Abstract

I present a brief summary of activities for this year associated with native aquatic species in the Bonneville Basin. The June Sucker, Chasmistes liorus, Recovery Program continues to be very active. Approximately 50,000 (200 mm TL) June sucker were reintroduced into Utah Lake as part of recovery efforts. June sucker are propagated from brood stock held at Utah Division of Wildlife Resources hatchery facility at the Fisheries Experiment Station (FES), Logan, Utah. Thirty-three thousand were reared at FES and the remaining 17,000 were reared in grow out ponds. Record numbers of June sucker are returning to the Utah Lake tributaries to spawn. Least chub, Iotichthys phlegethontis, has been petitioned to list and is undergoing a 12-month status review. Refuge populations are exhibiting stable population trends and successful recruitment. Utah, Wyoming, Nevada, and Idaho State and Federal agencies form the rangewide team for the northern leatherside chub, Lepidomeda copei. The Northern Leatherside Chub Conservation Agreement and Strategy was finalized during the past year. The northern leatherside was also petitioned to list this year and is undergoing a 12-month status review. The southern leatherside chub, Lepidomeda aliciae team is finalizing the Southern Leatherside Chub Conservation Agreement and Strategy supported by signatory agencies solely in Utah and will be finalized during 2009.
