Feeding of the Estuarine Copepod Acartia Tonsa Dana: Carnivory VS. Herbivory in Natural Microplankton Assemblages
Abstract:Acartia tonsa was fed natural microplankton assemblages from Terrebonne Bay, Louisiana. In experiments done under three different environmental regimes, the ratios of microzooplankton carbon : phytoplankton carbon consumed were 0.69, 0.12, and 0.03 in August, September, and January when the ratios of micro zooplankton carbon: phytoplankton carbon available were 0.03, 0.02 and 0.004 respectively. Chlorophyll was cleared at low rates (<1 ml·copepod−1·h−1) in the three experiments, but because of its high standing stocks (> 17 µg·l−1) comprised a relatively large portion of the copepod's total carbon ingestion. Of the total carbon ingested, microzooplankton accounted for 41, 11, and 3% in August, September, and January.
