Abstract

A refuge population of Mohave tui chub (Siphateles bicolor mohavensis) was introduced into Lark Seep at Naval Air Weapons Station (NAWS) China Lake in 1971. As the population branched out into the adjacent channels, habitat maintenance and population monitoring became an ongoing requirement. Periodic population studies were preformed and methods evolved over time based upon lessons learned in the field. Methodological changes included varying the numbers of traps, capturing at different times of year, times of day and with different submersion duration. New populations continue to be discovered. As the population census methodology evolves, more fish are being captured, and the confidence in the population numbers at NAWS China Lake increases.
