It is considered a species complex; some subspecies are protected as endangered (Page and Burr 1991). In Canada, it is confined to the Kettle River system (Kettle, West Kettle and Granby Rivers), where it occurs along a 275 km length of river.The most recent population estimate from 2010 indicated that approximately 940,000 mature individuals exist in Canada. Analysis of sequence variation in a 670-bp segment of the mitochondrial Names and dates are hyperlinked to their relevant specimen records. When several references are cited, they may give conflicting information on the status. Speckled Dace are known to hybridize with least chubs, Widely used as a baitfish in certain parts of the western United States (Miller 1952; La Rivers 1962; Baxter and Simon 1970). [Updated 22/01/2018] Top 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. The Foskett speckled dace, Rhinichthys osculus subspecies, in Foskett Spring, Warner Basin, Oregon is also protected as threatened subspecies (Ref. Speckled Dace is a small freshwater minnow that resides in the West Kettle, Kettle and Granby rivers within British Columbia, Canada. Established in San Luis Obispo Creek and Webber Lake, California (Moyle 1976a), and in Ruby Marsh, Nevada (La Rivers 1962). The speckled dace (Rhinichthys osculus), also known as the spotted dace and the carpita pinta, is a member of the minnow family.It is found in temperate freshwater in North America, from Sonora, Mexico to British Columbia, Canada.. 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. 5723. This species was intentionally stocked by Nevada Fish and Game officials in Ruby Marsh-Ruby Lake complex as forage for introduced largemouth bass. streams were captured. View Observations. Reported from New Mexico (Sublette et al. The speckled dace (Rhinichthys osculus), also known as the spotted dace and the carpita pinta, is a member of the minnow family. 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. Fish and Wildlife Service officials proposed removing federal protections. 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. The most widely distributed species was speckled dace Rhinichthys osculus (present in 21% of surveyed reaches, excluding dry and nearly dry reaches), followed by bridgelip sucker Catostomus columbianus (19%), Paiute sculpin C ottus beldingi (15%), and redside shiner Richardsonius balteatus (13%). western dace, spring dace, dusky dace, Pacific dace, Moyle (1976a); Wydoski and Whitney (1979); Sublette et al. Table 1. 73: 173-193. Fishes introduced into Willow Creek and the Old Borax Works of California failed to survive; however, the species was common at River Springs, California, in 1967, more than 25 years after its initial introduction (Miller 1968). In the United States, populations occur as far south as California, Arizona and New Mexico. In Canada, the Speckled Dace reaches the northern limit of its distribution, occurring in the Kettle River system (Kettle, West Kettle, and Granby Rivers) in the British Columbia Southern Interior. Unknown in introduced areas. During breeding, many males often accompany a single female who broadcasts adhesive eggs over the gravelly stream bed. 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. 1990). The distribution in this summary table is based on all the information available. 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). Transactions of the American Fisheries Society. Independence Valley speckled dace over the required period (i.e., 3 consecutive years). An 1143 base-pair region of the mitochondrial DNA genome, which included the complete control region was sequenced for all individuals. 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. 1982). Speckled dace are widespread and generally abundant in the Gila River Basin to the north (Minckley 1973). 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). States with nonindigenous occurrences, the earliest and latest observations in each state, and the tally and names of HUCs with observations†. University of Nevada Press, Reno, NV. [2020]. speckled dace is a small cyprinid, usually less than 80 mm total length (Figure 1, appendix A). Canadian populations of the fish were last sampled in 1977, and then only 400 individuals were collected. Contrary to Moyle (1976a), Miller (1968) and Bell (1978) believed that. and J.R. Alcorn. The length-weight relationship for Speckled dace collected in the Kettle- Granby system during July 12 – 21 and August 5 – 8, 2008 (n = 297). Their distribution is largely restricted to the headwaters of the Los Angeles, Santa Ana, and San Gabriel rivers. Formerly threatened by agricultural and residential development. Speckled dace typically inhabit streams containing shallow cobble and gravel riffles, with overhanging riparian plants providing cover for the fish from predators (Moyle, 2002). From 2011 through 2016, the fish's population fluctuated from a low of 1,728 to a high of 24,888. It has adapted to a variety of habitats, ranging from Indeed, the speckled dace is one of the most abundant and wide spread fishes in the western 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. It is believed that spawning in Canada occurs once a year during the summer in fish older than two years. Distribution. Data and Apps Idaho Fish and Wildlife Information System Bringing information to bear on the management and conservation of fish, wildlife, and plants in Idaho. Gainesville, Florida. The Santa Ana speckled dace … The best and most recent information available on the Independence Valley speckled dace population is a report by the U.S. Geological Survey describing results from surveys conducted about ten The list of references for all nonindigenous occurrences of Rhinichthys osculus are found here. 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. In California, their native range includes drainages in Death Valley (Amargosa River), Owens Valley, eastern Distribution trends are not known, but the species’ current range in Canada is likely similar to its modern historic range. 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. Speckled dace are the only native fish found in all major drainages in western North America. Native range data for this species provided in part by. 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. Department of Fisheries and Oceans, Canada, website information on Aquatic Species at Risk. The data represented on this site vary in accuracy, scale, completeness, extent of coverage and origin. Isolation of populations has allowed genetic divergence and resulted in a number of morphologically distinct subspecies. Fishes of the Great Basin: a natural history. 1987). ID: 15531. For queries involving invertebrates, contact Amy Benson. The speckled dace is native to all major western drainages west of the Continental Divide (coastal and interior waters) from Columbia River drainage to Colorado River drainage and south to Sonora, Mexico (Lee et al 1981, Sublette et al 1990). This news builds on other recent successes, including two Oregon fishes that were delisted due to recovery, the Oregon chub and the Modoc sucker. 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. It is found in temperate freshwater in North America, from Sonora, Mexico to British Columbia, Canada. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Threats: Water development activities (e.g., water diversion, excessive pumping) that eliminated or degraded habitat. Few of the fish caught were adults, suggesting that speckled dace mortality may be high. 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.
