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.

Fish Slam December 2023
Fifty-four biologists from nine organizations, including USGS, participated in a two-day Fish Slam event on December 13 - 14, 2023 in Southwest Florida.
Fish Slam May 2023
Fish Slam events link research institutions such as museums and universities with federal, state, and local government agencies that possess expertise and field equipment to collect nonnative fishes, providing unique access to specimens for these institutions.
Fish Chat and Slam December 2022
Fifty-seven fish biologists from 12 organizations participated in a three-day Fish Chat and Slam event in South Florida.
Southwest Florida Fish Slam – Spring 2022
Forty-two fish biologists from seven organizations participated in a two-day Spring Fish Slam event in southwest Florida. Fourteen species of non-native fishes were collected or observed.
Virtual Fish Slam - March 2021
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.
Early Detection and Rapid Response: Removal of Newly Introduced Non-native Marine Fishes to Prevent Invasions
USGS WARC works with partners on early detection and rapid response (ED/RR) efforts, rapidly removing newly introduced non-native marine fishes from Florida’s coastal waters to prevent invasions.
Non-native Marine Fishes: Tracking Distributions with the USGS Nonindigenous Aquatic Species Database
WARC scientists work with local partners to verify and document sightings of non-native marine fishes.
Fish Chat and Slam November 2019
Fifty fish biologists from 15 organizations participated in a three-day Fish Chat and Slam event in South Florida on November 5-7, 2019.
Comparative Freshwater Fish Toxicity Testing of Antimycin A
Researchers are investigating the influence of Antimycin A on invasive carp and non-target fishes by measuring the effects of a novel species-specific bait formulation.
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.
