Abstract:

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.

Key words: early rice, freshwater shrimp, loach, odontobutis obscura, yield, benefit
