【中文摘要】 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.
