South Korea: Research on amberjack farming in response to high temperatures begins in earnest

Gyeongnam Provincial Fisheries Resources Research Institute announced on the 11th that it has secured 500 amberjack midges, a large-sized aquaculture species to cope with high temperatures, and has begun aquaculture research in earnest. According to the National Institute of Fisheries Science, over the past 55 years (1968-2022), the average annual surface water temperature in Korean waters has increased by 1.36℃ by 0.025℃ per year, exceeding the world average of 0.52℃. This means that Korea's average annual surface water temperature rise rate is more than 2.5 times higher than the global average, which is believed to have been the main cause of this year's mass mortality of farmed fish. Amberjack is a cultured fish species suitable for high-temperature farming as its optimal growth water temperature is between 20 and 31 degrees Celsius, and it is distributed throughout tropical and temperate waters of the entire ocean, including Korea. While bluefin tuna is the largest fish in the ...
