  2. Identification • Laterally compressed • Color – blue/gray to silvery • Incomplete black lines or stripes run horizontally • White belly • Double dorsal fine • Spiny in front, 9 spines • Soft rayed in back • 1-3 pounds

  3. Distribution • Native to the central U.S. west of the Appalachians • Including the Great lakes, Ohio and Mississippi River valleys • Found throughout the state in medium to large rivers • Most of Iowa’s larger lakes and Reservoirs

  4. Habitat • Open water • Often found roaming large open waters in large schools • Ideal temp 65-75 degrees F • Clear water • Firm bottom • Less than 30 feet deep

  5. Diet • Small fish • Gizzard shad • Threadfin shad • Larger insects • Juveniles feed on small invertebrates

  6. Reproduction • Spawn in late April and May • Migrate up tributary streams • Females broadcast eggs in open water • Fertilized by males in the open water • Eggs hatch in two weeks

  7. Conservation Status • Common to Iowa waters • State record 3 pounds 14 ounces from West Okoboji • Population overall is stable • High or no bag limits in most waters • Mississippi River bag limit is 25 per day • No bag limit in other waters of the state

  8. Economic and Recreational Importance • 5th most preferred species among Texas anglers • Popular sport fish in Iowa • Fight hard • Easy to catch • Taste good

  9. Ecological Importance • Important predator • Juveniles are often preyed upon by larger white bass and other predators
