摘　　要：通过投喂添加β-胡萝卜素质量比分别为50,100 mg/kg的实验饲料,饲养中华绒螯蟹(Eriocheir sinensis)60 d,探讨了对中华绒螯蟹卵巢发育及免疫学指标的影响。结果表明,β-胡萝卜素能够明显增加中华绒螯蟹的质量,提高养殖成活率;极显著提高中华绒螯蟹血细胞吞噬百分率(P<0.01);显著或极显著降低血清超氧化物歧化酶活力(P<0.05或P<0.01);极显著增加卵巢中总类胡萝卜素的含量(P<0.01);显著增加肝胰腺中总类胡萝卜素的含量(P<0.05);较明显增加中华绒螯蟹卵巢指数和卵母细胞直径,但对于肝胰腺指数、卵巢和肝胰腺蛋白质影响较小。The study was conducted to determine the effects of β--carotene on ovary and immunological parameters of Eriocheir sinensis after a 60-day feeding trial. The experimental dietary levels of β-carotene were 50,100 mg/kg. The result showed that β-carotene could increase weight of E. sinensis obviously, raise the survival rate, improve significantly the phagocytic percentage of blood cells of E. sinensis（P〈0.01）,decline significantly superoxide dismutase（SOD）activities in serum（P〈0.05or P〈0.01）, increase significantly total carotenoids in ovary （P〈0.01）, increase significantly total carotenoids in hepatopancrea （P〈0.05） ,increase ovary index and oocyte diameter more obviously. But it had less influence on hepatopancrea index, ovary and hepatopancrea protein.
