Eco details: 
  • As with many great lakes species, walleye populations have declined due to overfishing, habitat damage, and non native species that both compete for food or prey on walleye.
  • This species is naturally resilient to fishing pressure and although it has suffered a few drastic declines, it is now considered to be rebuilding.
