Abstract
Local movements of 16 radio-tagged American eels (Anguilla rostrata ) were monitoredin Lake Champlain, Vermont. Within water depths to 10 m, total displacement distances (sum ofstraight-line distance between successive position fixes) ranged from 0.6 to 4.9 km per fish.Some American eels showed substantial movement in the first few days after release, whereasothers did not; most remained in shallow water, but some moved into deeper water. Fish weredisplaced up to 0.9 km between capture and release; only two returned to within 500 m from theircapture site, indicating that little precise homing occurred. Inshore population-size estimates frommultiple mark- and-recapture methods varied from 232 to 636 fish/hectare (161-421 kg/hectare).Seven tagged individuals have been recaptured outside the study area: five at St. Jean, Quebec,one in Quebec City, Quebec, and one in St. Andres, Quebec
