What is the method for breeding eels in a still water pond? What should be paid attention to?

Still water pond eel farming refers to a method of raising eels in a specially built pond or by reusing a wastewater pond. Its characteristics are small water exchange, mud at the bottom of the pond for eels to dig holes or artificial caves, and most of them are specialized eel farming.

(1) Construction of eel pond

This is the general method of pool construction, which has been introduced before.

(2) Stocking of young eels

Before young eels enter the pond, two preparations must be made: disinfection of young eels and disinfection of eel ponds. Before young eels enter the pond, they must be soaked in a solution made of medicine to kill parasites and bacteria on the body surface and prevent them from spreading in the eel pond. Add 10 grams of malachite green per cubic meter of water, soak for 25 to 30 minutes at a water temperature of 24 to 26 degrees Celsius, or soak for 5 to 10 minutes in 3% to 4% salt water.

(3) Eel feed

When raising eels artificially, the bait should be adjusted to local conditions and collected through multiple channels. In areas with abundant natural waters, small fish, shrimp, tadpoles, snails, river clams, etc. should be caught or purchased at low prices; in areas with concentrated farmland, the phototaxis of insects can be used to install black lights on eel ponds at night to trap flying insects. Larger farms can arrange special ponds to artificially cultivate live bait (there is a special link behind this).

(4) Breeding and management

The growing season of the eel is from April to June, and the peak feeding season is from May to September. The following points should be noted during the breeding process of the eel.

① Feeding: The amount of feed for eels should be determined according to the type of bait, water temperature, water quality and other conditions. Generally, it is 3% to 4% of the total weight of the eels in the early stage, 5% to 7% in the middle stage, and reduced to 3% to 4% in the later stage.

② Water quality: Maintaining good water quality is very important for raising eels. Therefore, in the hot season, the frequency of water changes should be increased, from once every 3-4 days to once a day. When changing water, pay attention to the temperature difference and remove the remaining bait in time. Planting aquatic plants in the pond water can also play a role in purifying water quality.

③ Prevent escape Adult eels are large and have strong escape ability. Therefore, it is necessary to regularly check whether the plastic nets or wire meshes on the inlet and outlet are intact, and repair them in time if any holes are found. On rainy days, excess water should be drained in time. This can prevent escape and facilitate the breathing of eels.

④ Pest prevention: The water in the pond for breeding eels is shallow, and livestock and poultry can easily enter and prey on them, so appropriate preventive measures should be taken.

(5) Arrest

The time to catch eels for breeding is generally from late October to early November, when the water temperature is 10-15℃. At this time, the eels have basically stopped eating and growing; they are less active, so they are not easily injured when caught, and they are also easy to transport. The time to catch is chosen at night. First, use a hand scoop net to scoop up the eels. When they are almost caught, drain the water and then catch them by hand. If necessary, the bottom mud can be removed.

First of all, you need to provide a good breeding pond, then disinfect and sterilize it, and pay attention to the disinfection of the soil, and then put some eels in the soil, so that you can breed better. To do this, you must pay attention to the hardness of the soil, the moisture of the soil, the cleanliness of the water source, and the prevention of diseases.

The pond eel farming method refers to a method of raising eels by building a special pond or reusing a wastewater pond. Its characteristics are small water exchange, mud at the bottom of the pond for eels to dig holes or artificial caves, and most of them are specialized eel farming.

The still water pond method of raising eels refers to building a special pond or utilizing a wastewater pond for modification. It is theoretically feasible to use ecological methods to carry out still water soilless breeding of eels. It can be cultured indoors or outdoors; it can be cultured in fresh water or in saline-alkali land. After the cement pond is built, it must be de-alkali treated. The key to successful eel farming is the quality of the seedlings.

In rural areas, why do people put a few eels in paddy fields and ponds near houses?

It may not be put in there intentionally, most likely it just flowed out with the water. Both eels and loaches have auxiliary respiratory systems. Eels can use the epidermis of the inner wall of the mouth and throat as auxiliary organs for breathing. They can breathe air directly. After the water is released, as long as the skin is kept moist, they will not die within a few days. Loaches can swallow the air in the rectum to help them breathe. These two fish are also very drought-resistant and can make holes.

Similar to snails, they can also stalk the ground if there is more rainfall in the area and the shallow soil can remain moist. These animals also have the ability to transport food. Rice fields are usually not far from natural water bodies. When it rains, they can move from water bodies such as reservoirs to rice fields. If the precipitation is enough to directly connect to other water bodies, it can allow other animals with weak drought and oxygen resistance to enter the rice fields. So for the question, "Can I keep these eels in a bucket of water and mud", my answer is possible.

In water and soil samples collected from the wild, eggs, larvae, and even adults of these organisms can be included. If the nutrients in the environment can help you reach a size that can be observed, it can be regarded as "improving ability". But there is a clear point here, that is, the so-called "included", not that the environment of water and soil produces these organisms from nothing, but that water and soil contain these organisms that can survive and survive. They develop in the environment you provide.

This problem can also be used as a comparison: Treat soil and water with high temperatures to completely kill the organisms inside (preferably to a temperature that kills spores), and then put it into a completely closed environment. In this case, it will not have anything alive. This idea is actually a famous experiment by Pasteur in the field of biological sciences.

The first benefit of putting eels in paddy fields or ponds is that it can prevent water from drying up, because water is the most indispensable thing for paddy fields and ponds. People usually raise some fish in their own ponds for food. Once the pond dries up, the fish will die. Because eels like to dig holes, they can connect the groundwater with the water in the pond, which can prevent the pond from drying up.

The second benefit is that they can eat some snails in the pond to prevent snail infestation and eat pests in the paddy field. This is because snails have a very strong reproduction ability in the pond in the absence of natural enemies. Too many snails will cause the fish in the pond to grow slowly, and the eel likes to eat small snails, so this can effectively prevent snail infestation. Secondly, if you put the eel in the paddy field, it will eat some pests that harm crops in the paddy field, thereby protecting the crops.

This is because we need to maintain the balance of this small ecosystem.

This is because by doing so, it is able to keep the water clear.

This is economical. Not only can we eat the fish when they grow big, but it also makes the water better.
