Pufferfish can bite people. The teeth and jaws of pufferfish are very hard and can crush extremely hard shells.

Tetrodotoxin is mainly found in the gonads, liver, spleen, eyes, skin, blood and other parts of pufferfish. The ovaries and liver are highly toxic, followed by the kidneys, blood, eyes, gills and skin, testes and meat. Most are weakly toxic or non-toxic. When handling pufferfish, you must strictly and carefully remove the pufferfish's internal organs and eyes, remove the gills, peel off the skin, remove the tendons and blood, and wash repeatedly with clean water.

Precautions for feeding puffer fish

It should be noted that puffer fish overwinter at a high density indoors and are prone to diseases. Before entering the pond, fish species should undergo medicinal baths to remove surface parasites and prevent injured individuals from being infected with bacteria or saprolegnia. During the overwintering period, prevention should be the main focus. Generally, antibiotics are used to disinfect the body surface every 10 to 15 days. You can also continuously feed antibiotic-containing bait for 3 days every 15 to 20 days to disinfect the body. . Sick fish should be fished out promptly and isolated for treatment to prevent the spread of fish diseases.

During the overwintering process of puffer fish, you should always pay attention to changes in water temperature and weather forecasts, and be fully prepared before the cold wave comes to ensure that the heating equipment can operate in time. When the indoor water temperature is lower than 12°C, heating measures should be taken to increase the water temperature to about 14°C and keep it constant.
