Great Snakehead (Channa marulius) has become one of the most studied of the snakehead family. Mainly because it has been found inhabiting canals in Florida. Where it is considered vermin because it is not a native fish species. There has been extensive research on its mating habits unlike the Giant snakehead and others where their activity in natural habitat has been rarely studied with much accuracy. The Great Snakehead grows fast after hatching, by eating insects and small water critters. As they get bigger they tend to hide in cover and eat – anything that moves. Including fish, frogs, snakes, crustaceans and even birds and also rodents. They like to ambush their food; they do not usually chase it.


The Great Snakehead continues to grow fast and have no natural enemies. They are prolific and produce a lot of young that have a good survival rate. So they can become very common in a body of water very quickly. Snakehead reproduces by laying eggs in a nest, they build in vegetation in shallow water. Females may produce 100 to 1000 young each time they spawn. Some species can spawn more than one time a year. The world record for this species is 9 pounds 13 ounces caught in Thailand in 2006. They are the biggest of the snakehead species, can grow to 66 pounds. But none that big have been caught on rod and reel, they can be caught in many ways, by bait fishing with live fish or frogs. The Male is territorial so sight fishing with spinners, surface lures or minnows are all common fishing techniques.
