LDWF says if you think you caught a Northern Snakehead, do not put it back in the water. Instead, take a side view picture of the fish, kill it, double bag it, freeze it and contact the Aquatic Invasive Species Hotline at (225)-265-3977 or AquaticInvasives@wlf.la.gov. Also, be sure to note the exact location where you caught the fish. They say though there has not been any reported sightings of the fish in Louisiana, there has been some in Mississippi, which is why they want to keep tabs on any that may be spotted in Louisiana.
