Gone with the Flow: How a Little Fish Is Emblematic of Big Problems in Great Plains Rivers (by Shannon Brewer in "The Lateral Line" (Volume 35(1) October 2014))

Declines in aquatic habitat quality and quantity have resulted in the imperilment of approximately 40% of North American fish species. This pattern is particularly evident in the Great Plains where a once diverse endemic fish fauna is rapidly disappearing, most notably, in a unique group of minnows collectively referred to as pelagic broadcast-spawning cyprinids. These fishes reproduce via semi-buoyant eggs released directly into the water column. This strategy is rare in freshwater fishes and is thought to be an adaptation to the ‘harsh’ conditions of Great Plains rivers. The drifting eggs are kept safe from shifting sand substrates, but potentially require ....
