The invention relates to the technical field of aquaculture, in particular to a controllable rice-eel co-farming method.
Background
The finless eel (Monopterus albus) has high nutritional and medicinal values and wide market prospect. The modes of cage culture, pond eel culture, greenhouse culture and the like are developed rapidly all over the country, and a good culture effect is obtained. However, the situation that the breeding period is long, the breeding survival rate is low, the quality of finished eel is poor and the breeding risk is high is not got rid of yet.
The rice and eel combined cropping mode belongs to an ecological breeding mode, can improve the breeding survival rate of rice eels, reduce the breeding cost and the breeding risk, has good quality of the rice eels eating live baits, can improve the quality of rice, ensures the grain safety of China and improves the economic benefit of grain fields. However, the rice and eel cropping mode in China is slow to develop so far, the rice field eel cropping area is very small, and the rice field eel cropping mode only has sporadic breeding in Zhejiang, Hubei, Jiangsu, Shanghai, Anhui and other places, including several modes of rice and eel cropping, rice and eel and loach cropping and the like, most of the modes still stay at the level of production experience, and mainly because the traditional rice and eel cropping mode has the problems of long production period (2-3 years from seedlings to commercial eels with the weight of more than 100 g/tail), low yield (less than 25 kg/mu), low benefit (2000 yuan/mu) and the like.
Therefore, there is a need to develop a new rice and eel farming method.
