Eel culture technology

People who grew up in the countryside must be familiar with Monopterus albus. This aquatic creature, which looks like a snake, is actually delicious, nutritious and has certain medicinal value. It is a very popular nourishing aquatic product on the table. Monopterus albus has strong vitality and is easy to transport, so it can be put on the market alive, and there is a certain market prospect for developing artificial culture of Monopterus albus. The artificial culture technology of Monopterus albus is briefly described as follows: it mainly includes the construction of Monopterus albus pond, the selection and stocking of Monopterus albus fry, artificial feeding and daily management. 1. Monopterus albus pond construction has strong adaptability to the environment. Some abandoned water bodies unsuitable for raising other fish and puddles and ponds unsuitable for planting crops can be used as eel ponds. You can also choose a place with plenty of water, ventilation and plenty of sunshine to build an eel pond. Monopterus albus pond is preferably rectangular in shape, with a depth of about1m. The area depends on the breeding scale, generally 20~50m2. The bottom, walls and gaps around the eel pond must be tightly blocked to prevent eels from escaping. The eel pond must have a water inlet, a water outlet and an overflow, so as to discharge sewage, change water and prevent the eel from escaping when the water level in the heavy rain pond rises. Every exit must be equipped with escape prevention facilities. In order to facilitate the growth of Monopterus albus, we can artificially imitate the natural environment in which Monopterus albus lives, such as throwing stones and roots in the pool or planting aquatic plants such as floating lotus in the pool. Two. Selection and stocking of eel fry At present, in the artificial breeding of Monopterus albus, the free-range eel fry must be harmless, disease-free, healthy and smooth, with golden yellow as the best. Generally, about 80 eels per kilogram are selected. The small size of eel fry will affect its food intake and weight gain, so it can't be harvested that year. The stocked eel fry must be neat in specifications and consistent in size. Remember to mix the sizes to prevent the same kind from eating each other. Stocking density: about 10g of eel fry can be stocked per square meter. The effect of stocking eel fry in early spring is good, which is beneficial to feeding eel early and prolonging the growth period. Thirdly, farmed Monopterus albus is a carnivorous omnivorous fish with a wide range of food sources. Such as small fish and shrimp, earthworms, animal viscera and leftovers, snail meat, rice, melon skin, vegetable leftovers and so on. Monopterus albus should be fed regularly, at a fixed point, qualitatively and quantitatively. In other words, feeding eels after dusk and setting a fixed place to feed eels are beneficial to feeding eels at fixed points, which is convenient for us to observe the feeding situation of eels and clean up the residual bait. The bait should be fresh and fresh. The daily food intake of Monopterus albus is about 6% of the body weight of Monopterus albus. When feeding, it should be properly adjusted according to the eating situation of Monopterus albus the day before, and it is advisable to have a little surplus after feeding. Do not feed Monopterus albus for a long time or a short time, otherwise it will affect the growth of Monopterus albus.
