Barracuda crab harvest price is low Qingdao citizens eat a big fish is not easy

Original title: This year's pike crab and harvest prices are lower citizens enjoy the blessing of the expert: large fish resources recovery slow small seafood singing the protagonist

The sea has been closed for nearly four months, and the Yellow Sea is fishing today. In the nearly four months of the fishing moratorium, the aquaculture and frozen products have been fought together, and they have not owed the blessings of the citizens, especially after the opening of the East China Sea on August 1, the "pike crab" army went north and quickly occupied the island city market. Since August, the seafood market has basically become the "world" of pike crabs, and the fresh pike crabs have beautiful meat and low prices. Judging from the production of the southern seas, this year is the "big year" of the pike crab harvest, while at the same time, after the opening of the sea, other seafood, especially large fish, is rare. "In recent years, after opening the sea, small fish and shrimp are the mainstays, and there are fewer and fewer big fish." Nanjiang Wharf fisherman Lao Qu said.

Market: Southern pike crab "rampant"

Yesterday, at a farmer's market in Laoshan District, a farmer surnamed Chen introduced: "Before August 1, I mainly sold fish and shrimp, and recently expanded the operation of barracuda crab. "These two days at his stall, except for the perch in the leftmost pool, the rest of the area is full of pike crabs. The stall owner admits that with the large number of pike crabs on the market, the price is getting lower and lower. "You see such a big crab is only 25 yuan / catty, cheaper than last year." Mr. Chen told reporters that recently he has to sell seventy or eighty kilograms of barracuda crabs a day, "most of the fish are still farmed fish in the south, like sea bass, blackhead fish, wild sea catch very little, not to mention the big ones."

"Two days ago, friends came from Beijing and invited them to eat crabs for two days in a row, and although crabs are not the fattest time, they are cheap and enjoyable." Ms. Zhu, a citizen who lives in Laoshan, said. Since August, Nanshan Market has become the main battlefield of southern pike crabs in the island city, and at least 100,000 kilograms of pike crabs are sorted and sent here every morning for transportation to Qingdao's major farmers' markets and supermarkets. It is reported that some of these pike crabs come from Lianyungang, Jiangsu Province, and some come from Zhoushan, Zhejiang and other places. Mr. Wang, a seafood wholesaler, told reporters that this year's southern pike crab harvest is a big fat compared with last year, and the price has also dropped. The staff of the Municipal Bureau of Oceanography and Fisheries told reporters that after the opening of the sea on September 1, Qingdao's local pike crabs will also enter the market, and around the Mid-Autumn Festival is the fattest time for pike crabs, and the citizens can feast on them.

From September 1, the fishermen who are ready to go to sea are still full of expectations for the upcoming opening of the sea: "Finally can go to sea, from the situation in previous years, generally still small fish and shrimp mainly, but fresh, everyone is still good this bite." Fisherman Lao Qu said.

Experts: Two major reasons for the bumper crab harvest

In recent years, pike crabs have been harvested year after year along China's coast, but the recovery of fishery resources such as large fish has yet to be observed. Cui Zhaoxia, an expert at the Institute of Oceanography of the Chinese Academy of Sciences, believes that there are two main reasons for the bumper harvest of barracuda crabs along the coast of China. From an ecological point of view, as the sea temperature gradually increases, the total amount of plankton and plants in the ocean declines, "the phytoplankton in the sea is the bait for fish and pike crabs, and the pike crab is at the top of the food chain in the ocean." This means that more and more pike crabs will "compete" with large fish upstream in the same food chain, and the less food they have, the less conducive it is to the survival of large fish. In addition, from the perspective of human factors, in the past few years, the major coastal provinces and cities have increased the breeding and stocking of pike crabs, and the huge increase brought about by the release into the sea before the start of the annual fishing moratorium is also one of the reasons for the bumper harvest of coastal pike crabs.

Big fish eat small fish, small fish eat shrimp, which is the law of fishing grounds for thousands of years. In Lao Qu's view, the pike crab has been harvesting for many years and "running rampant" in the sea, which indicates that "shrimp soldier crabs will be called kings", and it is difficult to see changes in the situation of fewer fish along the coast in the short term.

Crabs and small fish and shrimp become the protagonists of the sea

Fishery experts told reporters that striped fish, yellow croaker, silver pomfret, semi-slippery tongue fish, Chinese shrimp, etc. are all high-quality resources that were common in the Yellow Bohai Sea 20 years ago, but from the current research, the traditional resources such as giant yellow croaker and wild Chinese shrimp are on the verge of exhaustion, and the resources of various traditional high-quality marine species such as Chinese shrimp have declined significantly, and it is difficult to form a fishing flood.

From the perspective of the population structure of fishery resources, small pelagic fish, cephalopods, small shrimp and crabs with short life cycles and low trophic levels have gradually replaced the original large-scale high-quality economic species. According to a large number of research data from the Yellow Sea Fisheries Research Institute, the Yellow Bohai Sea, which was once known as the "cradle of fishery" and "natural fish barn", was a high-quality fish species in the 1960s as striped fish and small yellow croakers. In the 1980s, it was dominated by yellow crucian carp, spiny plumtail and kong ray. In the early 1990s, it was dominated by anchovies, red-nosed mackerel and spotted crayfish, and now it is dominated by goby. The waters of the Yellow Sea are now dominated by fine-striped lionfish and sturgeon, and there is still a certain production of small yellow croaker and mackerel, but it is far less than that of that year. The marine living resources in China's coastal waters have been in serious decline, fishing targets have been frequently replaced, and the decline rate of high trophic level trophic level is higher than that of the global level. To use the most popular words, most of the high-quality fish in the Yellow Bohai Sea in the 1960s were large-scale high-grade fish at the top of the food chain, but with the increase in fishing intensity, the high-quality main fish in the Yellow Bohai Sea gradually moved down the food chain level, and now it seems that there are more small fish and shrimp left.
