Abstract The marine filamentous bloom-forming cyanobacteria Trichodesmium thiebautii and T. erythraeum were collected at locations in the Carribean during Jan.–Feb. 1991. They were screened for toxicity using Artemia salina and several species of copepods, which were harpacticoid grazers, filter-feeding calanoids, or cyclopoid copepods. Approximately 50% of the 89 T. thiebautii samples caused〉 50% lethality of A. salina, though none of the 16 T. erythraeum samples caused〉 25% lethality. The T. thiebautii bloom samples were toxic to the calanoid and cyclopoid copepods and non-toxic to the harpacticoid grazers. In contrast the T. erythraeum bloom samples were not toxic to any copepods tested.
