摘　　要：以蟹草共生系统为研究对象,研究了几种不同沉水植物搭配模式对河蟹养殖池水质改善效果及对河蟹性腺、肌肉,肝脏免疫活性的影响。结果表明:蟹草共生系统较常规养殖有显著改善养殖水体的效果,其中种植多品种沉水植物搭配对蟹池水体总氮、总磷、氨氮、高锰酸钾盐指数的去除效果明显好于种植单一品种沉水植物。SOD、CAT、T-AOC、AKP、ACP、UL及Na+/K+-ATPase在3个种草蟹池河蟹的性腺中活性最高,Ca2+/Mg2+-ATPase在伊乐藻+黄丝草及复合草组河蟹的肌肉中活性最高,在伊乐藻组河蟹的性腺中活性最高,各河蟹免疫因子活性在不同养殖河蟹不同组织存在一定的异同。Three kinds of ecosystems which compounded with different submerged plants and crab （Eriocheir sinensis） co-cultured were made,and the effects of the three ecosystems on the water quality index and immune parameters in different tissues （gonad,muscle and liver） were detected in the culture period. The results showed： ecosystems compounded with kinds of submerged plants and crab can significantly improve the water quality, while,the one compounded with various submerged plants have a significantly better results on the water improvement than the one with mono-plant. The activities of immune parameters such as SOD,CAT,T-AOC, AKP,ACP,UL and Na＋/K＋-ATPase are highest in gonads of crabs which were cultured in the three ecosystems. The activities of Ca2＋/Mg2＋-ATPase were highest in muscles of crabs which were cultured in two ecosystems of submerged plant elodea and potamogeton maackianus,and multiple grass,but was highest in gonads of crabs which cultured in the ecosystems of submerged plant elodea. There was difference among the immune parameters activities in different tissues and crabs in the different ecosystems.
