How to keep a catfish alive for a longer period of time 10

1. Put the catfish in a tank filled with water, preferably with tap water for two days before use, to remove chlorine (for tap water disinfection). Catfish are resistant to pollution and do not like sewage, and a clean environment is more conducive to their growth.

2. Change the water every 3-5 days.

3. You can feed catfish, small shrimp, loach, small snails, etc., and sometimes eat some fine aquatic plants.

Catfish, same as catfish.

There are many species, and the common ones are catfish (native catfish), largemouth catfish, and bearded catfish (pond catfish).

Leather-bearded catfish (Egyptian bearded catfish) Hakka is commonly known as slippery fish. Catfish, Animalia - Chordates - Subphylum Chordates.

Radiata-Catiformes-Catfishes-Catfish species. There are a total of 4 whiskers on the mouth, long at the top and short at the bottom, carnivorous, mostly wild, with low requirements for water quality, and can be artificially cultivated. The growth rate is relatively fast, and some varieties can grow to a large size.

Within a week, even if you don't have to feed anything, it won't die, because catfish are very durable, and it's often better not to feed them than not to feed them.

As long as the water has not passed the body of the fish, the tap water should be dried first.

Adult fish breeding monoculture: the fish pond is acre, the water level is meters, the water source is sufficient, and the fish pond is equipped with a drainage door, which is convenient for adjusting the water quality.

Fingerlings size 50 100 grams, 5 per square meter, seedling release time at the end of June and beginning of July. The proportion of bait is 30% fishmeal, 30% trifen, 10% bran, 20% vegetable cake, 10% cornmeal, 3 times a day, 1 time in the morning, afternoon and evening. Daily feeding 5 months in 6 months accounts for 5% of body weight, 7 months in 8 months accounts for 6% of body weight, 9 months in October accounts for 10% of body weight.

Daily management: Strictly prevent the death of hypoxic floating heads in the fish pond. Add new water once every 7 to 10 days.

Timing, qualitative, quantitative, fixed-point feeding. Regularly check the growth and plumpness of the fish, analyze and formulate measures for the next segment.

The body is elongated, with a flattened head and a flattened tail.

Subordial, the mouth fissure is small, and the end only reaches below the anterior edge of the eye. The lower jaw is prominent. The teeth are fine, villous, the jaw teeth and pear teeth are arranged in a curved band, the pear bone tooth band is continuous, and the middle of the posterior margin is slightly concave.

The eyes are small and covered with epithelium. Adult fish should have 2 to 4 roots, the upper jaw should be deep to the end of the pectoral fin, and the lower jaw should be shorter. The juvenile stage of catfish is 3 pairs, and when the body length reaches about 60 mm, 1 pair of chin whiskers begins to disappear.

Catfish are mucus and have no scales. The dorsal fin is small, without hard spines, and has 4 or 6 rays. Fat-free fins. The anal fin is very long, and the posterior end is attached to the caudal fin. Catfish are usually black-brown or grayish-black in color with slightly dark cloud-like patches.

Catfish do not freeze to death in winter. When the temperature begins to drop after autumn, catfish will spend the winter in deep water or burrowing into the silt, and will not go out to feed during the winter, and generally will not swim if there is no infestation in the shed.

Tropical catfish introduced ——— Egyptian pond catfish.

This catfish grows quickly but is sensitive to temperatures.

Below 15°C, there is basically a risk of freezing to death, and once it falls below 5°C, the chain cherry blossoms are likely to die in large numbers!

Recently, the temperature in Hubei has dropped a lot, and the night temperature in some areas has even reached below 0 °, and it is reasonable that these "tropical catfish" have died in groups.

It was hard to freeze to death, and when spring came he was alive again.

1. Fish pond construction.

Before farming catfish, we need to consider the location and construction of fish ponds. Under normal circumstances, we should choose to build the pond in a relatively quiet area with sufficient water source and non-polluted water quality. Secondly, we carry out the construction of fish ponds according to the topography of the selected fish ponds, and reasonably plan the area of the fish ponds according to the scale of aquaculture.

The depth of the fish pond is about one meter two, and the drainage pipe and water inlet pipe should be done in the fish pond. Finally, after the fish pond is built, it should be fully cleaned and disinfected, usually using quicklime, and then injected with new water after the disinfection is completed, waiting for breeding.

