The fish is miscellaneous, and the seedlings feed on planktonic plants and animals. Adult fish recipes are widely used. All kinds of aquatic young animals, organic debris, and insects eat, and they also eat small fish, shrimp, and crabs and shellfish. Under artificial breeding conditions, can eat complex feed. The sexual maturity is late, and the breeding season is from February to October each year. There is a variety of forms such as pond single breeding, polyculture, and cage culture.
1. Fish pond conditions: You can enter and drain a convenient pond. The previous water level is 100-150 cm. The late 150-250 centimeters requires ventilation and sunny weather.
2. Stocking densities: Adopt high-density farming methods to store 10-25 fishes per cubic meter. 1000-1500 acres are put in ponds and 100-200 tails/cubic meters in cages.
3. Feeding and Feeding: Freshly-fed fish fry mainly feed on planktonic plants and animals. Therefore, it is necessary to use fertilizers in underwater pools, but also to soak milk and feed egg yolks. After a few days, juveniles can ingest small-grained artificial compound feeds and feed them twice a day. They are fed at 9:30-10:00 a.m. and 4:00-5:00 a.m., each time. For 80% full, the amount of feed should be uniform and avoid intermittent food. The feed protein content should be around 40%.
4. Water quality management: (1) Adjustment of water color: In the spring, the pool water should be fat, and the transparency should be controlled between 25-30 cm. In summer and autumn, due to the high water temperature, the feeding activities of fish are also vigorous. There are also more metabolites and residual baits in the pool water. The transparency of the water body should be controlled within 30-40 cm in accordance with the principle of “less amount of diligenceâ€. (2) When the temperature is low in spring, the pond is filled with shallow water, which is conducive to raising the water temperature and breeding natural organisms. In summer, it is added to the highest water level so that the lower water temperature is not too high. If you refer to a stream with a low water temperature or a spring to raise the fish, pass it through a period of time before injecting it into the pond, or store it in a storage tank for a certain period of time to increase the temperature of the water. In areas with large winds, it is possible to plant jungle wind shields near the ponds to keep the ponds at a certain temperature. (3) Increasing dissolved oxygen in water: Injecting new water or changing water into the fish pond is a method to increase dissolved oxygen, where aerators should be used to improve yield. (4) Adjustment of PH value: Quickly applying quicklime to the fish pond can effectively adjust the pH of the water. Generally used once every 20 days or so, the high temperature season can be shortened to about 15 days. The amount of quicklime is 15-25kg per mu. After the water is dissolved, the residue is removed and the upper layer of lime slurry is splashed. In the breeding process of Baisuigong, as long as the management of the water quality in the culture ponds is strengthened, almost no disease will occur.
Baishuigong is a sub-alkali salt fish, originating from Malaysia, Myanmar, Indonesia and other Southeast Asian regions. It has strong adaptability, easy breeding, wide living habits, strong disease resistance, firm and fresh flesh, and no earthy smell. child. The fish is long side flat, flat head, short kiss. It can grow up to 65 centimeters in length and the heaviest can reach 5 kilograms. Its normal life temperature is 22-30 degrees Celsius. The optimum temperature is 22-25 degrees Celsius, the lower temperature limit is 12-16 degrees Celsius, and it begins to die when the water temperature is lower than 12 degrees Celsius. Adapt to PH value between 7.0-8.2.
