1, fish tank conditions: When breeding pond horn fish indoors, you need to prepare a clean fish tank, clean it and dry it. 2. Frequency of changing water: The water quality of artificially cultured pond horn fish must be kept clean. If the water is turbid, it will affect the survival rate of fry. 3. Feeding food: If you want the pond horn fish to grow healthily, you should provide them with food rich in protein during the feeding process. 4. Cleaning up the residue: In the process of indoor culture of pond horn fish, it is necessary to clean up 1 time of dirt every day.

First, indoor artificial culture technology of pond horn fish

1, fish tank conditions

(1) When breeding pond horn fish indoors, be sure to prepare a clean fish tank, then clean and dry it, and finally inject clean river water.

(2) Aquatic plants can be planted at the bottom of the fish tank, which can create a good growth environment for the pond horn fish.

2. Water change frequency

(1) The water quality must be kept clean when the pond horn fish is cultured artificially. If the water is turbid, the survival rate of fry will be affected.

(2) In summer when the temperature is high, it is necessary to change the water every 15 days, so as to ensure the oxygen content in the water and avoid the disease and death of the pond horn fish.

3. Feed food

(1) If you want the pond horn fish to grow healthily, you must provide them with foods rich in protein, such as fish, shrimp, soybean milk and bean dregs.

(3) Feed 1 time every morning, noon and evening? Don't feed too much to prevent the pond fish from swelling.

4, clean up the residue

(1) When the pond horn fish is cultured indoors, the dirt should be cleaned once a day, and the remaining food residues and aquatic leaves should be salvaged.

(2) This can avoid the stink and deterioration caused by soaking in water for a long time, and make the pond horn fish infected with diseases.

Second, what is the feed for Tangjiao fish?

1, Tangjiao fish is also called Silurus meridionalis. It is an omnivorous fish, which can eat both animal feed and plant feed. It mainly feeds on small fish, shrimp and some aquatic insects, and it can also feed on discarded scraps and animal carcasses from slaughterhouses. In artificial breeding, it can be fed with animal feed such as silkworm chrysalis and fly maggot, and can also be fed with plant feed such as peanut cake and rice bran.

2. Feed formula of Tangjiao fish: 45% fish meal or silkworm chrysalis powder, 20% peanut bran, 20% flour, 0/0% rice bran/kloc, 3% bone meal or shell powder, and 2% fish vitamins and minerals. Tangjiao fish eat a lot, and can eat 5%-8% of their own weight every day.

3. The requirements of pond horn fish are relatively low. As long as the pond foundation is solid and there is no leakage, it can be used as a single pond for pond horn fish after transformation. The water source of the pond must be sufficient, with good water quality and large area, and it should be prepared before stocking. For example, before stocking fish, the pond water must be drained and exposed to the sun for 3-5 days. After simple trimming, the pool can be completely disinfected with quicklime, and the dosage is 50-75 kg per 0.067 hectare.
