Problems solved by technology

Because of its strong adaptability, less disease, high survival rate, strong fecundity, convenient transportation, and easy bait, rice field eel has become an important aquaculture species. At present, rice field eel in cage culture is becoming more and more popular, but cage culture Due to unscientific methods, the production of rice field eels is not high, and the taste is poor, which is difficult to meet market demand

Embodiment 1

[0019] A kind of method for cultivating rice field eel in net cage comprises the following steps:

[0020] (1) Cage specifications: the length of the cage is 4 meters, the width is 4 meters, and the height is 1 meter. The above-water part of the cage is 0.4 meters, and the underwater part is 0.6 meters; Aquatic plants are placed in ponds and net cages, and the covered area of ​​aquatic plants accounts for 90% of the net cage area; aquatic plants include water peanuts and green duckweeds. The setting area of ​​the cage shall not exceed 50% of the total area of ​​the pond. If the net cage is a new net cage, put the net cage into the pond and soak for 35 days before stocking the fry. The transparency of the water in the pond is controlled at 14 cm.

[0021] (2) Stocking fish fry: When the pond water temperature reaches above 15°C, stock 15 kg of ricefield eel fry per square meter of cages, and the specifications of ricefield eel fry stocked in each cage are the same; before fis...

Embodiment 2

[0025] A kind of method for cultivating rice field eel in net cage comprises the following steps:

[0026] (1) Cage specifications: the length of the cage is 5 meters, the width is 5 meters, and the height is 1.5 meters. The upper part of the cage is 0.6 meters, and the underwater part is 0.9 meters; the mesh aperture is 0.6 mm; the cage is set in a pond with a water depth of 2 meters Middle; Aquatic plants are placed in the cages, and the coverage area of ​​aquatic plants accounts for 95% of the cage area; aquatic plants include water peanuts and Ophelia. The setting area of ​​the cage shall not exceed 50% of the total area of ​​the pond. If the net cage is a new net cage, put the net cage into the pond and soak for 40 days before stocking the fry. The transparency of the water in the pond is controlled at 12-18 cm.

[0027] (2) Stocking fish fry: When the pond water temperature reaches above 15°C, put 20kg of ricefield eel fry in cages per square meter, and the specificati...

Abstract

The invention relates to the technical field of aquaculture, in particular to a method for breeding ricefield eels through net boxes. The method comprises the steps (1) net box dimensions; (2) fry putting; (3) feeding; (4) disease preventing and treating. According to the method, waterweeds are arranged in the net boxes to provide a better environment for the growing and inhabiting of the ricefield eels, the size of the ricefield eels put in each net box is the same to prevent the cannibalism among the ricefield eels, the mesh diameter of the net boxes is smaller, the threads of the net boxesare denser, the breaking of the net boxes caused by the biting of water rats resulting in the escaping of the ricefield eels is prevented, the hurting of the ricefield eels caused by leeches in a pondcan be reduced, feed is soaked by adopting potassium hypermanganate before being put into the net boxes, the breeding of pathogens can be reduced, the possibility of pathological changes of ricefieldeel fry is reduced, the survival rate of the ricefield eel fry is improved, the breeding risk is reduced and the economic benefit is improved; the protein content in the artificial mixing feed is high, the meat of the bred ricefield eels is fresh, the taste is good, and market demands can be well met. The method is scientific, reasonable, low in cost and suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating rice field eels in net cages. Background technique [0002] Rice field eel, belonging to Cyprinidae and Loach family, is a small economic fish and belongs to warm water fish. The growth water temperature is 15-30°C, the optimum water temperature is 22-28°C, and the water temperature is higher than 32°C when drilling into the mud. It dives into the mud and hibernates below 7°C. Rice field eels are omnivorous fish, which often feed on water fleas, silk earthworms, aquatic plants and microorganisms in water. They are often piled up with chicken manure, cow manure, pig manure and other methods to breed bait or feed artificial pellet feed to feed rice field eels. Rice field eel is a small freshwater fish with wide distribution, strong adaptability and low environmental requirements. It is one of the important aquatic products exported by my country's fore...
