Aquatic Inventory of the Upper Bill Williams Drainage, Yavapai and Mohave Counties, Arizona

摘要

The upper Bill Williams drainage in Yavapai and Mohave counties, Arizona supports a diversified fauna of native and introduced fishes. Twenty-two species and two hybrids have been recorded from the upper drainage and Alamo Lake. Museum records were combined with collections from an extensive aquatic survey of the area to outline an account of the fish species that occur there. Patterns of distribution and abundance appear to be relatively stabilized with native fishes.
