"The scallop ran" "The scallop died" ... For years, shareholders have ridiculed listed company Zhangzidao with jokes. Nowadays, even in Japan, scallops are dying in large numbers.
According to media reports, a large-scale death of scallops has occurred in the Japanese market of Hokkaido Netgo recently, and about 180 million scallops have been confirmed to have died. Due to the large impact, the local water industry is even worried about the long-term impact on future production.
Widespread death of young scallops: Industry fears 'unprecedented'
Recently, Abashiri City Noto Lake reported a large number of deaths of young scallops, with a loss estimated at about 700 million yen.
Every year in September, farmers reportedly put scallop seedlings into baskets in Lake Nengqu and let them spend the winter in the water. However, since the end of March this year, farmers have found that a large number of young scallops have died in the baskets that can be left of the lake.
According to the Nishinetori Fisheries Cooperative, about 180 million dead grains have been identified so far, which is 90 percent of the fishery cooperative's planned production this year.

At present, the Abashiri City Fisheries Research Institute is investigating the quality of young scallops and lake water, but the cause of the mass death of scallops is unknown.
The vice president of the Scallop Committee of the Nishinetamori Fisheries Association said: "At present, the viability of some scallop species is weakening, and the impact is great. This is an unprecedented situation, so we cannot predict future trends. Another head of a fishing cooperative said: "Young scallops are still dying and it is not clear how far the losses will last." Similar damage has not been confirmed in the surrounding area, and young scallops cultured in Lake Nomachi account for about 6% of the total aquaculture in Hokkaido.
After the accident, Yoichi Mizutani, the mayor of Abashiri City, took the lead in setting up a countermeasure center at the Nishi Abashiri Fishery Cooperative to discuss how to support fishermen and deal with dead young scallops in the future.
Japan's scallop exports doubled, and the main consumer market was the Chinese market
According to data recently released by the Ministry of Agriculture, Forestry and Fisheries, the export value of agriculture, forestry and fishery products and food will increase by 14.3% year-on-year to 1,414.8 billion yen in 2022. The depreciation of the yen has helped Japan's agricultural and fishery exports set a record for 10 consecutive years.
The export of aquatic products increased significantly, of which the export of scallops was 127,800 tons, an increase of 10.5%. In markets such as China and Southeast Asia, "shellfish home cooking has become commonplace, and the use of shellfish in family meals is increasing," an export business official said. "At the same time, exports to the United States have increased due to the depreciation of the yen.
↑ Japanese fishermen save scallops
In Asia, the main consumers of Japanese scallops are Japanese restaurants and sushi restaurants. According to the analysis of the Agriculture, Forestry and Fisheries Market Development Division of the Japan External Trade Organization (JETRO), "During the epidemic, customers who visited Japan actively purchased Japanese scallops when they could not travel abroad, resulting in an increase in production. He is currently visiting Japan, the number of tourists is also returning to growth, and the Japanese related industries are looking forward to the market further development.
Is scallop death "natural disaster prevention"?
For fish farming, the large-scale destruction of scallops means very large losses. So can science and technology help people avoid such natural disasters? Judging from the statements of many researchers in the aquaculture industry, it seems that the occurrence of mussel death is difficult to prevent.
A local researcher in Zhangzidao in Dalian once told the media that marine livestock, like many agricultural products, often depend on the weather, and climate change has a great impact on farming. Extreme temperatures, reproductive capacity, lack of bait, and other factors can cause scallop death. "If there is a large degree of change or pollution in the environment, it will definitely affect agricultural production." Changes in climate, water quality and other factors may also gradually weaken marine life, but there will still be a certain lag and delay in mass death. "It's like when you have a problem, you don't die immediately, but at the end of the day, if you can't eat anything and you can't use the bottle, you're on the brink."
Can the large-scale destruction of Japanese netwash scallops be prevented in advance? Is there an additional impact on the management of the adjacent area? We also need to wait for the results of the investigation by the local office.
