The Alewife (Alosa pseudoharengus) is a type of river herring which
returns every spring from the ocean to spawning grounds in upstream
ponds. Although there are fish ladders built around dams, many of these
are not in good repair, or are of poor design. Between these
obstacles to swimming, and pollution levels, the Alewife population is
in danger.
The Parker River Clean Water Association conducts a count of the Alewife fish every spring from early April 1 to mid May in order to determine how many fish are now able to make their way upstream. Recent counts show a decline of over 70% in comparison with counts from the 1970s. PRCWA relies on volunteers from the community to help us in the fish count. We hope that you will join us in this effort!
