Northern snakeheads (Channa argus), an invasive fish, have recently been confirmed in Delaware waters. Three adult snakeheads were collected from the Delaware portion of the Nanticoke watershed: Broad Creek in Laurel, Nanticoke Branch upstream of Seaford, and the Marshyhope at Woodenhawk. The Fisheries Section asks that any possible snakehead catches in any Delaware waters be reported by emailing a photograph and details to edna.stetzar@state.de.us

An invasive species is on the move and may be headed for Montana. Palmer amaranth, a giant pigweed, is known to have spread to at least 28 states, including Minnesota and South Dakota, but has not yet been reported in Montana. To prevent its spread into Montana, landowners are encouraged to check their fields to ensure the invasive weed is not present. It was a known contaminant in Conservation Reserve Program (CRP) seed mixes but pollinator, wildlife habitat and cover crop plantings may also been contaminated. Producers with recent conservation plantings should check their fields to ensure this invasive weed is not present.

Idaho's inspection stations are placed on major highways at or near the Idaho state line. The purpose of these stations is to inspect watercraft coming from outside of Idaho. Inspectors will look for high-risk boats that have been in quagga mussel and zebra mussel impacted states. Boats will be inspected for any attached mussels and/or standing water and owners also will be asked where they have boated in the previous 30 days. It is important that boaters arrive in Idaho with a clean, drained and dry watercraft.

Watercraft inspections are required. If you cannot get to an open inspection station you can get your watercraft inspected at a regional or area FWP office (PDF | 503 KB).
