Grazing by 35 to 202 μm micro-zooplankton in Long Island Sound

  • G. M. Capriulo
  • E. J. Carpenter


Micro-zooplankton abundance in Long Island Sound varied from 103 to 104 animals l-1 at the station studied and consisted almost entirely of tintinnids. The micro-zooplankton were found to sometimes remove a significant portion of the chlorophyll a standing stock, with an upper limit of 41% of the standing stock being ingested per day. Observed ingestion rates ranged from 0.001 to 0.17 ng chlorophyll a removed animal-1 h-1 and from 0.06 to 87 cells removed animal-1 h-1, depending on season and type of cell being ingested. Filtering rates varied from 1.03 to 84.7 μl animal-1 h-1. As a community, the micro-zooplankton exhibited the same order of magnitude ingestion and filtering rates as those noted for copepods.
