Hong Kong Spring Festival market once sold a pair of 6000 Hong Kong dollars, which is a high-grade economic fish. China has also introduced it in recent years. Our county is rich in geothermal resources and has good conditions for artificial breeding and mass production of this variety. This paper briefly introduces the cultivation and management of the parent fish of Silurus japonicus.

The following is for your reference.

First, parent fish cultivation.

L, choose a swimming pool The parent fish culture pond should be an intensive culture pond with sufficient cold and hot water sources, no pollution, suitable water quality and convenient irrigation and drainage, with an area of 2-3 mu and a water depth of 2 meters.

2. Silk stockings. The stocking density should not be too high, and the water surface of parent fish should not exceed120kg per mu. Attention should be paid to cleaning the pond and disinfection before stocking, and the imported ones should be pure, neat, disease-free and healthy.

3. hello. Filamentous perch can be fed with wheat bran, bean cake, soybean and other feeds, preferably with formula pellet feed, and where conditions permit, it can also be fed with animal liver and silkworm chrysalis. Feed should be placed on a fixed bait table, and it is advisable to eat it every day, twice a day, so that rainy and low-temperature weather is reduced.

Second, aquaculture management.

1, keep warm. This species belongs to tropical fish, which has strict requirements on temperature, and the suitable water temperature is 22-32 degrees. When it rains or cold air comes, the water should be heated in time to raise the temperature. At ordinary times, the depth of the pool water should be kept, and attention should be paid to not rushing to raise the temperature, so as to avoid the adverse impact of sudden temperature change on the growth of parent fish. When the water temperature is too high, cold water should be replenished in time.

2. Stay hydrated. First, ensure that the water depth is more than 2 meters; The second is to ensure water sources. Ensure the timely and sufficient supply of hot and cold water; The third is to ensure the water quality, keep the water quality fat, lively, tender and cool, and the transparency is above 35 cm. Fresh water should be replenished frequently, generally 2-3 times a month, with water of 10-20cm each time. Drain the old water before adding water. In summer, the number of water changes and the amount of water can be appropriately increased. Each aquaculture pond should be equipped with an aerator for timely aeration or first aid. In winter, when the weather is fine, the heat preservation cover can be properly opened to facilitate air circulation and exchange.

Step 3 keep food. First, to ensure the nutrition of food, food should be fresh feed with high content of protein, and rotten and malnourished food should not be fed; Second, ensure the food intake. This variety has miscellaneous eating habits and a large food intake. Pay attention to feeding as needed; Third, ensure the hygiene of the dining table, often clean the dining table, remove the residual bait and sundries, and often hang baskets for disinfection.

4. Disease prevention. Prevention should be the main disease of Lateolabrax japonicus, and the specific preventive measures are as follows: (1) Keep the temperature of pool water above 20 degrees; (2) Disinfect the water regularly with quicklime10-15kg/mu (once a week) or use the bleaching powder solution of lppm; (3) Sulfonamides can be mixed with bait for feeding; (4) Adjust the water quality in time and often clean and disinfect the dining table. The common viruses of filament envy are Indian print disease, erythroderma and anchor crab disease, which can be cured by the right medicine. Generally speaking, filament jealousy will not appear on the premise of doing preventive work and raising correctly.

5. Prevention. First, remove weeds around the pool and beware of livestock entering the pool; Second, keep on duty all day during the winter, deal with hidden dangers in time, pay close attention to rainy and sultry weather, and pay close attention to diligent management; The third is theft prevention.
