Arkansas man charged for illegally selling Asian carp in Michigan
A man was charged with 12 felony counts for illegally selling live Asian carp in Michigan. And he wasn't too inconspicuous - "grass carp" was apparently written on the side of his truck.
From the Michigan DNR:
...the Attorney General's Criminal Division has charged an Arkansas man with 12 felony counts of possessing and selling live Asian carp in violation of state law protecting against the spread of invasive species. The charges follow a joint investigation by the DNR's Special Investigation Unit and Commercial Fish Enforcement Unit.
Grass carp are a type of Asian carp. Grass carp have been illegal to sell in Michigan for decades because the invasive species is a voracious plant eater.
Officials say grass carp "could potentially remove all vegetation from a body of water at the expense of native species."
The fish were imported in the 1960's and have been used to control weeds in ponds.
State officials say David Shane Costner, 42, of Harrisburg, Ark., had 110 grass carp housed in a semi-truck. Costner was working for Farley's Arkansas Pondstockers.
More from the MDNR:
Costner allegedly traveled around the state, conducting sales of the illegal carp from store parking lots. The trucks also contained live fish species permitted under state law, including channel catfish, largemouth bass and fathead minnows. On May 16, 2012, Costner allegedly sold two of the live grass carp to undercover DNR investigators in Midland, Mich.
David Eggert of MLive reports Costner's truck had the words "grass carp" written on the side.
The wildlife agency received a tip that Costner had been selling illegal carp at several locations in southern Michigan and the west side of the state, Golder said... Costner could not be reached for comment. A secretary who answered the phone at Farley's said he no longer works there.
Grass carp are just one of four species of Asian Carp officials are worried about. And Grass carp appear to be the least of their worries when it comes to threats to the Great Lakes.
The Asian Carp Regional Coordinating Committee lists three Asian Carp that are of concern - Grass carp are not on the list:
There are three species of Asian carp that are considered invasive and a threat to the Great Lakes: the bighead, silver and black carp. Silver and bighead carp are filter-feeding fish and consume plant and animal plankton. Asian carp can grow to large sizes: some as large as 110 pounds, though the average size is around 30-40 pounds. Bighead and silver carp are voracious eaters, capable of eating 5-20 percent of their body weight each day. They consume plankton—algae and other microscopic organisms—stripping the food web of the key source of food for small and big fish. Black carp differ in that they consume primarily mollusks, and threaten native mussel and sturgeon populations. They can grow to seven feet in length and over 100 pounds.
