The pufferfish is a river fish, and the pufferfish was formerly known as pufferfish.

The pufferfish is a collective name for the fish of the family Pufferidae of the order Scleractinia, commonly known as pufferfish. Since ancient times, the puffer fish eaten in China have been found in rivers, and have been named "puffer fish" because of the chirping sound they make when they are caught out of the water, which is similar to the sound of a pig's squeal.

The river dolphin is a warm temperate and tropical offshore demersal fish that inhabits the middle and lower layers of the ocean, and a few species enter freshwater rivers and make their entire body float to the surface in the shape of a ball when they encounter external dangers, while the small spines on their skin stand up to defend themselves.

Toxins in pufferfish:

The reproductive glands

are the ovaries and spermathecae. The ovaries are highly toxic, and are one of the most highly toxic parts of the pufferfish. The spermathecae are slightly toxic or non-toxic; the ovaries and spermathecae are oblong in shape and are located in the posterior part of the abdominal cavity, near the anus.

The two are easy to distinguish in the reproductive period, the testes are milky white and the ovaries are light yellow; in cross-section, the ovaries are in the form of white milky rice, while the ovaries are in the form of granules; however, after the fall when the reproductive period has expired, the ovaries and spermathecae are both atrophied, and it is more difficult to distinguish the two from each other.

The liver

is a large longitudinal organ located on the right side of the abdominal cavity, connected to the enlarged stomach, the lower tip of which reaches near the anus, and is grayish-brown in color, with a green gallbladder on the inner side. The liver is a very poisonous part of the river herring, so it is important to pay special attention to the river herring and make sure that it is dissected cleanly before eating, and the artificially cultivated herring can be eaten by frying in oil.

Skin and blood

The amount of toxicity in the skin varies depending on the species of puffer, but the skin of the puffer contains little or no toxicity. The blood, especially the two so-called spinal blood clots, or spleens, are highly toxic.

Intestines

The stomach is so large that it can inhale water or air to make it expand, and under the stomach is the intestines, which reach the anus by making two folds in the abdominal cavity. The stomach and the intestines are also poisonous, but the toxicity is much smaller than that of the ovaries and the liver.

Muscle

Muscle can be regarded as non-toxic, so as long as you dig out the guts of the puffer, and then peel off the skin, clean, is not toxic. However, when a river herring is dead for a long time, the toxins in its internal organs are dissolved in its body fluids and can seep into its muscles over time, so it is important to be on guard. Especially the production of fish fillets (fish sashimi), with 2% to 5% lye immersion, more secure.
