South Korea: Request for management of ‘abalone cage farming’ during the rising water temperature

Published Mar 31, 2023

Tridge summary

The Ministry of Maritime Affairs and Fisheries and the National Institute of Fisheries Science in South Korea are advising farmers who manage abalone cage farms to prepare for the anticipated rise in spring temperatures. The Korea Meteorological Administration forecasts that this year's spring temperature will likely be higher than normal, leading to a faster increase in water temperature. This could advance the abalone breeding season, necessitating earlier breeding density control. The institutions suggest limiting the number of 3-year-old abalone to 1,100 and reducing food by half when the water temperature reaches around 24℃. The rise in water temperature could also reduce the seaweed and kelp harvest, a crucial food source for abalone, by about two weeks.

[Reporter Lee Jin-woo of The Korean Rural Newspaper] Higher temperatures expected in spring Advancement of breeding density control work Reduce food intake according to water temperature The Ministry of Maritime Affairs and Fisheries and the National Institute of Fisheries Science are urging people to make every effort to manage abalone cage farms ahead of the rising water temperature in spring. This is because, in the three-month long-term forecast announced by the Korea Meteorological Administration at the end of March, the probability that the spring temperature this year will be similar to or higher than normal is expected to be more than 50%. According to the Korea Hydrographic Institute, as the low-temperature period ends, the water temperature tends to rise rapidly along with the temperature rise, showing a distribution of water temperature that is 0.8 to 2.3 ° C higher than the previous year. The time when the water temperature reaches 15℃ is predicted to be around ...
