Gao Qing Fishery Technician Delivers Ice-Cooling Technology

In order to reduce the damage caused by snowstorms to fishery production and avoid the phenomenon of overturning ponds due to water and oxygen deficiency at the time of spring snowmelting, the Gaoqing Fisheries Bureau took active actions to scientifically instruct farmers to implement aeration in aquaculture ponds and ensure the winter fishery. Safe Production. The first is the implementation of perforated chemical oxygenation for thicker aquaculture ponds. The purchase of over-supply oxygenated tablets for fisheries with sodium carbonate will be distributed free of charge to farmers, and aquatic experts will be invited to guide the application methods on site to ensure the safety of the use of drugs and increase the oxygenation effect. The second is to carry out physical ice-breaking and oxygen supplementation on aquaculture ponds with large areas and thin ice layers. A special working team composed of fishery technicians and business leaders was set up to provide in-depth knowledge of the situation on the ground and to ensure that there were no deep-freezing damages. The farmers were orderly organized to break ice and supplement their operations, and the ice cubes and other miscellaneous debris were promptly removed. The object is to increase the exchange rate of water bodies and properly increase the water level of the pond to achieve the purpose of supplementing oxygen and oxygen and stabilizing the water temperature.
