Crews pulled hundreds of young silver carp from an Illinois River pool just 80 miles from Lake Michigan; their size points to possible spawning farther north

The fish were only a few inches long, suggesting that reproduction may have occurred farther upstream than previously documented and bringing the invasive species closer to Lake Michigan.
