Dinoflagellate cyst production in one-liter containers.

- Abstract
Methods for the production of dinoflagellate cysts in two types of 1 L containers have been developed. Using these methods, dinoflagellate cysts can be produced in amounts large enough for shellfish grazing experiments or whenever large amounts of cysts are needed. The species used were Scrippsiella lachrymosa (B-10) and toxic Alexandrium fundyense (CB501 and GTM25). Cultures of S. lachrymosa yielded 628 ± 74 cysts mL−1 and A. fundyense cultures yielded 350 ± 98 cysts mL−1. Findings suggest that aspects of the boundary layer between the media and the wall of the container are important for gamete mating; especially, the slope of the container wall appears to be relevant, which offers some explanation of previous observations that the shape of the container is important in the formation of dinoflagellate resting cysts. These observations may support the theory that physical interfaces in nature facilitate dinoflagellate encystment.
