The Utah Division of Wildlife Resources set out on an early March morning on Willard Bay to catch walleye and retrieve their eggs. The millions of eggs that are collected will be mixed with milt, sperm from a male fish, and fertilized right on the dock at the bay. Biologist put the eggs through a specialized high-pressure treatment while the eggs are going through the fertilization process.

After the eggs are held at 9,500 PSI for 10 minutes, the result is a sterile fish egg. The egg will develop into a fish that is unable to reproduce in the wild. The eggs will grow at a fish hatchery in Springville and will eventually be release back into Willard Bay. Sterile fish are beneficial in providing a controlled and consistent walleye population for anglers.
