|This the black
carp. It was caught in the wild for
the first time back in March of this year by commercial fishermen. Horseshoe Lake is in Illinois adjacent to
the Mississippi River. The good news
is that the fish tested out to be a triploid, in other words, sterile. The
black carp is a native of eastern Asia. It eats snails and clams and was
introduced for that reason – as a biocontrol of a snail that is the
intermediate host of a catfish parasite.
In 1994, about 30 of them escaped a fish farm when a dyke was breached
by flood waters. None were ever recaptured.
