White Perch

 

Where did white perch come from?

  • White perch came from the Atlantic coastal region in brackish water.
  • They first appeared in the Great Lakes in the 1940s through the Erie and Welland canals.

 

Why is it a problem?

  • White perch are predacious and opportunistic feeders, often feeding on the eggs of walleye.
  • They compete for zooplankton which may lead to algal blooms.
  • White perch have hybridized with native white bass in western Lake Erie.

 

How do white perch spread?

  • Unauthorized stocking has been a source of spread to inland waters in other states.
  • White perch have been transported through boating.

 

How do we control white perch?

  • Report suspected findings in inland waters.
  • Education and inspection efforts can limit the spread of invasive species.
  • Clean ballast tanks to remove sediment regularly.
  • Remove fouling organisms from hull, piping, and tanks on a regular basis and dispose of any removed substances in accordance with local, state and federal regulations.
