Farming techniques for black fish.
The blackfish, also known as snakehead, is a common freshwater fish. Due to its tender meat and delicious taste, black fish is loved by consumers. In order to meet the market demand, many farmers have started to try to farm black fish. The following will introduce the farming technology of black fish to help farmers better breed black fish.
First, the breeding environment.
Choosing a good breeding environment is the key to the success of black fish farming. Blackfish are adaptable and can be farmed in a variety of waters, but in order to obtain better yield and quality, it is necessary to choose a place with sufficient water sources, good water quality, and convenient transportation for farming. Before farming, the pond needs to be cleaned and disinfected, which can be disinfected by splashing disinfectants such as quicklime or bleaching powder.
2. Fingerling selection and stocking.
Choosing healthy, high-quality fingerlings is one of the keys to success in farming blackfish. When choosing fish fingerlings, you should choose fish species with neat size, bright body color, and no disease or injury. The stocking density should be determined according to the pond conditions, water quality conditions, feed types and other factors, and generally 1000-3000 black fish can be stocked per mu. Fingerlings need to be disinfected at the time of stocking, which can be soaked in salt water or potassium permanganate solution.
3. Feed feeding.
Blackfish are carnivorous fish and need to be fed animal feed, such as small fish and shrimp, insect larvae, earthworms, etc. When feeding, we should pay attention to the quality and quantity of feed, and ensure that the feed is fresh, free of spoilage, and comprehensive nutrition. The amount of feeding should be determined according to the growth stage and feeding habits of the black fish, generally feeding 1-2 times a day, and the feeding amount accounts for 5%-8% of the body weight of the black fish. When feeding, you can use fixed-point feeding or scattered feeding, and choose according to the actual situation.
4. Water quality management.
Water quality management is one of the important aspects of farming blackfish. In the process of breeding, it is necessary to regularly fill with new water and replace the water body to maintain the freshness of the water quality and the appropriate pH value. At the same time, it is necessary to regularly use quicklime or microbial agents to regulate water quality and maintain water stability and ecological balance.
5. Daily management.
Day-to-day management is an essential part of the daily work of farming blackfish. It is necessary to regularly inspect the pond to observe the growth, feeding and activity of the black fish, and find and deal with the problems in time. At the same time, it is also necessary to do a good job in the cleaning and sanitation of the pond, and promptly remove the residual bait, dead fish and other wastes, so as to keep the pond hygienic and tidy.
6. Disease prevention and control.
Disease prevention and control is one of the important aspects of black fish farming. In the process of breeding, antibacterial drugs, insecticides and other diseases should be used regularly to prevent the occurrence of diseases. Once a diseased fish is found, it should be isolated in time to prevent the spread and spread of the disease. At the same time, it is also necessary to strengthen daily management and improve the disease resistance of black fish.
In short, the culture technology of black fish needs to start from many aspects, including breeding environment, fish species selection and stocking, feed feeding, water quality management, daily management and disease prevention. Only by mastering these technical points can we better breed black fish, improve production and quality, and obtain better economic and social benefits.
