The men's rowing team from Washington University in St. Louis got quite a shock out on the water during a practice run. As they were making their way to shore, hundreds of Asian carp leapt through the air, surrounding their boat.
It might have looked like some freak occurrence out of a horror film, but it's actually not all that uncommon in parts of the U.S. A survey conducted by the Proceedings of the Northeastern Recreation Research Symposium found that "nearly three quarters of Illinois River town users who have observed an Asian carp jump have been hit by one."
Silver carp can jump up to ten feet, so boaters and water skiers, particularly in carp-dense Illinois and Mississippi rivers, should be cautious.
Although it may look like they're targeting humans, the carp are only responding to the disturbance of the boat propellers. Basically, they get spooked and start jumping.
Not only can carp reek havoc for boaters, they're also harming North American waters. According to Ontario's Invading Species Awareness Program, they are threatening Canada's native fish.
"They could potentially eat the food supply that our native fish depend on and crowd them out of their habitat."
Asian carps were brought into North America from Asia during the '60s and '70s. It's a good example of why people shouldn't import live fish from other countries or release live fish into our waters.
