Are There GOOD Invasive Species?

There are positive examples, but they are far outweighed by the negative.

That's the question one NAFC member posed to fisheries biologist Dr. Hal Schramm.

It turns out there are isolated examples of non-native species actually benefitting fisheries, but Hal is quick to point out that the prevailing conditions must be right in order for that to occur.

Some aquatic plants like Hydrilla have had a beneficial effect on certain bodies of water, and the Round Goby has become a favorite food for smallmouth and other fish. All in all though, for every positive example there are scores of examples that demonstrate the negative effects of invasives on our water.
