🥚 Reproduction

Adults home to certain gravelly spawning streams. Two to four males crowd around a female and press against her with their fins. Eggs are scattered and adhere to the gravel or are carried downstream and adhere to the substrate when the water is calmer. The spawning act lasts for 3-4 seconds and may occur 6-40 times an hour . Spent adults return to the lake 10-14 days after spawning began. Most females return to the lake during the first half of the downstream migration followed by most males in the latter half. Downstream fry migration occurs between dusk and dawn .
