The Iowa Department of Natural Resources has been dealing with an undesirable fish in Lake Sugema in southeast Iowa recently, and it wants to prevent the gizzard shad from spreading to other area lakes. Chad Dolan is a Fisheries Biologist with the department. He says gizzard shad can infiltrate small lakes and rivers and affect the food chain.
The fish can cohabitate with other species in larger lakes, Dolan says, but in smaller lakes like Sugema and Lake Darling, gizzard shad can be problematic for game fish. The DNR has created a drawn out fish kill at Sugema to relieve the lake of gizzard shad, which Dolan says is something he hopes he doesn’t have to do for Lake Darling.
Possession of live gizzard shad is illegal in Iowa, Dolan adds, and reminds residents and anglers alike to keep gizzard shad away from smaller bodies of water.
