The Department recently surveyed Roundtree Canyon to monitor the population of Roundtail Chub. The chub were originally stocked in 2008 to establish a new population within the species’ historic range. Three augmentations to the original stocking occurred between 2009 and 2014. Annual monitoring efforts show that the population of chub continues to persist, and has established a recruiting population with the documentation of young-of-year and age-1 individuals. This population will continue to be monitored on an annual basis. The persistence and recruitment in this population is one of the many successful projects the Department is implementing for the ongoing conservation of Roundtail Chub!
