Abstract
The purpose of this investigation was to study the effect of current spawning procedures on walleye egg survival, to reduce the effect of these procedures on survival, and to evaluate different techniques to improve egg fertility and subsequent survival and hatch. Findings indicate a 4.0 to 7.0mm egg depth using 16-ounces of eggs is most desirable for good sperm cell distribution to the eggs.
