Korean coastal waters have experienced a significant increase in the frequency, severity and duration of harmful algal bloonn (HAB) events, which can cause large economic losses in the aquaculture and fishery industries and have major environmental and human health impacts. HABs associated with the planktonic dinoflagellate, Cochlodinium polykrikoides, have been known to be responsible for massive fish kills during the summer and fall seasons in Korean coastalwaters. These "red tides" occur in the surface waters to an approximate depth of 3 meters and affect the economies of local coastal communities by causing fish mortalities.
