December 4, 2003Snakehead fish now banned from NebraskaBy REGIS NEUROHR
The Interior Department said three species of snakehead have been recorded in the United States, in the states of California, Florida, Hawaii, Maine, Maryland, Massachusetts and Rhode Island. Several northern snakeheads, which can survive winters in cold water as far north as canada, have been caught by anglers from the Potomac river in Maryland and Virginia, an indication that they are reproducing. There are 28 species of snakehead fish (Calamichthys calabaricus, Calamoichthys calabaricus, Hepetoichthys calabaricus - Call me "Cal" for short...) and they are described as 'the baddest
The fish, which is native to China and West Africa, has primarily been imported to the United States by seafood sellers and aquarium shops. Such sales would be banned under an impending Federal Interior Department's proposal. Snakefish wriggle long distances over land and then introduce themselves into ponds and riverbeds. They then voraciously eat them bone-dry of fish, insect and plant-life. When the food supply runs out, snakeheads slither out of the water onto dry land, creeping along with their fins for up to four days driven by hunger in search of the next aquatic smorgasbord. This predator will even asphyxiate if they are prevented from breathing air. All 28 species of snakehead can tolerate low oxygen conditions in water because they are air breathers from an early age. When prevented from water surface access, adult snakeheads will die due to lack of oxygen. The snakehead, most which normally grow to 3 feet long (Some species exceed this length), exhibits an insatiable appetite for any kind of flesh and will even eat their fry. The fish has an ugly wide mouth and heavy scales, making it look like a snake's head. It can swallow prey as large as itself. Typically, adults snakeheads exist on fish, frogs, birds and small mammals when in proximity. Maryland is moving aggressively to solve its snakehead problem, with officials announcing that poison will be used to kill the fish to stop the predator from spreading into other waterways. This
State game officials sprayed enough poison at sunrise to kill every fish in the murky pond. By mid-morning, the water was pocked by circular ripples of fish breaking the surface and gasping for air. To show the predatory nature of the fish, one game official cut open a 4-inch juvenile snakehead that floated to the surface. Inside were two tiny other fish, each still whole. Nearly 100 snakeheads had gone belly-up. About 20 game officials wearing rubber boots and rubber overalls waded into the pond with nets to scoop up the dead and struggling fish. A fence was built to prevent any last-minute escape by
State game officials said the poison should dissipate within two days and that they would restock the pond with fish next spring if the owners wanted them to. An established (reproducing) population of ' bullseye' snakehead was found in Broward County, Florida. This is the largest of the snakehead species. It commonly grows to a length of about four feet. State biologists postulate that this species may have been introduced intentionally as a food fish, released by aquarium hobbyists or escaped from a fish farm. A northern snakehead was caught from Newton Pond in Sudbury, Massachusetts. The likely source of this fish was the live fish market. Specimens of the 'Giant' snakehead have been collected from open waters in Maine, Massachusetts and Rhode Island. These snakeheads likely were released by aquarium owners whose "pets" grew too large or too expensive to feed. The 'Giant' type is the most predacious snakehead species and has been known to attack humans. Live northern snakeheads are readily available in the seafood markets of Boston and New York. California Fish and Game personnel collected a snakehead in Silverwood Lake in the San Bernardino Mountains east of Los Angeles. The 'Chevron' species of snakehead was established on the Hawaiian island of Oahu in the late 1800's, where it is was cultured as a food fish. According to U.S. Fish and Wildlife Service law enforcement, records show that 16,554 live snakefish were imported into the U.S. between 1997 and 2000. The trend has been toward an increase in recent years. The states of Alabama, California, Florida, Kentucky, Texas and Washington have all recorded snakehead-related illegal activity, confiscations, citations or investigations within the past two years. Live northern snakeheads destined for food markets have been confiscated in markets in Washington, Texas and Florida. Snakeheads are also available for purchase over the Internet. The snakehead has few friends, even among animal activist groups. People for the Ethical Treatment of Animals, a group which normally leads the fight for animal protection issues, said it has no sympathy for snakeheads and supports the state plan to kill them. Still, the snakeheads have attracted a cult following. Their fate has been closely tracked by
The Nebraska Game and Parks Commissioners have decided to approve a bounty purchase program. The NGPC will purchase snakeheads currently owned in private aquariums at prices of $10 for those under 12 inches, $20 from 12 to 24 inches and $50 for those over 24 inches. These and other preventative steps must be taken now before
Frankenfish invades the Missouri River. The female snakehead is theoretically capable of hatching as many as 180 fry up to 40
times a year! The female northern snakehead is capable of spawning five times a year. Northern snakeheads can live under the
ice of northern climates. The northern has become the most available species of live snakeheads in the fish markets of New York and Boston.
Boaters who beach up on the shore this summer to enjoy the cool water on a hot day will now have something else to think about.
