Cold-water fish refer to fish that live in water temperatures below 20 degrees. These fish cannot survive in water temperatures above 20 degrees. China is one of the countries with the most cold-water fish varieties, the widest distribution and the richest resources. Common cold-water fish include pike perch, stonefish , sturgeon , rainbow trout, etc. Let’s talk about the cold-water fish farming techniques. 1. Breeding environment Cold-water fish farming has high requirements for water quality. The water must be clear and free of pollution sources. The water should also have sufficient dissolved oxygen and suitable temperature. During the breeding process, water quality should be tested regularly to ensure that the water meets the breeding requirements. 2. Stocking density Stocking density is affected by many factors, such as variety, size, water quality, etc. When determining the stocking density, comprehensive consideration should be given to the actual situation to ensure that the fish have sufficient growth space and resources. 3. Feeding Choose feed that is nutritionally complete and of reliable quality, and feed it appropriately according to the feeding amount specified in the feed instructions. During the feeding process, the growth and appetite of the fish should be observed regularly, and the feeding amount should be adjusted in time. 4. Daily management This includes regularly testing water quality, observing the growth, activity and appetite of fish, identifying problems in a timely manner and taking measures. Keep the water clean and at a suitable temperature, and pay attention to preventing the occurrence of fish diseases. 5. Site selection and pool construction You should choose an area that is far away from pollution sources, has a quiet environment and good water quality. When constructing aquaculture ponds, they should be reasonably designed according to the aquaculture species and scale, and the water supply and drainage facilities should be reasonably planned to ensure smooth water flow. 6. Variety selection Based on comprehensive consideration of local market demand, climate conditions and breeding conditions, select varieties with fast growth, excellent quality and strong disease resistance. 7. Water quality management Test water quality regularly to ensure that it meets aquaculture requirements. Carry out water exchange, oxygenation and other measures according to actual conditions to keep the water clean and at a suitable temperature. 8. Feed selection Choose feed that is nutritionally complete and of reliable quality, and feed it appropriately according to the feeding amount specified in the feed instructions. Pay attention to the growth and appetite of the fish, and adjust the feeding amount in time. 9. Disease prevention and treatment Regularly observe the growth, activity and appetite of the fish, identify problems in time and take measures. Regularly disinfect fish and test for pathogens to prevent the occurrence of diseases. By mastering these breeding techniques and precautions, the growth rate and quality of cold-water fish can be effectively improved, while reducing the occurrence of diseases and improving breeding efficiency.
