A method of controllable rice eel co-cultivation

Abstract

The invention discloses a controllable rice eel co-cultivation method, comprising the following steps: constructing a double-span multi-span plastic shed, building a 3-5-layer three-dimensional culture pond in the shed, cultivating rice field eel with circulating water, and then cultivating rice field eels with large specifications. The rice field eels were put into the paddy field for breeding. The present invention utilizes three-dimensional circulating water in plastic greenhouses to breed ricefield eels at high density, grows ricefield eel seedlings into large-scale eels in the greenhouse for 4-6 months, grazes large-size eels in rice fields every June-July, and captures ricefield eels in October-November. Thereby shortening the production cycle and greatly improving economic benefits.

Description

Technical field [0001] The present invention relates to the field of aquaculture technology, in particular to a controllable method of rice eel co-cultivation. Background [0002] Monopterus albus has high nutritional and medicinal value and broad market prospects. Cage culture, pond eel culture, greenhouse culture and other models have developed rapidly throughout the country and achieved good breeding results. However, the cultivation of yellow eel has not yet got rid of the situation of long breeding cycle, low survival rate of aquaculture, poor quality of finished eel and high risk of breeding. [0003] The rice eel co-cultivation model belongs to the ecological breeding model, which can improve the survival rate of yellow eel farming, reduce the cost of breeding and breeding risks, eat live bait yellow eel quality is good, and can improve the quality of rice, ensure China's food security and improve the economic benefits of grain fields. However, China's rice eel co-cultivat...

Problems solved by technology

However, the rice-eel co-cultivation model in my country has developed slowly so far, and there are very few places to raise eels in rice fields. Most of the rice eel co-cropping and other modes still remain at the level of production experience, mainly because the traditional rice eel co-cropping has a long production cycle (from seedlings to commercial eels with a weight of more than 100 g / tail requires 2- 3 years), low yield (less than 25 kg / mu) and low benefit (2000 yuan / mu)
