A Case for Accelerated Reestablishment of American Eel in the Lake Ontario and Champlain Watersheds
ABSTRACT The catadromous, panmictic American Eel ( Anguilla rostrata ) historically comprised nearly 25% of fish biomass in Atlantic coastal streams, supporting sizeable fisheries for centuries. However, the population has collapsed in its primary range. It is now proposed or listed as “endangered”...
