1. Fish pond construction. Pondfish can be cultured in a small area of ??water, so the pond area can be selected according to actual conditions, generally 20 to 100 square meters, and the water depth should be at least 0.8 meters and not more than 1.5 meters. The bottom of the pond does not need to be watered with cement like a general fish pond, but some plastic pipes and buckets can be placed as a habitat for the pond fish. Some aquatic plants can also be planted in the pond. The main purpose is to cool down in summer, maintain heat in winter and improve water quality. However, be careful not to allow aquatic plants to breed too densely, otherwise it will affect the oxygen content of the water body.
2. Release seedlings. The appropriate density of fry is 800-1,000 fry per square meter. If you do not plan to divide the ponds later, you can put in less fry, reducing it to 100-200 fry per square meter. Before releasing seedlings, organic fertilizer can be piled around the pond to increase the organic matter content in the water, promote the growth of plankton, and provide sufficient food for the fry.
3. Fish fry breeding. There is generally no need for additional feeding in the first week after the fry are released, as the plankton in the water body can provide food for the fry. On the 8th day after the seedlings are released, silkworms or chopped fish, shrimp, etc. need to be fed. After one month, you can start feeding pig blood, chopped pig water, etc. At this time, you can also feed some plant feed. If you find it troublesome, you can continue to feed minced fish and shrimp. The main purpose of feeding during this period is concentrated feed, which is to help the fry develop quickly. Generally, the pond angler fish can grow to more than 3 centimeters after one month. At this time, ponds need to be divided, otherwise the breeding density will be too high, which will affect the survival and development of the fry. If you don't put too many seedlings in, you don't need to divide the pond.
4. Adult fish breeding. The most important thing in the cultivation of adult fish of Tangjiao is the feeding. Because Tangjiao has a mixed diet, diversifying feeds is beneficial to the growth of Tangjiao. If conditions permit, you can continue to feed pond fish, minced meat, rice bran, and soybean meal according to the standards of the fry stage, or you can only feed plant-based feed.
The feeding time should be based on the life habits of the pond fish. Feed every morning and evening. You can also feed it only once in the evening, but the amount of feeding this time should be sufficient. The specific amount of feeding depends on the stocking density. You can observe the remaining feed after feeding and increase or decrease as appropriate.
5. Daily management. Tangjiao fish have a strong constitution and generally do not get sick, but they still need to do a good job in water maintenance and disinfection. The disinfection method is to sprinkle bleach on the water and let it take effect naturally.
