The price difference between the price of "cod" in Qingdao City is ten times the big head fishy authenticity is misunderstood

The cod family is huge, and it is often heard of blue cod, silver cod, Alaskan cod, Icelandic cod, all kinds of dazzling. Recently, the research project "Key Technologies for Breeding and Breeding of Bare Lid Fish" participated in by the Yellow Sea Fisheries Research Institute passed the on-site acceptance. It is understood that the naked cover fish is a cold-water fish that grows on both sides of the Arctic Ocean and the North Pacific Ocean, also known as silver cod, which has high economic value. But in fact, from the biological classification point of view, silver cod belongs to the genus of bare-covered fish in the family Scorpiopodidae, and is not related to cod.

"Silver cod" is not cod

According to experts from the Yellow Sea Fisheries Research Institute, the project team introduced 60 bare-covered fish fry to carry out breeding and production in November 2013, breaking through the technology of wintering and summering, and its breeding and breeding technology research enriched the research content of low-temperature marine fish in China. Because of its resemblance to cod, the naked cover fish was first named "silver cod" by the Japanese market, but the price is much more expensive than the real cod, even more than the lobster.

The reporter learned from the interview that there are only three kinds of pure cod, Atlantic cod, Greenland cod and Pacific cod, all of which belong to the cod genus of cod in the fish family. Experts from the Yellow Sea Fisheries Research Institute told reporters that cod is a deep-sea cold-water fish, generally will not suffer from offshore pollution and other problems, and the living environment is very good. Atlantic cod is one of the world's largest annual catches, high economic value of the food fish, as a commercial fish species, its main export countries are Canada, Iceland, Norway and Russia, Japan is mainly produced in Hokkaido. Pacific cod is mainly produced in North Korea, South Korea, Japan, Russia and other countries. Due to the heavy fishing of humans, the populations of the three "true cod" species are in steep decline.

All called cod price difference ten times

Silver cod, Alaskan cod, Icelandic cod... The reporter visited the market and found that many markets have cod for sale, and there are many kinds of cod currently on the market, but the price difference is huge. The reporter saw in a supermarket on Tong'an Road that the cod sold by the supermarket is a block package, the packaging reads "deep sea cod", caught from the Bering Strait, imported from Russia, the price is only 15 yuan a catty. In another supermarket, frozen imported silver cod sells for as much as 160 yuan a catty. A supermarket sells "American Alaskan Wild Cod" for $59 per pound. The price difference between all kinds of cod is huge, from more than ten yuan a catty to more than a hundred yuan a catty, and the price difference is as much as ten times.

"If, strictly according to the biological classification, the real cod is the cod genus of the cod family Cod, then only three species of fish are real cod." Mr. Zhou, a wholesaler of imported aquatic products, told reporters that from the actual sales situation in the market, the silver cod, which is not a real cod, has become synonymous with high-grade cod, and it is also the highest-priced "cod" type.

Fake cod grabs real cod for the limelight

The reporter found that the cod sold in supermarkets and e-commerce today is mainly silver cod, Alaskan cod, etc., but these two types of cod are not "real cod". Among them, the silver cod, also known as black cod and blue cod, belongs to the genus of bare-covered fish in the family Blackfish of the order Scorpene, and the naked-covered fish is its real name. "Silver cod is now basically imported, and the market value is higher than that of real cod. Mr. Zhou told reporters that the flesh of the naked cover fish is more delicate than the cod, which is a regular product of high-end sushi restaurants and is also considered to be high-grade cod.

Alaskan cod comes from the genus Cod of the family Cod, also known as "Yellow Line Cod", also known as Mingtai fish, distributed in the east coast of the Korean Peninsula, the Sea of Japan and other waters, belonging to the near-bottom cold-water marine fish. Mintai fish is currently the second largest commercial fish in the world, most of which are made into minced meat and meat sauce, and most of the "cod meat cakes" and crab sticks that the public buys in supermarkets are yellow line narrow cod meat.

Big head fish is real cod

"In fact, the Pacific cod is what Qingdao locals say is the big head fish, this fish in the early years did not have a lot of love to eat, in recent years more and more on the market." Experts from the Yellow Sea Fisheries Research Institute told reporters that the scientific name of the big head is called Pacific Cod, which is a cold-water demersal fish that feeds on benthic small fish and shrimp. The main fishing grounds are in the northern Yellow Sea, east-southeast of Gaojiao, Shandong, and the southern and southeastern sea areas of Ocean Island. The fishing season is winter and summer, and the winter flood is from December to February of the following year. The summer flood is from April to July, and the production is the largest in winter. The staff of the Municipal Bureau of Oceanography and Fisheries told reporters that in recent years, the flood of large fishy fish in Qingdao's coastal waters has been obvious, and a large number of large fishy fishy fish have been ashore at major docks every winter, and the market price has been relatively low.

Yesterday, the reporter visited the Qingdao aquatic products market and found that the current market price is about 15 yuan per kilogram. "15 yuan is expensive, and when there are more fish in winter, it is less than 10 yuan a pound, which is cheap in fish." Mr. Yan, a seafood merchant at the Xiaogang Aquatic Products Wholesale Market, said. The public's evaluation of the big head fish is also mixed, "I didn't eat this fish before, and I feel that the big head fish is a low-grade fish." Mr. Wang, a citizen, said. However, many citizens believe that the fishy meat is tender and cheap.
