Invasive Fish
Invasive Fish
An invasive species is an introduced species that has established itself and threatens the diversity and/or stability of a native species or environment. WARC researches the basic biology and environmental tolerances of these plant and animal species to provide resource managers with the ecological facts they need to help mitigate and control these problematic species. This work includes invasive fishes like the lionfish and Asian carp.

Treasure Coast and Central Florida Fish Slams - 2019
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.
Survey and Assessment of Live Food Markets as an Invasion Pathway
Live food markets may be a source of the increasing number of non-native wild invertebrate and fish species, like Asian swamp eels and snakeheads. USGS is surveying such markets around the United States to identify and document species that might be of concern if released live into the wild to assess if the live food market is a possible invasion pathway.
The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)
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.
The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)
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.
Fish Slam November 2018
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.
Development of a Quantitative Risk Assessment Tool to Predict Invasiveness of Non-native Freshwater Fishes in Everglades National Park
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.
Risk Analysis of Invasive Freshwater Fishes in Hawaii and Micronesia
Invasive species threaten biodiversity around the world, especially on islands. USGS scientists are helping to identify fish species that have the greatest potential to invade the fresh waters of Microneisa.
Fish Slam - November 2017
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.
Spring Fish Slam 2017 – Big Cypress
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.
Florida Non-Native Fish Action Alliance
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.
Fish Slam - Fall 2016
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...