2. Select seedlings and put seedlings.

There are a lot of catfish fry in the market, but it's best to go to a regular place to pick them. When selecting the fry, try to observe as much as possible to see whether the appearance of the fry is injured, the activity of the fry and the feeding of the fry, etc., and then select the strong, disease-free, uniform and relatively uniform fry of size. Before releasing the fry, we need to disinfect the fry, and before the fry are released, we must carry out trial breeding, if there is no problem with the trial rearing, we can officially release the fry.

The last thing to pay attention to is that when putting seedlings, the density should be reasonably controlled, generally 70 or 80 fry per square meter, and no more than 100 fish fry should be put at most.

3. Water quality management.

Water quality management in fish ponds is very important when farming, so we must pay great attention to it in the process of farming. First of all, we need to ensure that the water quality in the fish pond is clean and clean, so under normal circumstances, we need to change the water every ten days and half a month, but in order to maintain the fertility in the pond, we can retain 30% of the old water every time we change the water. There is also the fact that when the catfish often jumps out of the water, it means that there is a lack of oxygen in the water, and it needs to be injected with salary, and the right amount of oxygenator can be put in.

Finally, we can also plant some duckweed, algae and other plants in the fish pond, which can also play a role in purifying the water.

4. Feeding management.

We also need to have professional feeding management techniques when we breed catfish. First of all, we need to choose high-quality feed, and we can't be greedy for cheap and ignore the quality of feed. The second is that we should be timed, positioned, and quantified in the recognition of feed, and generally feed in the morning and afternoon every day.

After the catfish is eaten, we need to clean up the feed residue in time to avoid polluting the water quality. It is also necessary to take measures to prevent pests and diseases, so as not to cause serious losses due to disease problems.

Catfish is a relatively long-lived fish. They can live up to around 70 years old under normal grip and talk to some long-lived individuals can live up to around 100 years. However, catfish in daily life generally do not live for that long because there are many factors that can cause their lifespan to be shortened.

Catfish are demersal ferocious fish. Afraid of light, he prefers to live in stone crevices, deep pits, soil or stone holes at the base of tree roots, and slow-flowing waters. In the still water of the water section of the oak reservoir, ponds, lakes, and weirs, there are mostly shaded bottom layers or patches of floating lotus.

Water peanuts, water hyacinth.

Below. In the spring, they begin to move and forage. It does not eat after winter, lurks in deep water or burrows for the winter, and generally does not swim if there is nothing to disturb it.

Catfish have small eyes, weak eyesight, nocturnal and nocturnal, hunt for food by their sense of smell and two pairs of tentacles, and are very gluttonous, the hotter the weather, the greater the amount of food, on cloudy days.

and frequent nocturnal activity.

You can mix a little water, it's okay, it's best to feed more earthworms.

Hello answer. Catfish is easy to raise, catfish has a strong ability to adapt to the environment, but the water quality of breeding catfish should be clear and not polluted, disinfect the pond before putting it, choose healthy and disease-free high-quality fish fry to be put in, ensure that the feed feeding is scientific and reasonable, do a good job in breeding management and disease prevention and control in a timely manner, do a good job of patrolling the pond every day, add water and oxygen in time, and promote the growth of seedlings.

Catfish, also known as soil catfish, mostly lives in the middle and lower layers of rivers, lakes, reservoirs, and pits and ponds, and is a carnivorous fish, which is the most widely distributed fish in the catfish family. They are not very demanding to the environment and have strong adaptability, so it is relatively easy to breed.

Question: Is it easy to raise catfish in fish ponds, thank you!

Ask questions to increase oxygen.

It is impossible to say that there are only ten or twenty fish ponds in one fishpond.

Question: Is it okay to raise 400 of half an acre of mountain pond with a water depth of two meters? Thank you!

Question, thank you, goodbye!

Disease-free source pond, the size according to your situation, directly release the water, go to the slaughterhouse to buy something they don't want and throw it in, five or six days can put fish fry, very good to raise, they basically eat everything, animal carcasses are the best food,

First, the silver carp is slaughtered into blocks, with sweet potato flour, a little salt, pepper, cooking wine (beer, white wine can be) code flavor (to remove the fishy smell, make the fish more tender and tender) in the pot is poured is a large cooking oil, add bean paste, ginger and garlic slices, chili noodles, spicy sauce, green and red dried peppercorns, stir-fry until fragrant, add appropriate water to boil the fish, in seasoning, depending on your taste (salt, monosodium glutamate, chicken essence, a little cooking wine... Finally, hook the gourd (sweet potato flour or cornstarch can be used), sprinkle with chopped green onions, and the delicious catfish will be ok pull @
