Problems solved by technology

However, in recent years, due to the extensive use of pesticides in paddy fields, the seedlings and natural food resources of rice field eels have been damaged; at the same time, due to the continuous increase in fishing intensity, the number of parent eels has decreased, resulting in a sharp decline in natural resources.

Embodiment Construction

[0020] The embodiment is described in detail below:

[0021] A kind of eel-rice symbiotic culture method, it is characterized in that, the steps are as follows:

[0022] 1): Selection of paddy fields: the suitable area is 600-2000 square meters, the pH value is between 7-8, and the soil is preferably clay, which has good water retention;

[0023] 2): Setting of inlet and outlet of paddy fields: set fixed fish nets at inlet and outlet;

[0024] 3): Excavation of eel ditches and eel pits in rice fields: excavate a 0.8-meter-wide and 0.5-meter-deep eel ditch at a distance of 2 meters from the shore around the rice field, and excavate a 0.8-meter-wide and 0.5-meter-deep eel ditch in the middle of the rice field. In the well-shaped eel ditch, a eel pit with a length and width of 3 meters and a depth of 0.6 meters is excavated at each of the four corners of the rice field. The area is controlled at about 10% of the paddy field area, and a certain amount of water peanuts are placed...

Abstract

The invention belongs to the technical field of aquiculture, and particularly relates to an eel-rice symbiotic cultivation method. The eel-rice symbiotic cultivation method disclosed by the invention comprises the following steps: 1. selecting a rice field; 2. arranging fixed pound nets in a water inlet and a water outlet; 3. digging eel ditches and eel pits in the rice field; 4. defining stocking time: stocking eels after paddy rice seedlings revive; 5. three days later after the eels are stocked, starting to feed the eels; 6. fishing and selling, wherein un-fished finless eels overwinters in the rice field naturally. The method has the advantage that finless eels are the natural enemy of rice insects, and can eat a large proportion of insects to reduce the quantity of parasitic insects in paddy rice, so that no disinfestant is used during the whole growing process of the paddy rice. Therefore, rice produced according to the method is high in quality, nutritional and tasty; the yields of eels and rice produced according to the method are high.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a symbiotic breeding method for eels and rice. Background technique [0002] Swamp eel is a subtropical fish, commonly known as eel, which has a wide geographical distribution in my country, especially Anhui, Jiangxi, Jiangsu, Zhejiang and Shanghai in the middle and lower reaches of the Yangtze River and the Pearl River Basin. It is one of the main freshwater economic fish in my country'. The rice field eel meat is tender and delicious, and has rich nutritional value. Eel is rich in DHA and lecithin, which are the main components of the cell membranes of various organs and tissues of the human body, and are indispensable nutrients for brain cells. The special substance "salmonin" contained in eel can lower blood sugar and regulate blood sugar, and has a good therapeutic effect on diabetes. In addition, it contains very little fat, so it is an ideal food for diabe...
