Reports from the Missouri Department of Conservation (MDC) have alerted residents to a new threat – a predatory fish known as the northern snakehead fish. This species, capable of reaching lengths of up to 3 feet, possesses the ability to move across land and extract oxygen from the air. The distinctive appearance of the northern snakehead, with a snake-like head and python-like coloration, has raised concerns about its potential impact on local ecosystems.

Angela Sokolowski, an Invasive Species Ecologist at MDC, highlighted that the northern snakehead fish poses a significant risk as one of the newest invasive species in Missouri. Originating from Asia, this fish exhibits unique survival capabilities, thriving in poorly oxygenated water and enduring extended periods out of water as long as its skin remains moist.

As aggressive predators that target native species and compete for resources, MDC officials are urging residents to take immediate action upon encountering the northern snakehead. Recommendations include killing the fish by severing its head, gutting it, or securely containing it within a plastic bag to prevent further spread.
The U.S. Fish and Wildlife Service recently listed the northern snakehead fish among the top “5 invasive species to consider hunting, catching, and cooking.” The organization even suggests culinary preparations such as fish tacos, grilling, or frying the species due to its delectable and flaky meat. Despite efforts to control its population, sightings of the northern snakehead have been reported in various regions, including Arkansas, New York, and Pennsylvania.
Female northern snakeheads can hold up to 50,000 eggs, which have a quick hatching time of 24 to 48 hours. However, not all eggs will develop successfully, with some falling prey to insects and small fish post-fertilization. While these fish typically avoid human interaction, the U.S. Geological Survey warns that they may exhibit aggressive behavior when protecting their offspring.
Designated as injurious wildlife under the Lacey Act in 2002, the northern snakehead fish is prohibited from import and interstate transport without authorization from the U.S. Fish and Wildlife Service. Previous introductions of these fish into the country were facilitated through pet stores, live food fish markets, and select restaurants, primarily in major U.S. cities.
The potential ecological threat posed by the northern snakehead fish underscores the importance of vigilant monitoring and prompt eradication measures. Residents are urged to remain proactive in preventing the further proliferation of this invasive species, ensuring the preservation of local ecosystems and native wildlife populations.
