A large number of Korean oysters died, and the market gap was filled by increasing imports of Chinese aquatic products

South Korea's oyster fishing season in October has been impacted by high temperatures, leading to a significant die-off of oysters and heavy losses for farmers. The water temperature rise has also reduced the size of surviving oysters and increased the mortality rate of young oysters, with the aquaculture industry facing a crisis. High sea water temperatures have also caused the death of 49.23 million farmed fish, an increase of 55% over last year. In response, large South Korean supermarket chains have started importing Chinese mussels, abalones, and clams to make up for the shortage.

October is the peak season for oyster fishing in Tongyeong, South Korea, but this year's fishing season was overshadowed by the continued high temperature. Affected by the high temperature, the seawater temperature in Tongyeong and its surrounding areas has risen significantly, resulting in the death of a large number of oysters and heavy losses to farmers. At 7 a.m., the reporter followed Mr. Zhu, an oyster farmer in Tongyeong, to go fishing. At sea, fishermen salvaged the oysters hanging in the water one by one on board. However, what is worrying is that more than 50% of the oysters have died in the high temperature, and the size of the surviving oysters is far smaller than the normal standard, which does not meet the market sales requirements. Mr. Zhu said that although oysters themselves have a certain degree of heat resistance, from August to September, the water temperature exceeded 30 degrees Celsius for many consecutive days, the oxygen content in the water decreased, and ...
