The benefits of winter fish
The first is that winter temperatures and water temperatures are low, fish activity is weak, and their scales are tight. During fishing and stocking, fish mechanical damage can be reduced, and morbidity and mortality can be greatly reduced.
Second, the metabolism of fish bodies in winter is reduced. In the process of catching water and handling, fish species generally do not suffocate and death, thus improving the survival rate of fish species. The third is that the winter fish species can avoid the fish species and pond overwintering operations. The fourth is that the winter release of fish species will allow the fish species to be evacuated earlier and have a longer period of time to adapt to the new environment, so that the fish species can eat earlier, and accordingly extend the growth period, laying a foundation for the catching rotation and fish breeding. The foundation.
Winter fish should pay attention to four points
The first is to disinfect clear ponds before stocking. Excavate excess silt in the pond and repair the rod. After the ponds are well-trimmed, 75 kg of lime are used to disinfect the ponds per acre, and then the base fertilizers are applied and watered. After 10-15 days, the fish species can be released. The second is that in front of Xiatang, 10 grams of bleaching powder, 8 grams of copper sulfate, and 20-30 minutes of immersion in each cubic meter of water can greatly reduce the occurrence of fish disease. Third, fish stocking must be carried out on a sunny day, avoiding rain, snow and cold weather. Fourth, after the stocking of fish species, it is necessary to strengthen feeding and management.
