Invasive Fish

In March and June 2019, USGS researchers joined partners in Treasure Coast and Central Florida where they sampled freshwater bodies for non-native fishes. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native fishes.

The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.

Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.

In November 2018, USGS researchers joined partners in South Florida where they sampled freshwater bodies for non-native fishes. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native fishes.

The introduction of non-native fishes is a problem across the United States, particularly in Florida. USGS scientists are developing a decision support tool to help natural resourece managers prioritize which species to focus prevention, detection, rapid response, and control efforts.

The Hunt For The Southernmost Snakehead. Thirty-one fishery biologists from eleven agencies participated in a two-day Fish Slam event. Thirty-five sites in Broward and Miami-Dade counties were sampled for non-native fishes.

22-23 March 2017 - Ten teams of fishery biologists sampled 28 sites amid unexpected wildfires in the Big Cypress National Preserve over the two day period. On the second day a reporter from the Miami Herald accompanied a ground crew team.

The Florida Non-Native Fish Action Alliance brings together federal and state agencies, academic institutions, and non-governmental organizations to address the need for documenting and managing the non-native fishes introduced to the state's waters.

November 1 - 2, 2016 – Eight teams of fishery biologists from the US Geological Survey (USGS), US Fish and Wildlife Service - Peninsular Florida Fisheries Office and Welaka National Fish Hatchery (USFWS), the National Park Service (NPS), Florida Fish and Wildlife Conservation Commission (FWC), Florida International University (FIU), and Zoo Miami sampled 20 sites for non-native fishes in Palm...

May 23, 2016 – Five teams of fishery biologists from the U.S. Geological Survey (USGS), Florida Fish and Wildlife Conservation Commission (FWC), the National Park Service (NPS), Florida Museum of Natural History (FLMNH), University of Florida (UF), and Florida International University (FIU) sampled 12 sites for non-native fishes in Broward and Miami-Dade counties in southeastern Florida.

Many aspects of lionfish biology are studied at the USGS Wetland and Aquatic Research Center. As part of the U.S. Geological Survey Nonindigenous Aquatic Species database, the distribution of lionfish is tracked over time.

The Florida Everglades is the largest wetland ecosystem in the United States and supports a diverse flora and fauna, including many rare species.
