Problems solved by technology

In summer, the surface of the pool is bare and unobstructed, and the temperature of the pool rises rapidly. The eels in the pool often die due to the high water temperature in the pool, causing huge losses to farmers.
In addition, because the ponds are all bottomless mud ponds, the eels slipped away from time to time, which greatly reduced the income of the farming households.

Embodiment Construction

[0013] As shown in the attached figure, first drain all the water in the breeding pond, set the lotus root pond 1 at 1.5M wide, and the eel pond 5 at 1.5M wide, and dig the floating mud in the eel pond until it bottoms out. First, build red bricks around the eel pond and the bottom, and smooth it with cement mortar to prevent the lotus root from growing into the eel pond, and the eel is easy to slip away when it grows up. Put the floating mud into the repaired eel pond for 20-30cm. Repair the lotus root pond 1 and the eel pond 5 in the breeding pond one by one in this way, put into 1 meter deep water 3, put the net cage 4 into the eel pond 5 and arrange it, and the net cage is higher than the water surface 30-50cm , put rice field eel seedlings into the net cage, put 6kg per square meter, put engineering fly live maggots into the eel pond twice a day, and measure the water temperature regularly. After 7 months of repeated feeding in this way, the rice field eels can be release...

Abstract

The present invention relates to an ecological cage culture method of finless eel, including lotus rhizome, finless eel, interval culture and using engineering fly-maggot as feed. Said invention provides a good culture environment for grwoth of finless eel, use high-quality high protein engineering fly-maggot as feed so as to can greatly raise finless eel culture density, can shorten feeding period, and its yield can be raised by 50-100%.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to a method for cultivating rice field eels in ecological net cages. Background technique [0002] Nowadays, rice field eels are generally fed in earthen ponds and cement ponds, and the food is mostly small fish and earthworms. The disadvantage is that the feeding cycle is long, and it takes about 14 months to be released from the ponds. The stocking density of rice field eels is low, and only 3kg per square meter can be stocked. . Even if it goes out of the pool and goes on the market, the weight of a single eel is light and the total output is small. In summer, the surface of the pool is bare and unobstructed, and the water temperature in the pool rises rapidly. The eels in the pool often die due to the high water temperature in the pool, causing huge losses to farmers. In addition, because there are bottomless mud ponds in the ponds, rice fiel...
