Attempting to estimate the weight of a pike from its length is a risky business. For any given length pike can vary in weight by a great amount. There are a number of factors which can govern overall weight - the quality and availability of food, and the length of time which has passed since the pike's last meal being just two. Weight also varies depending ontime of year and the state of development of the ovaries in female pike.
The table above is based on that compiled
by Fred Buller to cover a range of possible condition variations.
Length measurements are tip of snout to fork of tail. To convert
extreme length (snout to tip of tail) to fork length divide by
1.055. To convert fork length to extreme length multiply by 1.055.
Weight Calculation Formula
There is also a formula
that might be of some use in calculating approximate weights
of pike (in pounds) if you have the girth and extreme
length measurements (in inches). The formula is:
weight = length x girth x girth ÷ 800 (W = L x G x G ÷ 800)
