Eel Migration Count Volunteer

Location: South Wellfleet, MA
Sanctuary: Wellfleet Bay

The American Eel is the only catadromous fish found in Wellfleet Bay, with mature adults leaving estuaries to spawn in the Sargasso Sea in the middle of the Atlantic Ocean. In spring, the young eels make their way into estuaries and freshwater habitats along the Atlantic coast where they will spend the next several years reaching maturity. Mass Audubon has installed an eel ladder at the Wellfleet Bay sanctuary to allow the passage of glass eels and elvers (one-plus year-old eels) over a dike and into Silver Spring. Our Eel Migration Count Volunteers conduct daily counts from April through June.


  • Count young eels one day per week from mid-April to the end of June following the established protocol.


  • Dependable.
  • Enthusiastic.
  • Able to work cooperatively and independently.
  • All volunteers must pass a background check (CORI and SORI).

Additional Comments

  • No formal training or experience is required to become an Eel Migration Count Volunteer. Training will be provided.
  • Must be able to walk a mile and stand for an extended period of time.
  • Must be 18 years or older, or at least 14 accompanied by parent or guardian.
