The pond carp is a very famous fish and is loved by many aquarists. So how to raise the pond carp? Below is the method of raising pond carp that I have carefully compiled for you. Let’s take a look.

How to raise pond carp

In spring (March to May in the Gregorian calendar), the temperature gradually rises, generally between 10 and 20 degrees Celsius, and the water temperature environment is more suitable for the growth of various pathogens. Reproduction, especially April-May, is the peak season for fish disease---"barley yellow". When the fry hatch in early spring, the eggs are susceptible to saprolegnia; the fry are mainly susceptible to fish diseases such as trichozoa, melonworms, ringworms, trematodes, and fish lice; in spring, adult fish are susceptible to microbial fish diseases, such as viral hemorrhagic disease , enteritis, gill rot, printing disease, silver carp iodosporidiosis.

The temperature in summer (June to August in the Gregorian calendar) is generally between 26 and 28 degrees Celsius, and fish diseases are slightly less common than in spring. At this time, fish species gradually grow up and their disease resistance increases. Therefore, ciliates and flagellate fish diseases are gradually decreasing. In addition, according to surveys, spring microbial fish diseases continue to exist in summer, including gill rot, bleeding, red skin, enteritis, printing disease, etc. At this time, parasitic parasites such as worm disease are more common. In midsummer, high-yield ponds are often prone to pond flooding.

The temperature gradually drops in autumn (September to October in the Gregorian calendar), and the temperature is generally between 23-15 degrees Celsius. The water temperature environment is basically similar to that in spring, especially August to September, which is the peak season for fish disease-- - "Bailuxin", summer flower fish species are mainly affected by fish diseases such as trichozoa, melonworms, ringworms, flukes, fish lice and other fish diseases. In autumn, large-sized fish are susceptible to microbial fish diseases, such as viral hemorrhagic disease and enteritis. , gill rot and other diseases.

The temperature in winter (December to February in the Gregorian calendar) is low, generally between 3 and 6 degrees Celsius, and fish diseases generally rarely occur. Winter is the time for fish species to be stocked, and fish bodies are often scratched due to netting or transportation, and saprolegnia can also occur; when the water temperature is high, it is possible to produce clavicle disease and small melonworm disease; overwintering fish are affected by water temperature When the temperature is lower than 10 degrees Celsius, due to the large temperature difference between the overwintering room temperature and the water temperature, the fish will suffer from frostbite on the top of its head when it floats due to lack of oxygen.

As the temperature changes in spring, summer, autumn and winter, there are currently 12 kinds of common fish diseases, among which there are 7 main kinds of parasitic diseases: trichozoa, melonworm, ringworm, and anchorhead disease. , fish lice disease, silver carp iodosporidiosis, Chinese worm disease; there are 5 main types of microbial diseases: hemorrhagic disease (red skin disease), enteritis, gill rot disease, printing disease, and saprolegnia. As the saying goes: "If you raise fish, you will not get sick, but if you are rich, you will be dizzy." In the production of fish farming, once fish diseases occur, the mild cases will affect the growth and development of fish, and the severe cases will cause the death of some fish. Therefore, we must pay attention to the prevention and control of fish diseases and actively implement the "No Disease Early Prevention". The policy of early treatment of diseased animals

The head of the female Anchocephalus worm burrows into the host's muscles, causing tissue damage, inflammation, and ulceration. Sick fish are restless, have loss of appetite, become emaciated, and swim slowly. Fish species with a size of 6-10 cm may become deformed and lose their balance. The insects exposed outside the fish often have protozoa, algae and mold attached to them. When the infection is serious, the fish will appear to be covered with a coir raincoat, thus increasing the burden on the fish and affecting the diseased fish. activity ability. When there are a large number of parasitic parasites in the fish's mouth, the sick fish's mouth cannot be closed, and it cannot eat and die. For fish with smaller scales such as silver carp and bighead carp, the surrounding tissue is red, swollen and inflamed due to the parasitism of the anchorhead carp, thus forming pomegranate-like red spots on the skin. When the anchorhead eel parasitizes fish with large scales such as grass and carp, the scales at the parasitic site will be "wormed" into gaps, the scales will be lighter in color, and congested erythema will appear at the parasitized site, but the swelling is generally not obvious.

Inspect fish before stocking. If anchorhead eel parasitism is found, remove it first, then soak it with potassium permanganate before stocking. Techniques for raising pond squid

1. Biological characteristics of pond squid

Tang squid is a kind of fish that likes shade but fears sun, lives in groups and is bottom-dwelling, and mainly feeds on animal feed. omnivorous fish. In natural waters, it often feeds on small fish, shrimps, insects and carcasses of other animals in the water.

However, artificial breeding uses water earthworms, cladocerans or silkworm pupae, scraps from slaughterhouses, etc. It can also be fed with fish meal, peanut bran, corn flour, etc. to make artificial feed.

2. Breeding of pond lice

1. Fish pond requirements. The surroundings of the pond foundation must be firm, check for leaks and plugging, and separate inlets and drainage outlets to prevent the pond water from overflowing (over the foundation) during the rainy season, causing the pond lice to escape with the water.

2. Fish pond disinfection. Before the fry are stocked, the fish pond must be thoroughly cleared of debris and silt at the bottom of the pond. Use 25 kg of quicklime or 20 kg of tea seed bran per acre, or 5 kg of bleaching powder mixed with water and pour the entire pond for disinfection. After a week, the water will be tested to confirm that it is safe. Only then can seedlings be released.

3. Release fish fry. The cultivation of pond lice can be divided into two methods: polyculture and pure culture. Polyculture refers to the polyculture of 150 to 200 five-fingered fish per acre (about 200 fish per kilogram) in a pond that breeds four major species of fish. Normally, there is no need to put in special feed, and 15 to 25 kilograms can be harvested per mu. Pond lice; pure culture uses a solid pond foundation, convenient drainage and irrigation, and the water depth can be controlled at about 1.5 meters. The area... Pond lice, scientific name is catfish, commonly known as pond angler fish, because it has special medicinal value It tastes delicious and is one of the popular aquatic products among the masses. The value of Tangyu

Economic value
