The Plains Minnow
The Plains Minnow lives in schools, and is found in sand and silt-bottom rivers and streams of the Central Great Plains. Found in a range of small creeks to fairly large rivers, the Plains Minnow prefers slow, relatively shallow to moderately deep waters with a range of turbidity. Many of these small-to-medium-sized streams experience natural seasonal fluctuations, from drought conditions to flash floods and heavy precipitation, indicating a high level of adaptation in withstanding natural changes in water quality. Spawning takes place in areas of moderate flow to maximize the downstream distribution and incubation of the fertilized eggs. The Plains Minnow lives for about two to three years, and breeds for the first time in its second year. Many individuals die after spawning. The Plains Minnow has an extended spawning period, frequently reproducing after major flow peaks. The majority of reproduction takes place in spring; however, it has also been recorded in the summer. Females carry less than 1,000 eggs. Once hatched, growth takes place quickly and juveniles nearly reach their adult size by the end of their first summer.
