Nutritional suitability of the dinoflagellate Ceratium furcoides for four copepod species
The nutritional suitability of Ceratium furcoides for Eudiaplomus gracilis, Mesocyclops leuckarti, Thermocyclops oithonoides and Cyclops abyssorum was studied by observing ingestion and assimilation. The dinoflagellate was ingested by female adults of all species. The calanoid copepod E.gracilis cou...
