Just one angler is all it would take to infect a favorite fishing spot with aquatic invasive species (AIS). At the end of a fishing trip, it’s not uncommon for anglers to release leftover minnows, worms or other unused bait into the water or to save and use the bait at another body of water. But dumping live bait into the water or on shore has helped many nonnative animals become established in new waterways. Invasive species can also hitchhike from one stream or lake to another via an angler’s gear, especially wading gear. Learn more in this week's NIE page.
