Here fishy fishy fishy…

I remember the early crisp mornings waking up grabbing my fishing pole and heading to Lake Michigan to try and catch that trophy fish I’ve always wanted to catch. As it turns out I never caught that fish but I am still trying to reel in that trophy fish from our natural beauty we call Lake Michigan. But my childhood dreams could end up being crushed by a flying fish that smacks me right in the face! I’m talking about the Asian carp, an evasive species that is a danger to the Great Lakes Region. The Asian carp was introduced into the U.S. in the 1970’s to filter pond water in fish farms in Arkansas when a flood allowed them to escape and establish reproducing populations in the wild by the early 1980’s. These evasive species originated in Arkansas and now have been found in 23 states and are currently in the Illinois River in the direction of the Great Lakes.

A lot of you might be thinking “what can a little fishy do that could harm our Lakes?” Well the problem with Asian carp is they are a voracious filter feeder, meaning they consume up to 20% of their body weight per day in plankton (small floating organisms that are food for fish and other organisms, essential to our native fish) and these carp can grow up to be 100 lbs. and will strip away all of our natural species food supply, starving them into dwindling numbers. These fish also are known for their jumping ability when a motor boat is running. The sound of the motor drives them hurling out of the water and at boaters causing injury to people. The carp have no natural predators in North America and they lay half a million eggs each time they spawn. The U.S. Geological survey found 22 rivers in the U.S. portion of the Great Lakes that would provide suitable spawning habitat for Asian carp and the temperature of the great lakes are within the fish’s native climate range making the great lakes a perfect home for them. If this evasive species destroys our native fish we lose a big portion of our food supply and tons of fisherman will go out of business because the asian carpet is an unwanted fish due to its horrible taste

These fish almost seem unstoppable, so how are we to stop them? Well a few proposals have emerged over the years but the U.S. Army Corps of engineers is working on a few solutions that may not be introduced till 2015, but currently have emplaced and maintain three electric barriers to prevent this evasive species from enter the Great Lakes. The Great Lakes Council has been in a debate over closing the waterways but Chicago is against the idea due to the amount of business that travels through the waterways and the potential of flooding to occur. I feel that we should continue with the electric barriers for now, but we should add more barriers in tributaries of the Great Lakes and we should bump up the voltage to guarantee that they do not enter. At the same time we can have people set up charter fishing trips where they can hunt the carp with bow and arrows, harpoons, and nets while we wait until the U.S. Army of Engineers have discovered a more promising solution.
