Abstract

From 1985 to 2006, we tracked cui-ui, Chasmistes cujus, survival from potential egg deposition of migrating spawners to emigrating larvae. Tahoe sucker larvae emigrated to Pyramid Lake the same time as cui-ui larvae, but cui-ui was the predominant catostomid larvae we captured. Survival of cui-ui larvae ranged from 0.46% to 21.17%, declining significantly with decreased flow and increased number of spawners (P < 0.01). Mean total length of emigrating larvae ranged from 11.5 to 12.6 mm and may have been affected by stream flow. Removal of impediments to upstream migrating cui-ui spawners, along with sufficient stream flows, may enhance early life-stage survival.
