Why do all capelin have roe?
Capelin is a dioecious fish species that can also change from male to female and vice versa, and in which males are extremely rare, so almost all those eaten are female. When young, capelin is male; when grown, it becomes female. Only in this way can the mesh size be set at the time of fishing to release the small-bodied males and catch the females, and thus capelin remain in a state of "cradle-robber romance" throughout their lives. As for why every capelin in restaurants is pregnant, experts believe that "year-round spawning" is impossible, and that they should be caught intensively during the spawning season and then frozen in large quantities to ensure a year-round supply.
How much does capelin cost per jin?
The market price of capelin is about 6 to 10 yuan per jin. Capelin usually lives in the sea, and adult fish come to coastal estuaries to spawn in spring, with the spawning period from March to May each year. The hatching grounds are usually in larger river tributaries and shoals, which is also the best time for fishing. The eggs grow into adult fish after about 2 years, and in late autumn they swim up the river to spawn. Shishamo smelt can be caught in many areas along the northern coasts of the Pacific and Atlantic Oceans, and it is produced from the Heilongjiang River and the lower reaches of the Tumen River in northeast China all the way to the coastal waters of Taiwan, China.
