In March 2021, USGS researchers and partners conducted the first-ever Virtual Fish Slam. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native freshwater fishes.
March 14-18, 2021 – Sixty-three fish biologists and university students from 10 organizations participated in a week-long Virtual Fish Slam. Due to COVID-19, participants sampled local sites of their choosing and submitted their data digitally. Thirty-three sites throughout Florida were sampled for non-native fishes. Sampling gear included electrofishing boats, backpack electrofisher, minnow traps, cast nets, seines, dipnets, hook and line, and underwater camera. Participants collected or observed 20 species of non-native fishes. For general information on Fish Slam events, please see the webpage for the Florida Non-native Fish Action Alliance.
While we missed the comradery and getting to see everyone’s fish collections at the end of the day, the flexibility of this slam allowed people to sample when and where their schedule permitted. This allowed for a broader range of participants who may not have been able to travel to a typical Fish Slam. This also offered some of the participants, particularly in the northern part of the state, the opportunity to explore infrequently sampled sites for non-native species close to home.
A new locality collection for the Jack Dempsey cichlid, Rocio octofasciata, was made by the Florida Fish and Wildlife Conservation Commission near the Little Wekiva River. (Purple arrow on map)
Data from these collections and all our previous Fish Slams are publicly available via the USGS Nonindigenous Aquatic Species database. Several collections are cataloged at the Florida Museum.
