二、罗非鱼的人工繁殖技术(上) 罗非鱼的繁殖,不需要进行人工催情产卵和流水刺激,只要水温稳定在18℃以上,将成熟的雌、雄亲鱼放入同一繁殖池中,待水温上升到22℃时,就能自然杂交繁殖鱼苗。在水温25℃～30℃的情况下,每隔30～50天即可繁殖一次。下面以奥尼鱼的制种过程为主介绍罗非鱼的繁殖制种技术。 Second, the tilapia artificial breeding techniques (on) Tilapia breeding, do not need artificial aphrodisiac spawning and water stimulation, as long as the water temperature stabilized at above 18 ℃, the mature female and male broodstock into the same breeding pool , Until the water temperature rose to 22 ℃, you can naturally breed fry. In the case of water temperature 25 ℃ ~ 30 ℃, every 30 to 50 days to breed once. The following process to seed the production of Omni Tilapia breeding seed production technology.
