Lionfish, tiger prawns, zebra mussels oh my! What does each one of these aquatic critters have in common?
They are all nonnative species that have been spotted in the United States, and when introduced into ecosystems outside of their native range, can negatively impact humans, the environment or the economy — giving them the notorious label of “invasive.”
You can help by participating in this year’s invasive fish roundup, April 26- 28 in Fort Myers.
We all know an example of an invasive species, but what exactly are these organisms that cause over $120 billion annually in damage to the U.S. economy? Invasive species are nonnative by definition and occur outside their geographic range. These organisms were introduced by people either intentionally or unintentionally and can harm the environment, economy or humans.
If the organism is not from here and is not causing harm, you’ve got yourself a nonnative, which, when kept under the right conditions, can be harmless to our pets, favorite foods and prized landscaping.

When do nonnative species become a real problem? When these organisms become established in our environment, meaning a self-reproducing population. Once that happens, they are often here to stay, and so are the issues they create for land managers, local ecosystems and costs associated with research and removal.
What’s the answer? Education, prevention, early detection, rapid response, and removal. The most effective way to battle invaders from taking hold is to not release them out to begin with. Some of these introductions may have been by accident through unprocessed shipping materials, adverse weather, escapees, etc. They may be hard to foresee, but legislation, research and municipal ordinances can help reduce the chances of unintentional introductions.
Education on the impacts of invasive species can help prevent folks from considering releasing their pets or choosing plant species that are legal and have less of a chance of getting out of hand and out of the yard.
Working groups like CISMAS (cooperative invasive species management areas) put on events like the 2024 SWFL CISMA Invasive Fish Roundup where the public can help take a bite of the freshwater fish problem in our area. During the 2023 event, 91 anglers brought in over 5,639 invasive freshwater fish, weighing it at a whopping 2,648 pounds. During the event, data were collected to benefit research, and fish were used for educational purposes, consumed by the anglers and anything unclaimed was used in compost.
This year’s event, April 26-28, is gearing up to be the best yet. Participating anglers can receive prizes, and during the weigh-in on April 28, there will be plenty of fun, educational stations and activities.
