| Abstract |
A small number of experiments were made on phytoplankton cultures labelled with 14C; they confirmed earlier results obtained when using 32P. With female Calanus the volume filtered varied from about 1-40 ml per day, and the digestion of a diatom and two flagellates lay between 50 and 80 %. Since both carbon and phosphorus are important constituents of the algal cell, it is fair to assume that the major part of the organic material is digested. It may be concluded therefore that, during a period of diatom abundance in the sea, most of the food ingested is utilized. |
