(AP) — The state Game and Parks Commission says new regulations are in place to restrict the movement of baitfish collected in eastern Nebraska.

The commission says it’s now illegal for individuals or bait dealers to transport any baitfish away from the Missouri River that were collected downstream of Gavins Point Dam. The restriction also applies to rivers and streams east of U.S. Highway 81 from the South Dakota border to York, north of Interstate 80 from York to Lincoln, and east of U.S. Highway 77 from Lincoln to the Kansas border.

Officials say they’re concerned about the movement of small Asian carp and white perch, along with other invasive species.
