Four of the seven species of fish present in refuge waters are endangered; the other three are introduced exotic species. Ash Meadows pupfish are visible year-round at all the major springs and streams on the refuge, such as Crystal and Longstreet, but are most visible and colorful at Point of Rocks. Male pupfish take on a bluish cast during the spring and summer breeding season, whereas females remain olive green year round. Look for the Ash Meadows speckled dace at Jackrabbit Spring. The endangered dace can grow to almost four inches and may live up to four years. Non-native, introduced species such as largemouth bass, mosquitofish, sailfin mollie, bullfrog, and crayfish are being removed by the U.S. Fish and Wildlife Service, as they are harmful to the native fishes through competition for the same limited resources.
