摘要
本文报导了斑节对虾子一代,在水泥池中饲养的全过程。越冬存活率为90.6%,饲养期间水温为19.7--31.1℃,盐度为17—26.2℃,越冬水温为20℃左右,用鲜贝肉杂鱼、虾等饲养,斑节对虾在池养条件下,雌虾性腺不能发育成熟,必须施行手术才能诱导性腺发育成熟,从仔虾养到能用于切除单侧眼柄诱导性腺成熟约10个月,施手术到第一尾亲虾成熟产卵为59天。试验表明:在池养条件下,只要饲养管理得当能达到做为亲虾的规格,用切除单侧眼柄的方法,可以培育成为产卵用的亲虾。
This paper reports that the first filial of Penaeus monodon, grown at this college, was cultured in cement ponds at 19. 7—31.1℃ (T) and 17— 26.2‰。(S), then overwintered at 20℃ and the survival rate was 90.6%. The females, cultured in ponds and fed with fresh shell flesh, shrimps and small-fish,could get to be mature only after the induction of unilateral eyestalk ablation. It took about 10 months for postlarvae to grow into adults, and for another 59 days, the first spawner was induced. The above results indicate that the spawner, under pond condition, can be induced by unilateral ablation, providing that suitable management is done and the adults of desirable size are supplied.
