If you fish the Mississippi, or near it, you have undoubtedly noticed the increase in white pelican numbers. Nowhere is this more evident than lower Pool 13 where an estimated 4,000+ birds spend much of the year and have the only breeding colony on the Upper Mississippi River.
Adult pelicans consume 2.5 to 4 pounds of fish per day (Hall 1925; Anderson 1987). Although they are often said to feed mainly on small schooling fish of little value to humans, such as gizzard shad and rough fish, they are non-selective and will eat fish that are available to them at any given time.
White pelicans do not dive for fish, feeding only as deep as their necks can reach, so the potential impact to game fish populations on the Upper Mississippi River is theoretically high. This is because fish such as largemouth bass, northern pike, crappies, bluegills, pumpkinseeds, and yellow perch spend much of their time in shallow backwater areas where white pelicans often forage. These species are already faced with a reduction in quality overwintering habitat due to siltation of backwaters.
State DNRs on both sides of the river as well as the U.S. Fish and Wildlife Service have been asked if they know the impact on game fish populations and how many pelicans is too many pelicans. They do not have the answer.
That is why our petition exists — to push for RIVER-SPECIFIC research to get answers that can serve as input to a management plan, if needed. State legislators have been engaged and will also be recipients of the formal proposal when it is presented.
