Fisheries Assessment

On May 21 and 22, 2009, the Wells Reserve and enthusiastic volunteers set out on the Mousam River estuary to see what type of fish were in the river. Nets were set in three side channels and fished twice in a 24-hour period. Of the many diadromous species often found in Maine rivers, several adult American eels were caught. In addition, 5 juvenile herring were caught and later identified as Alosa psedoharengus — alewives! This leads us to wonder if alewives are spawning in the Mousam River estuary.


Since 2009, the Wells Reserve and volunteers have continued to monitor the fish in the Mousam.  Below is a video clip taken at the foot of the Kesslen dam, showing the alewives that are still trying to move upstream every year.
