Walleye and Northern Pike Fish Age-Size Male/Female Ratio Comparison Chart for Northern Ontario Canada

Walleye & Northern Pike
Fish Age-Size and Male/Female Ratio Chart

This chart shows typical Walleye and Northern Pike sizes for different ages as well as Male/Female Ratios for Wabatongushi Lake and our region of Northern Ontario Canada. We are in the mid boreal forests of Northern Ontario so Walleye and Northern Pike in Southern Regions will grow much faster, possibly twice as fast, as our region. However, our Walleye and Northern Pike tend to live much longer, perhaps twice the age or more.

*All figures and statements are a compilation from various scientific sources that have been significantly generalized. Numerous exceptions to this chart should be expected.

Male Walleyes mature at approximately 3 years of age, generally grow to approximately 20”/51cm and have a life expectancy is 15-20 years. Female Walleyes mature at approximately 5 years, grow faster than the males after age 4 and can live considerably longer.			Notes	Male Northern Pike mature at approximately 4-5 years, generally grow to approximately 28”/71cm and have a life expectancy of 15-25 years. Female Northern Pike mature at approximately 5-6 years, grow considerably faster than males and live considerably longer.
The larger that female Walleye and Northern Pike become, the better spawners they are. Although egg production per pound decreases slightly as female Walleye and Northern Pike age, egg size, health and viability increase significantly with age. It is not known if female Walleye and Northern Pike ever do reach a size and age where they become over-mature and unable to spawn. -Larger Walleye and Northern Pike become so partially because of age, and partially because they are genetically larger. If larger fish are released they continue to pass their larger genes into the gene pool. -For both Walleye and Northern Pike the best eating are 5-9 year old fish because of fillet size, quality of the meat and superior taste. Walleye 14”-18” and Northern Pike 24”-30” are best eating, and larger fish are best spawners.
