Hypophthalmichthys nobilis
|
THE CRIMES: Overeats zooplankton populations in larval stage, competes with native fish and may alter water chemistry. DESCRIPTION: Large head with protruding lower jaw and downward looking eyes. Has tiny scales with grayish-black blotches giving a speckled appearance. Can weigh between 6 and 60 pounds. The Interrogation
Where are you from?
I am native to China. I live in the Huai,
Yangtze, Pearl, West (Si Kiang), Han Chiang, and Min rivers.
How did you get here?
I was brought here by a fish farmer who
wanted me to eat unwanted aquatic plant species in his fish
ponds and improve the water quality in his ponds. Little did
he know that I'm more trouble than I'm worth. Since then I have
escaped from ponds and aquaculture facilities and now inhabit
the Mississippi, Ohio and Missouri river systems..
Whats your problem?
As larvae I overeat zooplankton, microscopic
animals that float in the water. Because I reproduce very rapidly
and in large numbers, I out compete the native fish that also like
to eat zooplankton. One hazard I impose upon humans is that I jump
2-3 meters (6-10 ft) out of the water when I am disturbed. I can
cause serious injuries to boaters. You may be thinking that I am
related to flying fish but I am not.
How can we control you?
Once I escape into the wild, it is almost
impossible to control me. The most important thing to do is make
sure that I don't invade new waters. Always dispose of bait in
buckets and in live wells appropriately so tiny baby carp don't
get dumped into the water. Never dump live fish from one body of
water into another. Manmade containment structures can also be
built prohibiting me from entering new water.
Reward:
The satisfaction that you are protecting and preserving Gulf waters.
