Problems solved by technology

[0003] The rice field eels cultivated in the prior art are mostly cultivated with soil, which causes the cultured loach to be easily infected by harmful bacteria, and at present, in order to improve the breeding efficiency of most farmers, most of the feeds that are sprinkled are mixed with growth-promoting hormones

Embodiment Construction

[0012] Build a breeding pond with an area of ​​500m2 and a depth of 80cm. The breeding pond is separated into small ponds with 100-mesh stainless steel mesh at equal intervals. Drainage pipes, put in bermudagrass, gray vegetables, and fresh shrimp roe at the same time, add water to the water depth of 75cm in the breeding pond, and put in eel seedlings;

[0013] The water temperature in the culture pond was controlled at 25°C.

[0014] Change the water every 20 days;

[0015] In the first 0-30 days, put 100kg of bermudagrass and 50kg of ash greens every day, put 150kg of bermudagrass and 80kg of ash greens every day for 30-60 days, and put 250kg of bermudagrass and 100kg of ash greens every day for 60-90 days. 90-180 days, put 200kg of bermudagrass and 80kg of gray vegetables every day;

[0016] When throwing ricefield eel seedlings, put 0.8kg / m2 of seedlings with a body length of 10-13cm, put in 1kg / m2 for those with a body length of 15-18m, and put in 10-13cm seedlings wit...

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to an ecological finless eel culture method. The ecological finless eel culture method includes building a culture pond, partitioning the culture pond into small ponds at equal interval, putting finless eels different in length into the ponds for promoting growth balance, putting monochoria vaginalis and chenopodium album with different weights into the ponds by stages, and changing water every 21 days. The method has the advantages that the culture method is simple and easy to implement, freshwater shrimp eggs are spread to enable freshwater shrimp and the finless eggs to grow at the same time, daily nutrition needed by the finless eels can be satisfied by matching with the monochoria vaginalis and chenopodium album due to the fact that the freshwater shrimp reproduce quickly, and the cultured finless eels are high in nutritional value, non-toxic, harmless, pollution-free and beneficial to human health.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological breeding method for rice field eels. Background technique [0002] Swamp eel is a tropical and warm-temperate fish. It is a bottom-dwelling fish with strong adaptability and can survive in rivers, lakes, ditches and rice fields. During the day, it likes to drill holes in the humus silt or live in caves in rock crevices with water on the embankment. It is rarely active during the day and goes out to look for food at night. The gills are underdeveloped, and the skin of the inner wall of the mouth and throat is used as an auxiliary organ for breathing, so it can breathe air directly; it can also survive when the oxygen content in water is very poor. After getting out of the water, as long as the skin is kept moist, it will not die within a few days. Swamp eel is an omnivorous fish that feeds on various small animals. It is greedy in nature. The nutr...
