Colorado Parks and Wildlife Walleye Spawn Operation

PUEBLO, CO - MARCH 22: Colorado Parks and Wildlife native aquatics species biologist Paul Foutz, left, and CPW aquatic biologist Carrie Tucker squeeze out eggs from a walleye fish at the Lake Pueblo State Park caught during the annual Colorado Parks and Wildlife walleye spawn operation March 22, 2018. Over several weeks, the Colorado Parks and Wildlife hope to collect over 130 million walleye eggs, roe and milt which will produce game fish for anglers around the country. Thursday morning, two crews set out twice and collected both male and female walleye from 32 nets. The state-wide goal is to collect over 130 million eggs to spawn to then re-populate the state's lakes. (Photo by Andy Cross/The Denver Post via Getty Images)
