苗,可进行多茬育苗,提高了育苗池的利用率。升温促熟与产卵时间的确定是太平洋牡蛎人工控温育苗的关键之一。具体方法: 1.亲贝的入池时间 亲贝入池在3月份为主,最晚不要迟于4月初。北方沿海自然水温在5～10℃范围内,此时将壳长8.0cm以上的亲贝经挑选、洗刷干净后,按每层5～7
Pacific Oyster (Crassostrea gigas) pro-shell temperature to promote ripening, is conducive to early emergence, a big seedlings, the sea hanging culture, beach sowing, shrimp pond polyculture, then you can reach the product specifications for harvest, shorten the breeding cycle. At the same time, the temperature and maturity of the Pacific oyster temperature control nursery, nurturing more stubble, raising the utilization rate of nursery ponds. It is one of the keys to artificial temperature-controlled nursery of Pacific oyster to determine the timing of warming and spawning. Specific methods: 1. Pro shell into the pool time pro into the pool in March based, the latest not later than early April. The northern coastal natural water temperature in the range of 5 ~ 10 ℃, this time the shell length of 8.0cm above the pro-selected, washed clean, according to each layer 5-7
