“青虾-早稻-泥鳅-沙塘鳢”共生高产高效生态种养模式，通过种植早稻，由早稻“吸肥去污”，净化池塘水质，从而提高水产品质量；青虾可耕地除草，取食稻田害虫，减少水稻虫害；泥鳅会钻地松土，在稻田中起到除草造肥、除虫、增加水体溶解氧的作用；沙塘鳢可食小虾，从而提高虾的商品性。本文从稻田选择、田间设施建设、早稻种植、青虾（泥鳅、沙塘鳢）养殖等4个方面介绍了该模式的种养技术，分析了该模式的经济效益、社会效益和生态效益。

The ecological commensal cultivation pattern of “Freshwater Shrimp-Early Rice-Loach-Odontobutis obscura” system could improve the quality of aquatic products, because early rice could absorb excrement as fertilizer to pure the quality of water; freshwater shrimp could plough, weeding, which could decrease the damage of pests in rice field; loach could loose soil of rice field, weeding, control insects, produce fertilizer, which could increase dissolved oxygen in water; odontobutis obscura could eat part of small-size shrimps, which could improve the yield and specification of commodity shrimps. This paper introduced the cultivation techniques about choice of rice field, construction of field facilities, early rice cultivation, breeding of shrimps, loach and odontobutis obscura, analyzed the economic benefit, social benefit and ecological benefit of this pattern.
