Nonnative: Snakehead - Channa | |
Snakehead - Channa Description: Air-breathing, torpedo-shaped fish with flattened head and toothed jaws; long anal and dorsal fins without spines; they resemble bowfin in behavior and appearance, but are distinguished by a long anal fin. In addition their is a bony-plate in the lower jaw (throat area) of a bowfin that is lacking in snakeheads. Lower jaw extends beyond upper in snakeheads, and they have tubular nostrils. Species: Two genera, 21-26 species Range: Native range Pakistan, Malaysia, and southern China and parts of tropical Africa. The Bullseye Snakehead's distribution remains centered in the Margate/Coral Springs/Pompano Beach area. To the south this population is bounded by the North New River Canal (G-15), L-36 Canal to the west, and the Hillsboro Canal (G-08) to the north. This is the only area from which Snakeheads have been documented, although FWC has received numerous reports of Bullseye Snakehead elsewhere these have all turned out to be similar-looking native fishes such as the Bowfin. Habitat: In canals, typically associated with overhanging shoreline vegetation, dense submersed vegetation, and debris; tolerant of stagnant waters due to air-breathing capabilities. Spawning Habitats: Spawn primarily from March through May with a secondary peak in August; adults occasionally seen herding young in shallows until 6-8 inches long; a sample of ripe females contained an average of 4,700 ready to spawn eggs. Feeding Habits: Bottom dwelling, ambush predator that feeds primarily on small fish and crayfish, but occasionally eats a wide variety of prey including turtles, toads, lizards, snakes, and insects. Age and Growth: May grow to more than three feet and weights of about 15 pounds. Potential Concerns: The entire family Channidae is prohibited. The bullseye snakehead is already established in south Florida. It is a popular sport fish in its native range. | |
