These fish will end up in hatcheries to begin the next generation of northern pike in Iowa.
The Iowa Department of Natural Resources stocks the Red Rock and Saylorville reservoirs each year with spawning pike netted in an outlet of Big Spirit Lake.
DNR officials then truck spawners to hatcheries where they separate them into gender groups, noting their color patterns.
Milt from males and eggs from the females are then gathered to begin the next generation of fish that'll swim in Iowa waters.
Officials then stock the pike into lakes and select rivers in an effort to keep the state alive with fishing opportunities.
Fish are on display at the hatcheries until enough eggs are taken, then officials release them at their place of origin.
According to the DNR, they also stock muskellunge in some Iowa lakes, including Big Creek Lake, Big Hollow Lake, Brushy Creek Lake, Deep Lakes, Hawthorn Lake, Lake MacBride, Lost Grove Lake and Pleasant Creek Lake.
