Interestingly, it has been speculated by biologists that before stocking programs began in the 1920's by the Lands and Forests, yellow walleye may not have existed in Nipissing. Genetically distinct from the yellow pickerel, another species, the blue pickerel was documented by W. Harkness in the 1920's. Now rare, it has been suggested that this smaller species hybridized with the stocked yellow pickerel. The lasting genetic effects of hybridization of the two species may account for the slower growth of the pickerel now inhabiting the lake. Yellow perch which are also abundant in lake Nipissing, are a valuable food source for the walleye.
Walleye fishing is best near twilight.
Light sensitive walleyefeed in the early morning and evening. However, overcast conditions produce good catches during the daytime. Still fishing with a live shiner, trolling or casting with a worm harness or bouncing a jig with a worm off the bottom while drifting all entice walleye to bite in the spring. Although it can heartbreaking to see that big one swim away, any walleye over 18 inches in length should be released as these large fish produce the most young. This will ensure that fish stocks remain at a high level for the future.
