When I was helping the Arkansas Game and Fish doing walleye and hybrid spawning we used a capillary tube to determine if the eggs were ready.
A capillary tube is just a small glass tube. To determine the sex you just insert the tube. If it is a male, milt will run out of the end of the tube. For females, after the tube is inserted cover the end and remove it. The tube will be filled with eggs.
