There are unwanted visitors threatening to make their home in the Great Lakes. Originally coming from Asia, the fish immigrated to the Mississippi River eventually making their way to the Great Lakes. Let’s take a look at the problem, the causes and effects, and the possible solutions of the Asian Carp Invasion.
Bighead, Silver, Grass, and Black Carp, even though each its own distinct species, all fall under the name “Asian Carp.” They can weigh anywhere from 60 to 110 pounds, and range from 40 to 60 inches in length. Asian Carp are considered an “invasive species,” an organism that is not native and has negative effects on our economy, environment, or our health.

Some Michigan chefs decided to try to experiment with Asian Carp to test this theory. Many of the chefs found that is nearly impossible to serve Asian Carp as a fillet because of their many bones. Some say that the fish doesn’t have a pleasant taste either. Chefs decided that it would not be worth the hassle to serve the fish on their menu.
Funding a solution to Asian Carp is also a problem. Some proposed solutions are estimated to cost over 20 million dollars! Although in comparison, it is very little to the seven billion dollar fishing industry that is endangered. An idea raised that manufacturing nitrogen and bubbling it in the water could eliminate oxygen and creates a barrier. This idea came from pollution from pollution of the Chicago shipping Canal. Since the water was anaerobic from all of the pollutants, fish would not pass through it. The upside to this is that it is completely reversible and environmentally friendly. The bubbles would still be able to convert to dissolved oxygen in water to gas form, which then would rise to the surface and escape back into the air.
It is estimated that this would cost between $15 and $20 million to operate each year.
In 2009, and attempt to poison Asian Carp killed 90 tons of fish and also cost the United States three million dollars. The Illinois Department of Natural Resources dumped over two thousand gallons of rotenone in to the Chicago Sanitary and Ship Canal. Rotenone is a toxin to certain fish and is said is to be harmless to humans. The attempt failed and among the 90 tons of dead fish, only one Asian Carp was found.
Series of electronic barriers are used to prevent Asian Carp from entering the Great Lakes as well. What are the plans to stop the Asian Carp? The White House has taken action and a 78.5 million dollar...
