Nutrient budget and production during a red tide of Gymnodinium catenatum in Ria de Vigo, NW of Spain

AbstractAs the production cycle in the rías during red tides of migrating organisms developes through three levels (carbohydrates production, uptake of nutrients and remineralization), a three layered box was used to calculate the production of Gymnodinium catenatum in this three levels during a red tide occurred in October 1986 in the Ría de Vigo. The vertical migration of Gymnodinium catenatum showed differential synthesis of cellular compounds. The production of carbohydrates takes place in the first leve1 while the uptake of nutrients occurs in the second one, using these carbohydrates as energy source. Therefore a vertical transport of nutrients is produced by G. catenatum. By using this box model we can distinguish between the production carried out by this organisms endowed with vertical migration and the usual one following a Redfield ratio
