A fish threatens three U.S. states in this week’s cartoon.

This week’s cartoon was drawn by Calvin Tran, an 8th grade student at Jenison Junior High School in Jenison, Michigan. In Calvin’s cartoon, a big fish is threatening three U.S. states. Can you tell which states they are? Michigan, Wisconsin, and Illinois are involved in a disagreement over a big fish called the Asian carp. There are many types of Asian carp, and most of them are so-called “invasive species” in the United States. This means they got to U.S. waters from elsewhere, and they are crowding out the native fish. Why might this be a problem? Asian carp can grow 4 feet long and weigh up to 100 pounds. Some types of Asian carp have been living in the Mississippi River for many years. Many people are worried about the Asian carp getting into the Great Lakes, where they could cause big problems for fisherman who make their living from catching other kinds of fish.
