How to feed farmed Monopterus albus to make it easier for them to be infertile?

I believe many people like to eat eels. It is delicious and nutritious, and is welcomed by many consumers. Now there are more and more eel farmers, and then Xiaobian will tell you about eel farming technology.

Key points of eel culture technology:

1, build an eel pond

Monopterus albus has strong adaptability to the environment. Some abandoned water bodies that are not suitable for raising other fish and puddles and ponds that are not suitable for planting crops can be used as Monopterus albus ponds. You can also choose a place with sufficient water and sunny ventilation to build an eel pond. Monopterus albus pond is rectangular in east-west direction, with a depth of about 1 m, and the area depends on the scale of culture, generally 20 ~ 50 square meters is appropriate. 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 port, so as to discharge sewage, change water and prevent fish from escaping when the water level in the heavy rain pond rises. Fishing facilities must be installed at each nozzle. In order to facilitate the growth of Monopterus albus, we can artificially imitate the natural environment for Monopterus albus to inhabit, such as placing stones and roots in the pool, or planting aquatic plants such as floating lotus in the pool.

2. Selection and stocking of eel fry

At present, the cultured eel fry must be harmless, disease-free, robust, smooth and golden in color. 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 cultured eel fry must have neat specifications and the same size. Stocking density: about 100 eel weight 100 eel can be stocked per square meter. The effect of stocking eel seedlings in early spring is good, which is beneficial to early feeding of eels and prolonging the growth period.

3. Daily management

In addition to feeding, the key points are to prevent Monopterus albus from escaping, improve water quality and do a good job in heatstroke prevention and wintering:

(1) escape prevention. Check and maintain the escape prevention equipment of eel pond frequently. In rainy days, especially in heavy rain, it is necessary to drain water in time to prevent eel from escaping from the drainage hole.

(2) Water quality management. In order to keep the pond water stable and fresh, the depth of eel pond water should be between 15-25cm, which can be deepened in high temperature season. When the weather changes suddenly (from rainy day to sunny day and then to rainy day) and it is sultry, fresh water should be injected in time to prevent eels from floating their heads frequently due to lack of oxygen, and water should be changed regularly. In hot season, water must be changed every day to clean up the residual food in time.

(3) Do a good job in heatstroke prevention and wintering. The suitable water temperature for the growth of Monopterus albus is 15-30℃, and above 30℃ will have adverse effects on food intake. Therefore, we must do a good job in heatstroke prevention in high temperature season and plant shade crops around the eel pond; Change the pool water frequently and inject well water or spring water in time (the temperature difference should not be too large). When the water temperature is below 10℃, Monopterus albus is in a dormant state, so when the temperature drops to about 15℃, we should feed high-quality bait to make Monopterus albus eat a lot and store nutrients for hibernation. When Monopterus albus hibernates, attention should be paid to keeping the mud in the pond moist and warm. Prevent eel from frostbite and freezing to death. In addition, we should pay attention to prevent the harm of rats and so on.

4. Artificial feeding

Monopterus albus is a carnivorous omnivorous fish with a wide range of bait sources. Such as fish and shrimp, earthworms, animal offal and scraps, tadpoles, silkworm chrysalis, snail meat, rice, melon skin, vegetable scraps, etc.

Feeding Monopterus albus should adhere to timing, positioning, qualitative and quantitative feeding. That is to say, we usually feed Monopterus albus after dusk, and set up a fixed feeding place for Monopterus albus, which is conducive to the fixed feeding of Monopterus albus, convenient for us to observe the feeding situation of Monopterus albus and clean up the residual bait; The bait must be fresh and alive; The daily feeding amount is about 6% of the body weight of Monopterus albus, which should be adjusted according to the feeding situation of Monopterus albus the day before, and it is appropriate to have a little surplus after feeding. Feeding Monopterus albus must not be long or short, otherwise it will affect the growth of Monopterus albus.
