Live weights of fish produced in three hatcheries of central and northern Indiana were about 75 pounds per acre of largemouth and smallmouth black bass, 105 pounds of spotted or Kentucky bass, and 210 pounds of bluegills and redear sunfish. An experimental pond of year-old bluegills and redear sunfish increased in weight by 366 pounds per acre. The total annual production of warm-water fish for stocking in Indiana is estimated as about 16 tons.
