Summary

Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Only sicklefin chub (M. meeki) spawned successfully although sturgeon chub (M. gelida) released unfertilized eggs. All temperature and hormone treatments produced M. meeki spawns, but two treatments had similar success rates at 44 and 43%, consisting of a constant daily temperature with no hormone added, or daily temperature fluctuations with hormone added to the water. Spawns consisted of multiple successful demersal circular swimming spawning embraces interspersed with circular swims without embraces. The most spawns observed for one female was four and [...]
