Migration story
Sargasso Sea
American eels (Anguilla rostrata) likely hatch here Larvae move north on Gulf Stream currents Glass eels arrive in estuaries Eels grow for many years in rivers and streams Adult silver eels return to the Sargasso to spawn
Why do we care? Eel numbers are going down
The population of American eels is declining. What factors could be causing this?
Historic order of impact:
(adapted from John Casselman, Queens University)
1,000,000+ eels caught & released above barriers since 2008 ~1,000 volunteers annually How are people helping to better understand eels? The Hudson River Eel Project
Fyke nets are set in tributaries of the Hudson. Each day in the spring volunteers and students check the nets, count the eels, record the data, and release the eels above the next barrier to migration.
