【摘要】 在水温27±2℃,盐度29±2;pH8.0~8.5,光强1 000 1x的条件下,对来自我国台湾的1 300对规格为35~45 g/尾的凡纳滨对虾亲虾进行为期73 d的驯养、促熟、产卵及无节幼体培育试验.结果表明,整个试验过程中,亲虾平均存活率为99.458%,波动区间[99.583%,99.333%],日产卵亲虾比例平均为3.506%,波动区间[3.89%,3.123%],雌虾单尾次日产无节幼体数量平均为18.928%,波动区间[19.691%,18.164%].无节幼体的日产量随繁殖驯养的延长,呈渐渐上升态势,从240万尾(第21天)至2 135万尾(第54天)平均为1 323万尾.此外,试验发现近成熟的雌虾也能接受交配行为.

【Abstract】 This experiment was conducted to study the domestication,maturation,spawning of 1 300 pairs of pond-reared Litopenaeus vannamei broodstock from Taiwan with body weight of 35~45 g/ind.and nauplii rearing for 73d under water temperature of 27±2℃,salinity of 29±2,pH 7.8~8.5 and light of 1 000 lx.The results showed that the daily average survival rate of the broodstock was 35.06%,fluctuation interval was [99.583%,99.333%];the daily nauplii average production of every spawned broodstock was 18.93×104 ind.,fluctuation interval was [19.69×104 ind.,18.16×104 ind.];the daily naupii average production was 1 323×104 ind.,increasing from 246×104ind(21th d)-2 135×104(54th d) during the experiment.In addition,it was reported that the near matured female can accept the mating of the male and mated female had not been observed died during the spawning.
