Growth is very rapid after absorption of the egg sacs. Male walleyes mature in two to four years and females mature in three to five years. Adult walleyes are extremely sensitive to light. They feed most actively at dusk and dawn. Fry and fingerlings feed on zooplankton and insect larvae.
Adult walleyes feed primarily on fish, including the young of their own species.
What to do if you catch a tagged fish The Ministry of Natural Resources, with the assistance of high school students, have trap netted and tagged some walleyes in the Kashagawigamog chain of lakes. Anglers are asked to assist with this walleye enhancement program by reporting any tagged fish they catch. If the fish is being released, nothing has to be done. To get the proper measurement, squeeze the two lobes of the tail together. Participation was lower this year, but fun was in high gear.
