Robyn Thorson, the Service's pacific region director, said in a statement; "We attribute this impressive accomplishment to our partners who have worked so hard on the recovery of the dace. Distribution and Habitat: Generally, speckled dace occur in a wide variety of habitats, ranging from cold streams and rivers with rocky substrates to small thermal springs with silt substrates. Unlike other speckled dace, which usually prefer running water, the Amargosa Canyon dace prefers pool-like habitat with deep (0.45-0.75 m), slow ( Distribution: This population is confined to the Amargosa River in Amargosa Canyon and tributaries to it, especially Willow Creek and Willow Creek Reservoir (Williams et al.

Formerly threatened by agricultural and residential development. Speckled Dace. The Foskett speckled dace, found in "harsh conditions" of the desert waters of the Great Basin spanning parts of Southeastern Oregon and Nevada, has been listed as threatened under the Endangered Species Act since 1985. View Observations. Speckled dace are widespread and generally abundant in the Gila River Basin to the north (Minckley 1973). Few of the fish caught were adults, suggesting that speckled dace mortality may be high. Foskett speckled dace still occurs in portions of the Foskett Spring system. The first goal was to characterize the molecular structure of the mtDNA control region of R. osculus. In the United States, populations occur as far south as California, Arizona and New Mexico. desert dace are most often found in habitats lacking otherfish species, they are not confined to them and have been observed coexisting with tni chnb, speckled dace (R. osculus), and Tahoe suckers (Catostornus taltoemis; LaRivers 1962, Nyquist 1963, Siglerand Sigler 1987). 1982).

It is unclear whether the distribution of the Independence Valley speckled dace has expanded or diminished since the sub-species was listed. The speckled dace is about 4 to 5 inches (10 to 13 cm) long. Nonindigenous Aquatic Species Database. Speckled dace are the only native fish found in all major drainages in western North America. ID: 15531. Distribution Speckled dace are only found in western portions of the United States and Canada. These areas are, and will increasingly become, prone to catastrophic fire. During breeding, many males often accompany a single female who broadcasts adhesive eggs over the gravelly stream bed. Speckled Dace . western dace, spring dace, dusky dace, Pacific dace, Moyle (1976a); Wydoski and Whitney (1979); Sublette et al. For queries involving invertebrates, contact Amy Benson. This page was last edited on 28 November 2020, at 20:44. Threats: Water development activities (e.g., water diversion, excessive pumping) that eliminated or degraded habitat. Table 1. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables. In Canada, they reach the northern limit of their distribution and are confined to the Kettle River system (Kettle, West Kettle, and Granby rivers) of south 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. ), the speckled dace was one of the first fish to recolonize the rivers of British Columbia following the Ice Age. The purpose of this genetic study of the Santa Ana Speckled Dace Rhinichthys osculus was three-fold. Distribution and Habitat: The Ash Meadows Speckled Dace is a non-migratory fish which typically lives in warm springs and their outflows. Each female produces between 200 and 500 eggs. In California, their native range includes drainages in Death Valley (Amargosa River), Owens Valley, eastern From 2011 through 2016, the fish's population fluctuated from a low of 1,728 to a high of 24,888. Contrary to Moyle (1976a), Miller (1968) and Bell (1978) believed that. No long-term studies have been conducted to determine population trends. Their distribution is largely restricted to the headwaters of the Los Angeles, Santa Ana, and San Gabriel rivers. Distribution: The ability of speckled dace to colonize new areas and adapt to different environments has resulted in their wide distribution. We examined genetic diversity within- and among-populations of speckled dace (Rhinichthys osculus) in five major drainage systems in the state of Oregon in western North America. Sigler, W.F., and J.W. Head bluntly triangular, a small but distinct hump present behind the head. Gainesville, Florida. 2); it is found in Pacific drainages from the Columbia River south to the Colorado River system, and in coastal drainages between the Olympic Peninsula and southern California in a variety of morphological forms (Scott and Crossman 1973, McPhail 2003). 1990). The Nonindigenous Occurrences section of the NAS species profiles has a new structure. Analysis of sequence variation in a 670-bp segment of the mitochondrial 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. Indeed, the speckled dace is one of the most abundant and wide spread fishes in the western Citation information: U.S. Geological Survey. The population and distribution objective, as set out in the Recovery Strategy, is to maintain the current distribution and abundance of Speckled Dace within natural fluctuations.

When several references are cited, they may give conflicting information on the status. For Speckled Dace, the current population estimate of approximately 940,000 adult fish may be low (due to sampling methodology) and its entire distribution may not have been sampled; as well, the estimate is a single one, so a population trend cannot be discerned. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed.
