  1. What is the technical term for these?

    Tentacles
    Stingers
    Barbels
    Whiskers
    Correct!
    Wrong!

    Barbels are found on many species of fish including catfish, bullheads, sturgeon and carp. They received the nickname of whiskers due to their presence on catfish. Do they sting you? Check out the next question!

  2. Do these sting you?

    Yes, I've been stung before
    Nope
    A few do
    Most do
    Correct!
    Wrong!

    Barbels do not sting. They are actually used for orientation and food sensing. Barbels allow for the fish to “taste” their food by touching it and “smell” the food from a distance. The stinging sensation is due to punctures by spines on the fins. Some of these spines have venom sacks which increase the pain and risk of infection. (http://pages.cs.wisc.edu/~grefe/catfish.pdf)

  3. Northern Pike periodically lose all of their teeth.

    True
    False
    Correct!
    Wrong!

    They don’t. Many anglers blame their inability to catch them at certain times due to them losing their teeth. Although they can lose and break some teeth, they never lose all of them. Most of the time they lose their teeth by choosing the wrong potential meal or just over time from wearing them down. (Minnesota Conservation Volunteer, July-August 2003)

  4. Catching and cleaning fish causes them pain.

    True
    False
    Correct!
    Wrong!

    This is a very complicated no. For ease of understanding, I’ll skip on all the big and fancy words. Fish have the right receptors to feel pain, but they don’t have the ability to process it as pain. These receptors process the “pain” and show a reaction (usually by flopping around). Fish lack the actual part of the brain that converts signals to pain. (Rose, J. et al. Fish and Fisheries 15:1, 97-133)

  5. Muskellunge (Muskies) heavily rely on walleyes as a food source.

    True
    False
    Correct!
    Wrong!

    It is a common misconception that muskies primarily prey on walleyes when available. In a study conducted with 1,092 muskies, only five had traces of walleye in their stomachs. Walleye consisted of 3.4% of their diet while 63.5% of their diet was yellow perch and various minnow species. (http://files.dnr.state.mn.us/fisheries/species/mue/mue_diets.pdf)

  6. Some fish can breathe air and travel across land.

    en.wikipedia.org)
    True
    False
    Correct!
    Wrong!

    There are many species of fish that can breathe air and cross land barriers to reach other water bodies. Some examples are eels, mangrove rivulus, and West African lungfish. Another is the snakehead (pictured above) are one of them. They have both gills and primitive lungs which allows them to breathe both above the surface and under. They got their name partially because of how they move on land. They shake back and forth in a slithering motion just like a snake.
