1.Fish pond conditions: an area of 2-5 acres, water depth of more than meters, every 1-3 acres equipped with a water wheel aerator for eel farming, with anti-escape facilities.
There is an abundance of fresh water. 2.Water Quality:
pH, dissolved oxygen in water more than 3 milliliters, high temperature, high density when deepening pool water. 3.Stocking density:
3 cm fry, 12,000-15,000 per mu; 5-7 cm fry, 8000-12000 per mu; More than 10 cm fry, 6000-10000 per mu. 30-50 bighead carp above catty and 10-20 silver carp above kilogram per mu. Fish Disease Prevention:
Before the seedlings are released into the pond, they should be soaked in 3%-5% saline for 3-5 minutes, or potassium permanganate or dysenteric soaked in the bath for disinfection. When clearing the pond, 100 kg of quicklime is used to disinfect, and baking soda (sodium bicarbonate) is usually used to adjust the pH, and the dosage is used for catties with a water depth of more than 1 meter per mu, every 20-30 days. During the grow-up period, disinfect the water body with chlorine preparations every 15-20 days to prevent diseases.
Bait feeding: 10 cm below the fry cultivation, fish flower to fertilizer underwater pond best, after 1-2 days on the shore to sprinkle eel slurry, after 3-5 days, in the pond on one or both sides every 5-6 meters with a plastic plate as a feeding table, the eel (lumpy) or bloodworms placed on the table, the food table is located 20-30 cm below the water surface, so that the fish let free to eat. As the fish grows, gradually reduce the food table, and the bait on the food table should not be too much at a time, feeding 5-8 times a day.
More than 10 cm to the market stage to use the pond lice puffed material, can achieve the desired effect. Local pond lice are shade-loving and light-sensitive, so it's best to feed before 8:30 a.m. and at 6:00 p.m. in the afternoon
00 or so feeding, 2-3 times a day; Each time it takes 20-30 minutes to eat. If the weight of each tail is less than 50 grams, the feeding amount is 5%-8% of the body weight, and the weight of each tail is more than 50 grams is 3%-5%. The morning material accounts for 60%-65% of the whole day, and in the afternoon it accounts for 35%-40% of the whole day, so as to facilitate the fish to digest and absorb more fully.
Precautions: The local pond lice are warm-water fish, the most suitable temperature is 25-30, when the water temperature is higher than 32, it is easy to cause fulminant fish disease, and special attention should be paid to it. In June-September, when the temperature is high and the sun is fierce, 1 p.m
At 00-3:00, the aerator should be continuously or intermittently turned on for 1-3 hours to facilitate aeration, water diversion and water temperature, which is an important measure to increase the production and prevent diseases of local pond lice. In the middle and late stages of aquaculture, water hyacinths accounting for 5%-10% of the pond area can be kept in captivity.
Every 10-15 days, fill with 10-30 cm of fresh water in the morning or noon.

