Reevaluation of the Generation of Reactive Oxygen Species (ROS) by Cochlodinium polykrikoides as a Fish Killing Factor; Comparison with Chattonellla marina

Cochlodinium polykrikoides is one of the most harmful red tide dinoflagellates and is highly toxic to fish. Red tides due to this dinoflagellate have been reported in Korea, Japan, and other countries, and frequently cause severe damage to fish farming. Recently study has suggested that C. polykrikoides generates reactive oxygen species (ROS) such as superoxide anion ($O_{2-}$) and hydrogen peroxide ($H_2O_2$), and the ROS-mediated ichthyotoxicity has been proposed.
