What are the precautions for fish harvesting during freezing periods?

The Spring Festival is approaching, which is an important period for harvesting aquatic products. Brood fish and fish about to @#@136@#@ are raised together, so attention must be paid to protecting the brood fish from freezing. Do not carry out operations when freezing occurs. Add water to ensure a water depth of 1.5 m to 2 m to stabilize the temperature. Try to avoid exposing the brood fish to the air. Harvested brood fish should be bathed in 2% salt water for 15 minutes to 20 minutes to prevent and treat saprolegniasis. In places where eels are raised in net cages, the net cages should be promptly sunk to the bottom to contact the silt, and straw should be added on top of the cages for coverage, with operations reduced as much as possible to ensure safe overwintering.

For livestock and poultry, pig houses, cattle sheds and sheep pens should have windows closed to block wind and maintain the temperature of the pens. Appropriately increase the stocking density in the pens. Do not go out for grazing, and reduce the use of cold water for drinking as much as possible. Various viruses of livestock and poultry prefer cold and fear heat, so prevention and control of diseases such as highly pathogenic avian influenza, blue ear disease and foot-and-mouth disease must be effectively carried out.
