| 摘 要： | 通过养殖实验,比较野生捕捞大眼幼体(G0)和野生亲本人工繁育大眼幼体(G1)在扣蟹养殖阶段的生长、成活率、早熟率和最终产量等指标,结果显示:(1)无论雌体还是雄体,野生群体在扣蟹阶段的平均体质量一直低于野生子一代群体,其中雌体120和150日龄时规格差异显著(P 0. 05);(2)两群体的增重率(weight growth rate,WGR)均呈下降趋势,且野生群体在扣蟹阶段的WGR总体低于人工繁育群体,仅雌体150～180日龄及180～210日龄这两个时间段内高于人工繁育群体;特定增长率(specific growth rate,SGR)变化趋势及差异性与WGR类似;(3)野生群体养成扣蟹的最终平均规格和一龄早熟率均低于人工繁育群体,但平均成活率和最终产量却高于人工繁育群体;(4)野生群体养成的最终扣蟹体质量主要集中于0～4. 00 g(36. 76%),并且显著高于野生G1人工繁育群体(P 0. 05),人工繁育群体体质量主要集中于4. 00～5. 99 g(26. 93%)和6. 00～7. 99 g (25. 43%)这两个范围内,两群体扣蟹在≥12 g体质量范围内的占比均较低,分别为8. 46%和7. 60%。野生亲本繁育子一代的大眼幼体在扣蟹阶段的平均体质量较大,但成活率和平均产量相对较低。通过养殖实验初步比较了两种不同来源的野生大眼幼体在扣蟹阶段的养殖效果,为合理选育和利用野生大眼幼体提供实践依据。
