The Relation between the Red Tide Occurrence and the Sea Water Temperature in South Sea of Korea

Abstract

Red tide blooming causes the serious fisheries damages. This study investigated the relation between the characteristics of red tide occurrence and the sea water temperature. The red tide occurrence data from National Institute of Fisheries Science(NIFS) and sea water temperature data from the Korea Hydrographic and Oceanographic Agency. In Tongyeong, the most of red tide occurred in August. The highest number of red tide occurrence was in 2014. Cochlodinium polykrikoides concentration more than 1000 cells/ml in 2013 was 29 times in August. For the red tide occurrence, the best sea water temperature is between 22 and 25℃ which starts from the end of June to the beginning of the July and the red tide is expected to occur about after one month. It would be concluded more accurate results by using the satellite climate data for the further study.
