Organism responsible for paralytic shellfish poisoning could affect fisheries

New research published in Scientific Reports by scientists at the University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology suggests that ingestion of the toxic dinoflagellate Alexandrium fundyense changes the energy balance and reproductive potential of a particular copepod, a small crustacean, in the North Atlantic that is key food source for young fishes, including many commercially important species. Alexandrium fundyense is a photosynthetic …
