Fish Fun!
Math Made Easy

You work for the Ohio Division of Wildlife as a fish biologist studying bass in Lake (make up a name for your lake and write it on the line) ________________. 

Beaver cartoonYou caught 30 bass in your net, tagged them, and then released them back into the lake. The next day you went back and caught 9 bass in your net, 2 of which were tagged. What is the estimated population of bass in the lake? Follow the Peterson formula below to find out.

30 (bass tagged) x 9 = 270; 270/2 (tagged bass caught) = number of bass in the lake

How many of these fish below can you match with their names? Draw a line from the fish to its name.

Largemouth bass, bluegill, channel catfish, walleye, lake sturgeon

Four of these fish are common in Ohio, but one is an endangered species. Do you know which one?
