MADISON, Wis. (AP) — Gov. Scott Walker has signed a bill that loosens fish farm regulations.

Under the Republican bill, fish farms no longer need permits to discharge material into a wetland if the wetland was created for fish farming. Natural water bodies can serve as fish farms and farms wouldn't need permits to construct or enlarge artificial water bodies connected to a navigable waterway. New permit conditions will be prohibited unless needed to meet water quality standards.

Walker signed the bill Friday at Star Prairie Trout Farm in St. Croix County.

The governor signed another bill at the farm that allows small gas stations to advertise prices by the half-gallon The bill is designed to accommodate stations with non-digital pumps that don't go beyond $1.99 or $2.99.
