Appearance features: 80- 100cm long, oval. The back is smooth, the dorsal fin moves back to the tail handle, which is symmetrical with the gluteal fin up and down, the pectoral fin is wide, the head is big, the eyes are close to the top of the head, and the center of the body is cylindrical. The whole body is yellow-green, with dark black spots on the back and silvery white abdomen.
At present, the annual output of fugu orientalis has a downward trend. China was rich in resources in the 1950s and 1960s. After the mid-1960s, due to the increasing demand of Japan, fishing in the Yellow Sea and the East China Sea increased greatly, and South Korea also strengthened its fishing intensity. In 1974, the annual output of Japan/KLOC-0 in the Yellow Sea and the East China Sea was as high as 10,000 tons, and in recent years it was about 2,000 tons.
Living habits Warm-water rare bottom fish in coastal waters and estuaries.
Reproductive habits of fugu orientalis mature early, and the number of eggs increases with the growth of fish, with more than 2 million large individuals; The spawning population of small and medium-sized species is 90-230mm long, with150-180mm dominant, weighing 45-420g, and the fecundity is13-290,000 eggs. All species belong to one ovulation type. The incubation time of eggs is long, which takes 150-225 days. It lays sticky eggs, which are ovoid and oily balls. The egg diameter varies from 0.25 (Dongfangtun)-1.5 (Dongfangtun) mm according to different species. There are a wide range of feeding categories, mainly feeding on benthos. The food is cuttlefish and clams in mollusks, shrimps, crabs and shrimps in arthropods, nereis in annelids, sea urchins and shrimp tails in echinoderms, and many small fish, such as sea bream, octopus, goby and so on. The fishes of the genus fugu are fierce by nature.
Endangered grade is precious
Protection measures In order to make rational use of resources, we have discussed with Japan and South Korea the breeding protection plan. Initially, during the breeding period, several kinds of fugu rubripes and fugu pseudobulbifera with high economic value will be banned for a short period of time, and fixed fishing can be carried out at other times. Since the 1970s, the artificial proliferation of fugu rubripes in Japan has been successful, and the annual output is expected to reach about 10,000 tons if appropriate measures are taken within three to five years.
