Ingestion rates were obtained by incubating aliquots of net-collected mesozooplankton with natural seawater. The results showed a weak pressure of mesozooplankton on algae and protozoans, with grazing impacts on community stocks averaging 1.3, 1.4 and 1.5 % for phytoplankton, ciliates and dinoflagellates, respectively. Chlorophyll a (chl a) >5 μm was grazed at higher rates than chl a <5 μm, and in some stations dinoflagellates were preferred over ciliates. In general, ingestion rates were low, yielding to daily rations ranging from 2 to 20 % of body carbon, which were too low to cover the metabolic demand of mesozooplankton in most of the stations. We hypothesize that this unexpected result could be in relation to the presence of the toxic dinoflagellate Gymnodinium catenatum in the study areaPeer ReviewedInter ResearchConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2019201920022019info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/180993reponame:DIGITAL.CSIC.
