| Polyodon spathula (Walbaum in Artedi, 1792) |
The Mississippi Paddlefish Polyodon spathula--also called Spoonbill--lives in the slow-flowing waters of the Mississippi River system, feeding on zooplankton by straining them through gill rakers. It may grow to 220 cm and weigh up to 100 kg. Its snout is not only long, but flattened into a paddle shape, thus the name; its purpose is still unclear. Once common throughout the Midwest, overfishing (both the meat and roe are desirable) and river alteration have caused major population declines. Most paddlefish are caught by snagging, since they do not accept bait or lures at all.
Several states, including Missouri, have enacted stocking programs for these fish in reservoirs where the resident populations were low or nonexistent.
