New invasive species app for public promotes early detection of aquatic invaders

The Pennsylvania Sea Grant has developed an app for the public — primarily anglers, boaters and other users of waterways — to identify and report aquatic invasive species.

These invasive species can harm natural resources and impact public use of waterways.

According to the Pennsylvania Fish and Boat Commission, some of the aquatic invasives include: New Zealand mudsnail, European ruffe, sea lamprey, hydrilla, spiny water flea, Asian clams, northern snakehead and more.

Nearly every watershed in the state has invasive species that include algae, plants, fish, reptiles, invertebrates and pathogens. That’s according to Pennsylvania Sea Grant, which is part of the National Oceanic and Atmospheric Administration’s (NOAA) Sea Grant, a network of 34 Sea Grant programs focused on marine and Great Lakes resources. Penn State Behrend administers the Pennsylvania program.

The problem is if an invasive species becomes established, it is difficult to eradicate. Invasive species are often unknowingly spread from one water body to another via boating or fishing gear, or through the release of aquatic pets that are no longer wanted or suitable for indoor conditions.

To help prevent the spread of invasive species, the U.S. Fish and Wildlife Service awarded a grant to the Pennsylvania Sea Grant to develop an app, which is based on its publication “Pennsylvania Field Guide to Aquatic Invasive Species.”

Prevention tips in the field guide and app will help anglers, boaters and other people on the water about how to properly clean gear and ensure that aquatic invasive species are not transported from one water body to another.

Sara Stahlman, extension leader for PA Sea Grant said: “This will take early detection of invasive species to a new level, allowing resource managers in Pennsylvania to easily receive new reports and get a one-up on developing possible rapid response actions.”

The “PA AIS” app is now available in the Apple App Store, with an Android version anticipated. To learn more, visit the PA Sea Grant website.
