Raw length-weight data from a variety of populations used for computing the standard weight (Ws) equation for walleye (*Sander vitreus vitreus*).

A data frame with 34734 observations on the following 3 variables:

- popn
A unique numeric identifier for each separate regression.

- len
Total length (mm) of fish.

- wt
Weight (g) of fish.

Directly from Ken Gerow. Summarized in Gerow, K.G., R.C. Anderson-Sprecher, and W.A. Hubert. 2005. A new method to compute standard-weight equations that reduces length-related bias. North American Journal of Fisheries Management 25:1288-1300.
