摘　　要：为探讨养殖褐牙鲆(Paralichthys olivaceus)亲鱼后代较野生亲鱼后代质量下降这一问题,本实验分析了野生与人工养殖(包括营养强化处理)褐牙鲆亲鱼肌肉、肝脏及卵中维生素A、维生素C、维生素E含量的差异,并进行了养殖褐牙鲆维生素营养强化的探索实验。结果显示,野生与养殖亲鱼肌肉和肝脏中维生素A含量无显著差异,野生亲鱼卵中维生素A含量显著高于养殖亲鱼(P<0.05);野生亲鱼肝脏和卵中维生素C含量显著高于养殖亲鱼(P<0.05),肌肉中两者无显著差异(P>0.05);维生素E含量在野生和养殖亲鱼各组织内均有显著差异(P<0.05),仅肝脏中养殖亲鱼显著低于野生亲鱼(P<0.05),其余组织均为养殖亲鱼较高。在本实验中,营养强化显著增加了养殖亲鱼肌肉和肝脏维生素A、维生素C及卵和肝脏中维生素E的含量,但对卵中维生素A和C的含量均无显著影响(P>0.05),而肌肉中维生素E含量则显著降低(P<0.05)。上述结果表明,养殖与野生褐牙鲆亲鱼卵中维生素A、C、E含量存在一定的差异,可能与养殖褐牙鲆亲鱼后代质量下降有关,本实验所采用的营养强化方法仅增加了养殖亲鱼卵中维生素E的含量,而对卵中维生素A和维生素C的含量无显著影响,更为有效的强化方式有待进一步研究。A comparison analysis of vitamin A,C and E contents in muscle,liver and eggs of wild,cultured and nutrition fortified Paralichthys olivaceus broodstock was conducted,attempting to explain the decline of larval fish quality in farmed Paralichthys olivaceus.The results showed that no differences were found in vitamin A content of wild and farmed fish,however,egg vitamin A content of wild fish was significantly higher than that of farmed fish（P0.05）.Vitamin C contents in liver and eggs of wild fish were statistically higher than those of farmed fish（P0.05）,while no change were detected in muscle.Vitamin E content in muscle and egg of wild fish were significantly higher than those of farmed fish,with liver vitamin E content following the opposite tendency.Fortification strategies in this study improved vitamin A and C contents in liver and muscle,vitamin E content in eggs of farmed broodstock,while vitamin A and C contents in eggs as well as vitamin E content in muscle changed a little（P0.05）.All the above results reached a conclusion that the discrepancy of vitamin A,C and E contents existed between wild and farmed fish,to some extent,may be correlated with the decline of the larval fish quality in the culture of Paralichthys olivaceus,and this could be diminished by more effective fortification strategies of vitamin A,C and E,which is needed to be further studied.
