Method and device for culturing rice field eel

Abstract

The invention relates to a method for cultivating swamp eels and a device thereof and pertains to the technical field of agricultural cultivation, which is used for solving the problem of industrial high-density cultivation of the swamp eels under the unnatural conditions. The technical proposal thereof is that a three-dimensional multilayer small-area controllable water level combined-typed cultivating pool is arranged at the heliophobe indoor; according to the living habits and requirements of the best growing environmental conditions of the swamp eels, water source, the conditions of water quality, breeding density and bait proportion are configured for cultivating the swamp eels. Meanwhile, the three-dimensional combined-typed cultivating pool, a filtration pool, a deposition pool, an oxygenation pool, a dosing pump, a disinfector, a thermostat, and the like, form a closed water cycle system. And the problems of water supply, filtration, deposition, disinfection, constant temperature, constant flow, oxygenation, pollution discharge, and the like, under the condition of high density cultivation are solved in the cycle. By applying the method and the device of the invention, the swamp eels can be cultivated all the time without the influences of season and climate, and the large-scaled industrial cultivation of the swamp eels which are excellent special aquatic products can be realized.

Description

technical field [0001] The invention relates to a method and a device for cultivating rice field eels, belonging to the technical field of agricultural breeding. Background technique [0002] At present, the production methods of ricefield eels are not only wild, but also artificial breeding mainly includes hanging net cages, earthen ponds and cement ponds on the water surface for seasonal breeding. All methods also have many problems such as large water occupation, high bait coefficient, low output per unit area, short breeding cycle limited by seasons, heavy natural weight loss in winter, polluted water quality and high incidence of disease. CN1418540 discloses a method for cultivating field eels in ecological net cages outdoors. Field eels are cultured in net cages in a culture pond. This method cannot guarantee the temperature of the water in the pond, especially in the low temperature season in winter. CN1463589 discloses a method for cultivating ricefield eels in smal...

AI Technical Summary

Problems solved by technology

All methods also have many problems such as large water occupation, high bait coefficient, low output per unit area, short breeding cycle limited by seasons, heavy natural weight loss in winter, polluted water quality and high incidence of disease.

CN1418540 discloses a method for cultivating field eels in ecological net cages outdoors. The field eels are cultured in net cages in a culture pond. This method cannot guarantee the temperature of the water in the pond, especially in the low temperature season in winter.

CN1463589 discloses a method for cultivating ricefield eels in small soilless ponds. This method also breeds eels in the ponds. The water is stagnant and the water temperature cannot be adjusted.

CN101095402 discloses a method for ecological breeding of rice field eels. This method is to raise rice field eels in captivity, which also cannot solve the problem of water temperature required for cultivating rice field eels in winter.

CN2335371 discloses a kind of rice field eel factory farming equipment, which can flow water body, and can add oxygen to water body to disinfect and prevent turbidity, but it has not yet solved the problem of water temperature regulation of cultured water
