Asian Carp is already quite famous for its aggressive behavior. Its name comes from the fact that this species originated from Asia and was mistakenly introduced in the United States.
Unfortunately, Asian Carp is a pest, because it competes with the native fish for food and causes the imbalance in the Great Lakes ecosystem. Furthermore, because of their aggressive behavior, they can harm the fishermen as they can jump 10 feet above the water surface.
A team of researchers from the University of Illinois and U.S. Geological Survey has come up with an ingenious idea to make the lake water similar to carbonated soda water to see how the fish would react.
During the study, scientists infused the water with recycled CO2 gas to affect the movement of the Asian carp in a research pond at the USGS Upper Midwest Environmental Sciences Center in La Crosse, Wisconsin.
As a result, the carp species evaded the CO2-infused water. This means that they cannot live in it. However, scientists have not established yet the other effects that carbon dioxide will have on the other fish and creatures in the lake waters.
Still, this method could prove to be very useful in the future to prevent the spread of the invasive Asian carp in the Great Lakes. According to Michael Donaldson, lead author from the University of Illinois, these findings are very positive as CO2-infused waters can definitely stop the migration of Asian carp.
Nevertheless, Joe Amberg of the U.S. Geological Survey believes that they still need to make more experiments and tests to establish whether CO2 will be able to control the movements of the invasive species is a natural river, not in a research environment.
Asian carp is a pest that thrived in the United States inland water, spreading and consuming a tremendous amount of plankton vital for the native fish species. Furthermore, they always pose a significant threat to anglers and boaters that use these waters for fishing.
Scientists now have to determine the long-term effect of CO2 on native species and the quality of water. If future tests show that there are no other side-effects of carbon dioxide on the lake environment, then this method will become the primary weapon against the invasive Asian carp.
