The toxicity of puffer fish is very high, and artificial culture can only weaken its toxicity. The puffer fish's body is cylindrical and has no ventral fins. After being stimulated, its chest and abdomen will expand like a ball. When artificially cultured, it needs to be maintained in a pond with good water quality, and the toxic parts must be removed when eating.

It just means that its toxin content is less than that of wild puffer fish. When eating it, boiling it in boiling water at 1 20 C1hour can destroy the toxin. You must eat puffer fish carefully. Tetrodotoxin mainly exists in gonad, liver, spleen, eyes, skin, blood and other parts of puffer fish. Its ovary and liver are highly toxic, followed by kidney, blood, eyes, gills and skin, and testis and meat are mostly weakly toxic or nontoxic.

Matters needing attention in cultivating puffer fish

After the puffer fish are put into the pond, there is a certain requirement for the water temperature. When the temperature is 15, the puffer fish still have a certain feeding ability, so it should be fed regularly. At the beginning of stocking, the puffer fish can form a habit of eating at a fixed point. The bait should be wet granular bait, and it is best to feed it now. The general feeding amount should reach half of the puffer fish's weight, at least twice a day.

When the water temperature drops below 12 degrees, the food intake of puffer fish will decrease obviously. When the water temperature reaches 10, the puffer fish will basically stop eating. At this time, it is necessary to stop feeding and increase the appropriate water temperature. When feeding, let the puffer fish eat well and get rid of the residual bait in time to prevent water pollution.
