In winter, fish that have survived in natural environments typically stop feeding, while those raised in greenhouses require more careful management. Here are the three key aspects of fish farming during the cold season:
1. Enhance greenhouse fish care. Currently, the main species being farmed include tilapia, bearded seabream, and freshwater whitefish. When raising tilapia, maintaining stable water temperature and managing water quality are crucial to avoid damage from frostbite, especially on the head. Regular disinfection using chlorine dioxide is recommended, and high-protein, balanced feed pellets should be used as much as possible. Bearded seabream are relatively easier to raise, making water quality control more manageable. Chlorine dioxide is also commonly used for water sterilization, but special attention must be given to preventing skin diseases. When feeding animal by-products like chicken intestines, it's important to ensure the feed is fresh and of good quality. The basic principles for raising freshwater whitefish and tilapia are similar, but there are two key differences: first, the use of organic phosphorus drugs is strictly prohibited; second, vitamin supplementation is necessary for freshwater whitefish, and some fresh vegetation can be offered in the corners of the pond.
2. Monitor market prices. Many agricultural products are gradually returning to reasonable levels, but the price of freshwater fish remains low. This is mainly due to market supply and demand dynamics. However, with the recovery of prices for other livestock and poultry products, and with the approach of the New Year, the price of commercial fish is expected to rise. Farmers with sufficient financial resources may not need to rush to sell their fish immediately.
3. Focus on fingerling management. Due to the low winter temperatures, pathogenic bacteria are less active, and fish scales remain tight, making winter an ideal time for raising fingerlings. However, because of the cold water temperature, if fish get injured, they are highly susceptible to bacterial infections (note that malachite green is a banned substance). Adding salt to the water can help prevent such issues. Moreover, scientific research has shown that when grass carp are vaccinated and inoculated together, it significantly reduces the risk of future outbreaks of grass carp disease.
By following these strategies, fish farmers can better manage their operations during the winter months and prepare for a more profitable spring season.
