Description: 

The objective of the proposed research is to determine predation rates on Acartia tonsa nauplii and copepodites due to tentaculate larval Mnemiopsis ctenophores. These predators may be extremely important in controlling copepod population densities. This research examines predation not yet addressed in my ongoing research on the impacts of medusae and adult ctenophores on copepod populations. This research should complete examination of the major pelagic predators on Acartia copepods in the mesohaline region of Chesapeake Bay.
