Pool-based eel cultivation method

Abstract

The invention discloses a pool-based eel cultivation method. The cultivation method comprises the following steps: (1) requiring a pool and cleaning the pool, namely, digging a fish pond ditch being 3m in width and 0.6m in depth, then building a long pond being 3cm in width and 0.6m in depth with bricks, paving a draining pipe being 70mm in diameter on the bottom of the pond, then building a small pond with bricks at every 4 to 5m in the middle, arranging an escaping-preventive net at the opening of the draining pipe, arranging a water feeding pond being 50mm in diameter on the pond, respectively distributing the draining pipe and a water feeding pipe at each side, then covering the walls of the built pond with a layer of plastic film which is as thick as 12 silks; (2) charging fish fries into the pond, namely, charging eel fries from April to August in general, wherein each eel fry is 50 to 80g, and 2 to 2.5kg eel fries are cultivated per square meter; before charging the fish fries into the pond, disinfecting with 5% potassium permanganate solution, screening out sick and injured eel fries, and then individually charging and cultivating by size; (3) feeding the eel fries, namely, crushing earthworm, fly maggot and fish, and then mixing with water to attract and feed the eel fries.

Description

technical field [0001] The invention relates to a cultivation method, in particular to a cultivation method for raising eels in ponds, and belongs to the technical field of cultivation. Background technique [0002] Swamp eel, also known as eel or long fish, has tender meat, delicious taste, less bone spurs, rich in protein, a variety of vitamins and minerals. Swamp eel also has important medicinal functions, such as invigorating qi, nourishing blood, reducing inflammation, and disinfecting. , controlling wind and dehumidification and other effects. At present, it is increasingly favored in the domestic and foreign markets, and the supply is in short supply. Rice field eel has strong adaptability, resistance to low oxygen and hunger, and is easy to transport. Its breeding method is simple, low in cost, and high in economic benefits, and is suitable for small-scale family farming. In the next 5 years listed by the State Information Center, 6 farming projects with great deve...

Problems solved by technology

The wild eel resources are limited. With the improvement of people's living conditions, the demand for eels has risen sharply. Wild fishing is difficult to meet the needs of farms. This requires large-scale artificial breeding of rice field eels.

Since the artificial breeding of eel has not been completed, all eel species are caught in the wild. Wild eels live in the natural state for a long time, mainly preying on live fish, live shrimp, python mussels, and water maggots. It is difficult to achieve these conditions in artificial large-scale breeding, so it is necessary to domesticate eels to eat and artificially formulate feed. The eels have just been raised in artificial ponds, and it is difficult to adapt to the environment. It takes a long time to gradually adapt to changes. It takes time, so it is difficult for small eel species to reach the market specifications in the first year, and they must be bred in the second year before they can be marketed