In the usual feeding management, we should apply organic fertilizer reasonably according to the fertility of the water body, cultivate sufficient plankton, and increase natural feed. The second is to change the water frequently, generally every half a month or so, to prevent the deterioration of water quality, of course, if the temperature is high, we need to adjust the water change cycle according to the situation. There is also a need to regularly disinfect the breeding pond, generally every half a month to about 20 days with quicklime disinfection.
The last is to carry out patrol = pond management, check the growth and activity of pond catfish, keep abreast of weather changes, and take protective measures.
-
The pond area is generally 600-2000 square meters, and the water depth is meters.
Fingerlings stocking. The stocking of fish fingerlings specifications are consistent, stocking density depends on the size of the fish species and ponds, feed, water conditions, generally 5-10 fingerlings of about 10 cm per square meter. The stocking of large-sized fingerlings increases survival rates and production.
The size of the fish fingerlings in the lower pond should not be less than 5 cm.
Feeding. When the fingerlings are just out of the pond, they should be fed some high-quality animal feed to make them recover their physique and accelerate their growth as soon as possible. Leatherbeard catfish is an omnivorous fish based on animal feed, such as snails, clams, mussels, snails and other shellfish, as well as maggots, silkworm pupae, earthworms, animal carcasses and scraps.
Shellfish should be fed after breaking the shell, and the tougher ones need to be broken or ground into a pulp to make a food ball to improve the utilization rate. Powdered feed (fish meal, bone meal, shrimp shell meal, corn meal, rice bran, wheat bran, etc.) is best mixed with meat. Conditionally, according to the nutritional needs of the leatherbeard catfish, it can be prepared into pellet feed with a crude protein content of more than 30%, which can not only improve the feed utilization rate but also accelerate the growth of fish.
Feed should be on the feed table. The feed should be fine and coarse, and the feed should be cast once a day in the morning, noon and evening, and the feeding should adhere to the "four determinations".
Proper application of organic fertilizer to cultivate zooplankton can meet the feeding needs of leatherbeard catfish and reduce the feed coefficient.
Day-to-day management. Clean the feed table frequently to keep the water fresh and prevent the fish from being hypoxic due to high density. The water should be filtered to avoid introducing predators such as parasites.
It is also necessary to prevent snakes and rats from burrowing and escaping fish after rain, and usually patrol the pond to check whether there are loopholes and whether the fish blocking facilities are damaged.
2) Pond polyculture. Polyculture of leatherbearded catfish with other fish can make full use of the water space and give full play to the potential of pond production. It can also be used to remove wild trash fish from ponds and to control the overgrowth of tilapia.
Leatherbeard catfish can be polycultured with chains, bighead carp, carp, grass, tilapia and other fish, but not with carnivorous fish. The size of the fish fingerlings of polyculture should be appropriately larger, and it is best to reach the commercial specifications in that year, and can be dried and marketed with the leatherbeard catfish. Polyculture methods are:
Mainly leather-bearded catfish, with other fish: generally stocked with 5-6 cm of leatherbeard catfish fingerlings per square meter, and every 2-3 square meters with a domestic fish fingerling.
Mainly other fish, supplemented by leatherbeard catfish: in the adult fish pond that can feed domestic fish, every 2-3 square meters is raised with a leatherbeard catfish with a body length of 6-8 cm, and the use of small trash fish and aquatic insects in the water as its feed, without increasing feeding.
Polyculture of leatherbearded catfish broodstock in adult ponds: 1:1 or 1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:1:
A small number of reproducible leatherbeard catfish are placed in the breeding season, and the nests are released to allow them to spawn and hatch. According to the number of leatherbearded catfish that are bred, some animal feedings are appropriately fed, so that it can grow commercial fish directly in the adult fish pond. When stocking, the loading capacity of the water body after breeding should be considered.

Water lice belong to the class Crustacea of the phylum Arthropods. It is an aquatic crustacean, very small, suitable for feeding ornamental fish, and is also one of the important foods when raising ornamental fish.
Habitat: Inhabits still water or slow streams.
Exterior features: slender body, very light; The forefoot is short and can be used to catch prey; The middle and hind feet are elongated and have fine hairs with an oily texture, which is waterproof. The body color is dark brown and the body length is about 22mm.
It usually lives in groups and can be seen in some parts of southern China for many years. When the eggs are hatched, the nymphs sink to the bottom of the water first, and soon float to the surface, where they move quickly with the movement of other individuals, and die soon after laying eggs.

In April, it enters the ditch and valley areas from the wintering areas. From April to May, a circular digging of the nest is dug at the tail and reproduces in the nest. After the eggs are fertilized, the male leaves, and the female guards the cave to defend against the enemy until the larvae are able to swim and feed. 70-200 eggs are laid each time, and the spawning period is 2 times a year, in April-May and August-September.
In summer, when the water temperature rises, the catfish returns from the rice fields to the rivers and ditches, and swims to the rice fields from August to September for reproduction.
