The market prospects for farmed catfish are broad. What feed is generally used to feed farmed catfish?

Catfish can be fed with compound feed made of water fleas, water earthworms, cooked pig blood, fish meal, silkworm pupae, rapeseed cake, etc. Catfish have small eyes and poor vision. They hide during the day and come out at night. The growth cycle of catfish is about 3 months, that is, about 80 days. The breeding methods can be referred to as follows: fish fry and fish fingerling cultivation. Catfish fry and fingerling cultivation can be cultivated in cement pools, upper pools or cages. The area of ​​the earthen pond should not be too large, generally 100-500 square meters is appropriate. It hunts by smell and two pairs of tentacles. It is very greedy. The hotter the weather, the more it eats. It is active frequently on cloudy days and at night.

When catfish fry are just hatched, they usually rely on their own yolk as a source of nutrition. When they can swim normally, they can be fed with boiled egg yolk or plankton. Ponds are the most common way to raise fish in rural areas, especially in mountainous and hilly areas. Generally, a dam is built in the low-lying area at the foot of the mountain or on the hillside of the middle tribe, and a small pond is built. This can be used to raise fish and irrigate downstream farmland during the dry season.

Fish feed includes three main categories: powdered feed, granular feed (granular feed has soft granules and hard granules), and expanded (floating) granular feed. There are also micro-capsule feed, farm grain feed, etc. Since the water fry are put into the pond, feeding usually starts on the second day. Since the water fry have poor active feeding ability, they are usually sprinkled with soybean milk. Some of the fine soybean milk can be directly eaten by the water fry, and most of it is used to fertilize the water.

First of all, it depends on the species you choose. The ingredients are based on the nutritional structure required by the fish species. There are also different growth periods and different nutrients required. Therefore, raising fish well is a technical job and a tiring job. First, in general, you should choose feed from high-quality manufacturers. There are many companies making feed now, both small and large. The feed from high-quality manufacturers has strict material selection and process flow from raw materials, processing, and transportation.

Catfish can be fed with compound feed made of water fleas, water earthworms, cooked pig blood, fish meal, silkworm pupae, rapeseed cake, etc. Catfish have small eyes and poor vision. They hide during the day and come out at night. They hunt by smell and two pairs of tentacles. They are very greedy. The hotter the weather, the more they eat. They are active frequently on cloudy days and at night.

Catfish generally eat compound feed made of water fleas, water earthworms, cooked pig blood, fish meal, silkworm pupae, etc. The water quality can be fertilized about 7 days before stocking the fry. Some plants similar to water lilies can be planted on the water surface, which can provide shade. The residual water in the fish pond generally needs to be replaced every 10-15 days, and generally 1/3 of the water volume is enough. When the water quality is yellow-green, it means that the water quality is relatively good. When you find that catfish often jump out of the water, you need to turn on the oxygenation equipment in time.

Cooked egg yolk or small cladocerans and copepods are used as the initial food for the fry. As the fry continue to grow, they can be fed with water fleas, mosquito larvae, earthworms, fly maggots or pig blood, artificial fry compound feed, etc. In the early stage of fry cultivation, animal feed is mainly fed. When the fry grow to 5-7cm, they are trained and gradually switched to plant feed, combining animal and plant feed to ensure balanced nutrition. Feed feeding follows the "four determinations" principle. The daily feeding amount is controlled at about 5-8% of the total weight of the fish school, and the feeding amount is adjusted every 7-15 days.

When breeding catfish, the feed is mainly based on stool animals. You can feed some water fleas, brother coarse He or cooked pig blood fish meal, water earthworms, silkworm pupae, rapeseed cakes, etc. to make compound feed

What kind of feed do catfish feed, and what are the breeding conditions and requirements?

Farmed catfish are generally fed with compound feed made of water fleas, water earthworms, cooked pig blood, fish meal, silkworm pupae, etc. The water in the fish pond generally needs to be replaced every 10-15 days, and generally 1/3 of the water volume is sufficient. During the breeding process, the feed should be fed reasonably, and the feed should not be too much each time to avoid the catfish eating too much and blocking the esophagus. In addition, the feed fed to catfish during the seedling stage should be chopped.

1. What kind of feed do catfish feed?

1. Artificially bred catfish mainly eat compound feed made of water fleas, water earthworms, cooked pig blood, fish meal, silkworm pupae, etc. You can start fertilizing the water quality about 7 days before stocking the fry. Fertilizing the water quality is relatively simple. You can plant some plants similar to water lilies on the water surface, which can not only fertilize the water quality but also provide shade.

2. The water in the fish pond must be replaced every 10-15 days. The amount of water changed each time is 1/3. When the water quality is yellow-green, it means that the water quality is good, and there is no need to optimize the water quality. When catfish are found to frequently float to the surface, it is necessary to turn on the oxygenation equipment, because when fish have this reaction, it means that they are lacking oxygen.

3. During the breeding process, the feed must be reasonable. The amount of feed each time should not be too much. If the catfish eats too much, it will easily block the esophagus. When feeding catfish in the seedling stage, the feed must be chopped up, which is conducive to the feeding and digestion of the young fish. At the age of 2 months, you can feed them granular feed. In order to ensure balanced nutrition, you can also add some protein to the feed.

2. Catfish farming conditions and requirements

1. When breeding catfish, there must be a clean water source. Try to build a pond in a place with sufficient running water. The water retention of the pond must also be good and it must not be permeable. You can plant a moderate amount of non-spreading aquatic plants in the pond, which can provide a habitat for catfish.

2. Two weeks before stocking catfish, the water in the pond must be drained, and then the entire pond must be cleaned with quicklime solution, and then soaked in water for 1 week to clean the pond. Fill the pond with clean water and soak it for 2 days before stocking. Before stocking, the fry must be soaked in light salt water or other disinfectant solution for 20 minutes for sterilization.

3. Generally, 20,000 fry can be placed in one acre of pond. The size of the fry must be uniform, and they cannot be too large or too small to avoid uneven growth. The time of placement should also be noted. It is generally better to place them at noon when the temperature is suitable, so that the fry can easily adapt to the environment.

4. You can start feeding the fish a few hours after putting them in. You can make some grain into powder, then mix it with water and knead it into a ball to feed the fish, so as to avoid it becoming loose too quickly. You can also feed it some shell meat and snail meat, but it must be chopped before feeding it to the fish.

5. You can also fertilize the water and cultivate natural bait for fish to eat. Be sure to change the water in time and keep the water flowing. Prevent the fish from escaping on rainy days. Pay attention to oxygenation in hot weather to avoid fish from hypoxia and keep sufficient oxygen in the water.
