Adult American Eel
American Eels inhabit all tributaries of Chesapeake Bay and can grow to 1.5 meters (5 feet) in length. They are catadromous, living the majority of their lives in freshwater and migrating to the ocean to spawn.
Adult American Eel
American Eels are nocturnal feeders that prey on insects, crustaceans, worms, fishes and mollusks.
Glass Stage American Eel
All American Eels spawn in the Sargasso Sea, with the larvae being transported to the east coast of North America by ocean currents. These larvae then metamorphose into glass eels and move into estuaries and rivers to continue their life cycle.
The gear used in this survey does not efficiently capture this species. Results should not be interpreted as a reliable index of abundance.
This index includes all American Eels >152 mm TL (total length) that are caught in the rivers during the months of April through September.
Data collected after the transition to a new vessel and net (June 2015) have been adjusted by a species-specific calibration factor. Note we were unable to calculate an index for 2020 in the Rappahannock and James rivers because of a pause in sampling due to COVID-19
