Precautions for eating puffer fish

It should be noted that puffer fish have a high indoor wintering density and are prone to diseases. Before the fingerlings enter the pond, they should take a medicated bath to remove parasites on the body surface and prevent the injured individuals from being infected with bacteria or water mold. During the wintering period, prevention should be given priority. Generally, the body surface should be disinfected with antibiotics every10 ~15 days, or the bait containing antibiotics can be continuously fed every15 ~ 20 days for 3 days to disinfect the body. The sick fish should be fished out in time and treated in isolation to prevent the spread of fish diseases.

In the process of puffer fish overwintering, we should always pay attention to the change of water temperature and weather forecast, and make full preparations before the cold wave comes to ensure that the heating equipment can operate in time. When the indoor water temperature is lower than 12℃, measures should be taken to raise the water temperature to about 14℃ and keep it constant.
