Abstract
Red tides in the Golfo de Nicoya, Costa Rica, are caused by Cochlotinium catenatum Okamura. The maximum concentration of cells was 80x106 /L. Four-celled colonies dominate in natural samples, while in culture, unicells and pairs are more common. Measurements of primary productivity were impractical because of cell autolysis. Environmental conditions controlling initiation and termination of blooms are unknown. The red tide is apparently non-toxic.References
