The Lionfish Challenge is a free summer-long (May 24-September 2, 2024) lionfish tournament open to recreational and commercial competitors of all ages around the state of Florida. Our goal remains the same — remove as many lionfish as we can in just four months. Are you up for the Challenge? See also:

The lionfish is a striking yet destructive invasive species that has found its way into the waters of North America, leaving a trail of ecological havoc in its wake. In this blog post, we delve into the alarming impact of lionfish invasion on our local marine environments and the urgent need for concerted action.

NOAA's Flower Garden Banks National Marine Sanctuary (FGBNMS) is partnering with Lionfish Invitational, and others to use trained divers to help conduct research and remove invasive lionfish within FGBMNS. This multi-day event is a science-based research expedition in which 11 dive teams work to remove as many lionfish as possible, while also recording helpful data on lionfish activity and sightings. In addition, a science team of 8 divers conducts surveys to determine what species, quantities and sizes of fish are present at each designated site before and after the removals. Applications are due Mar 1, 2024. The 2024 expeditions will take place on the following dates:

• ​June 23-27, 2024
• August 11-15, 2024
• September 8-12, 2024

In early December Washington Department of Fish and Wildlife (WDFW) Police received information that a Seattle market was selling live “green crabs”. The Seattle seller had bought the live green crabs from a seller in Massachusetts with the intention of selling them for crab stock and soup. The crabs were destroyed by WDFW Police officers.

The green crab is considered one of the most invasive species in the marine environment. It has few predators, aggressively hunts and eats its prey, destroys seagrass, and outcompetes local species for food and habitat. Green crab could potentially damage Alaska’s multi-billion dollar fisheries industries, especially for salmon, crab, and mariculture operations. There are three simple steps you can take to help find, remove and report these crabs on your local beaches. Find it, Keep it, Freeze it!

The National European Green Crab (EGC) Management and Control Plan was developed by a multi-agency European Green Crab Working Group for implementation by the Aquatic Nuisance Species Task Force following final approval.

The purpose of the 2023 EGC plan is to provide guidance for efforts to prevent future introductions, to rapidly detect and respond to new invasions of EGC before they become established and create ecological and economic damage, and to manage current populations that pose an undue threat to resources of importance for ecosystems and local cultures. The 2023 EGC plan proposes to update the 2002 plan by providing a more focused set of approaches for future management, based on significant changes in the distribution of EGC, new technologies available for identifying sources and mechanisms of spread, better information regarding the tradeoffs for different management efforts, and new methods for data management and sharing. The 2023 EGC plan also describes current strategies for coordinating the activities of scientists, resource agencies, Tribal and First Nation organizations, and other entities.

The Florida Fish and Wildlife Conservation Commission (FWC) is excited to announce the 7th annual Lionfish Removal and Awareness Festival May 15 and 16 at AJ’s Seafood and Oyster Bar and HarborWalk Village in Destin. Come out and celebrate the fight against invasive lionfish with the FWC and Destin–Fort Walton Beach. Activities will include fillet demonstrations; family-friendly games and activities; art, diving and conservation booths; and the world’s largest lionfish spearfishing tournament, the Emerald Coast Open. Learn more by visiting FWCReefRangers.com. The 2021 Lionfish Challenge removal incentive program will begin May 21 and continue through Labor Day, Sept. 6. More details on how to get rewarded for your harvest coming soon to FWCReefRangers.com.

The Chesapeake Bay Nutria Eradication Project (CBNEP) historically used working dogs to locate invasive nutria populations across the Delmarva Peninsula. As nutria populations decreased, the transition to detection and detector dogs was necessary. Dogs can be trained to smell the evidence of specific animals and plants in an area without visual identification.  

Governor Wes Moore is calling on the federal government to declare the expanding population of invasive fish species—including blue catfish, flathead catfish, and snakehead—to be an ongoing commercial fishery disaster in the Maryland waters of the Chesapeake Bay. The governor sent a letter [Mar 2023; PDF, 2.4 MB] to U.S. Commerce Secretary Gina Raimondo requesting the declaration under provisions of the Magnuson-Stevens Fishery Conservation and Management Act and the Interjurisdictional Fisheries Act. The declaration would qualify Maryland for federal fishery disaster assistance.

Missouri Department of Conservation (MDC) fisheries biologists say that the Show-Me-State has another aquatic invader to be on the watch for. It's already been detected in the Mississippi River near St. Louis—and anglers might be the first line of defense. The round goby (Neogobius melanostomus) is native to the Black and Caspian Seas between Europe and Asia and was brought to the U.S. by way of the Great Lakes in cargo ship ballast. Since then, the invasive fish has made its way down the Illinois River and has been confirmed just across the Mississippi at Alton, Illinois. MDC encourages anglers to take photos and email MDC with details if they encounter any round gobies. Anglers should report the sighting and email photos to MDCgoby@mdc.mo.gov.
