Matters needing attention in raising puffer fish

It should be noted that puffer fish has a high indoor wintering density and is prone to disease. Before the fry enter the pond, they should take a medicinal bath to remove parasites on the body surface and prevent the injured individuals from being infected with bacteria or water mold. During the winter, prevention is the main thing. Generally, the body surface is disinfected with antibiotics every 10 ~ 15 days, or the bait containing antibiotics is continuously fed every 15 ~ 20 days for disinfection in vivo. Ill fish should be fished out in time and treated in isolation to prevent the spread of fish diseases.

During the wintering process of puffer fish, 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 increase the water temperature to about 14℃ and keep it constant.
