The Southwest Florida waterways are home to numerous non-native freshwater fish species. These nonnative fish may be causing detrimental changes to our native fish communities, particularly as the number of new species continues to increase. All but two of these fish were introduced illegally as the result of releases of unwanted pets and food fish, or due to the flooding of aquaculture ponds.

The Southwest Florida CISMA is hosting two Southwest Florida Non-Native Fish Round-Ups this year, one on April 28th at Sugden Park in Collier County, 4284 Avalon Drive Naples, FL 34112; and one on May 5th at Lakes Park in Lee County, 7330 Gladiolus Drive Fort Myers, FL 33908, to raise public awareness about the potential negative impacts of releasing non-native fish into Florida waters, and to encourage anglers to target these nonnative species for consumption. The Round-Ups will also gather data about non-native fish distribution and abundance that can assist with future management.

Each Round-Ups will be a two-day event open to teams of 1-4 anglers (shore or boat) fishing in the Southwest Florida CISMA area: Collier, Lee, Charlotte, Hendry and Glades Counties. Check-in will be 5pm on Saturday, and weigh-in will begin at 4 pm on Saturday. Additionally, there will be a Kids Only Fishing Blitz at the Check In Locations from 4pm-6pm each Saturday. PRIZES will be awarded each weekend to the team catching the largest fish, largest aggregate catch, and largest aggregate catch during the Kids Fishing Blitz. A "Slam" prize will also be awarded to the team that catches the greatest number of diverse nonnative species between the two weekends.


This is a team event with 1-4 anglers per team. ALL anglers must register online as individuals and include the Team name that you are on! All anglers must REGISTER HERE by 6:00 pm on the Thursday before (April 26th or May 3rd) your planned competition weekend. Anglers may register for BOTH weekends by April 16th.
