CHEYENNE, Wyo. (AP) — The Wyoming Game and Fish Department has devised new regulations on boat inspections intended to keep harmful aquatic invasive species such as zebra and quagga mussels from entering the state.

The regulations require any watercraft transported into Wyoming from March 1 through Nov. 30 to be examined by an authorized inspector prior to launching in any water in the state.

Any watercraft that has been in water infested with zebra or quagga mussels within the prior 30 days is required to undergo a mandatory inspection by an authorized inspector prior to launching in Wyoming year-round.

There will be invasive species inspection stations at ports of entry and elsewhere in the state starting April 15.
