Monitoring would consist of two components: Foskett speckled dace distribution and abundance, and potential adverse changes to Foskett speckled dace habitat due to environmental or anthropogenic factors. Several transplants into parts of California during 1939 and 1940 were considered experiments to test the effects of changed environment on meristic and morphometric characters (Miller 1968). This species was intentionally stocked by Nevada Fish and Game officials in Ruby Marsh-Ruby Lake complex as forage for introduced largemouth bass.

Canada is the northern limit of the speckled dace's distribution, and there it is found only in isolated parts of the Kettle and Granby Rivers. Foskett speckled dace still occurs in portions of the Foskett Spring system. Speckled Dace. It is considered a species complex; some subspecies are protected as endangered (Page and Burr 1991). Distribution. speckled dace reaches the extreme northern limit of its geographic range in southcentral B.C. During breeding, many males often accompany a single female who broadcasts adhesive eggs over the gravelly stream bed. 1982). No long-term studies have been conducted to determine population trends. Speckled dace are the only native fish found in all major drainages in western North America. Hawaii. For these species, some basic information, such as distribution and range, habitat associations, and general abundance, is not known, and it is not possible to determine whether they are truly at risk, or should be designated as a Strategy Species. Formerly threatened by agricultural and residential development. Nonindigenous Aquatic Species Database. It is unclear whether the distribution of the Independence Valley speckled dace has expanded or diminished since the sub-species was listed. Threats: Water development activities (e.g., water diversion, excessive pumping) that eliminated or degraded habitat. The Foskett speckled dace is endemic to a small spring system in the Coleman Basin on the west side of Warner Valley (Lake County) in arid south-central Oregon. It is found as far south as northern Mexico and as far north as south-central British Columbia. Distribution Speckled dace are only found in western portions of the United States and Canada.
