  • Weird Fish


    A paddlefish?s face and head is the stuff of nightmares, but don?t worry, despite their large mouths, they only feed on tiny zooplankton. Their elongated snout, known as a rostrum, can detect weak electrical fields, aiding them in their search for food. The American paddlefish is one of the largest freshwater fish in North America, capable of reaching five feet in length and weigh over 100 pounds. Found in many river systems across central U.S., the paddlefish is unique for gamefish as they are not taken by conventional rod-and-reel approach. Instead, bowfishing, spear, and snagging are the primary ways to catch a paddlefish.
