Abstract The generation of reactive free radicals byChattonella antiqua (‘Red Tide’), which may be a causative factor in fish death, has been demonstrated by electron spin resonance spectroscopy and a microelectrode technique. Electrochemical detection indicates that superoxide anions are produced as a primary product, and undergo further reactions during diffusion in glycocalyx to produce hydrogen, hydroxy-, and carbon-centered radicals which are detected by ESR as secondary products. It is proposed that these reactive radicals are responsible for the destruction of the mucous membranes of fish on exposure to ‘Red Tide’.
