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. 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. It is unclear whether the distribution of the Independence Valley speckled dace has expanded or diminished since the sub-species was listed. Established in San Luis Obispo Creek and Webber Lake, California (Moyle 1976a), and in Ruby Marsh, Nevada (La Rivers 1962). Throughout its broad distribution the speckled dace occurs as hundreds of divergent populations, many of which have been named as subspecies. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report.

Speckled dace from the Virgin River (Utah, Arizona, and Nevada) preferred an average temperature of 15.8 C (range 9.5 to 16 C, depending on acclimation temperature) (Deacon et al. This news builds on other recent successes, including two Oregon fishes that were delisted due to recovery, the Oregon chub and the Modoc sucker. Each point represents a … 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). 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. 5723. This page was last edited on 28 November 2020, at 20:44. Native range data for this species provided in part by NatureServe. The introduced fishes of Nevada, with a history of their introduction.

Hawaii. 1987. The first goal was to characterize the molecular structure of the mtDNA control region of R. osculus. View Observations. Miller, R.R. Speckled dace typically inhabit streams containing shallow cobble and gravel riffles, with overhanging riparian plants providing cover for the fish from predators (Moyle, 2002). Prior to listing, the population was estimated to be 1,500 to 2,000. When several references are cited, they may give conflicting information on the status. Speckled dace were collected at current speeds averaging 0.43 m/sec (SD = 0.25 m/sec, range 0 to 1 m/sec) and at depths averaging 48 cm (SD = 43 cm). 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. It is considered a species complex; some subspecies are protected as endangered (Page and Burr 1991). Reported from New Mexico (Sublette et al. In Canada, the speckled dace is threatened by its limited habitat and by seasonal flooding. Fish and Wildlife Service officials proposed removing federal protections. This species was intentionally stocked by Nevada Fish and Game officials in Ruby Marsh-Ruby Lake complex as forage for introduced largemouth bass. The data represented on this site vary in accuracy, scale, completeness, extent of coverage and origin.

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). Threats: Water development activities (e.g., water diversion, excessive pumping) that eliminated or degraded habitat. Table 1. The small (51 to 94 millimetres (mm)) fish is characterized by an elongated body, prominent snout and sucker-like mouth. TTT . Mouth inferior, sucker-like, lower jaw with fleshy lip. Isolation of populations has allowed genetic divergence and resulted in a number of morphologically distinct subspecies. However, not enough data is available to determine accurately whether the population is self-sustaining or in decline. The list of references for all nonindigenous occurrences of Rhinichthys osculus are found here. Fishes of the Great Basin: a natural history. Sigler, W.F., and J.W.

Distribution data for the Speckled Dace (Rhinichthys osculus) During breeding, many males often accompany a single female who broadcasts adhesive eggs over the gravelly stream bed. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. 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. 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). The length-weight relationship for Speckled dace collected in the Kettle- Granby system during July 12 – 21 and August 5 – 8, 2008 (n = 297). Each female produces between 200 and 500 eggs. The distribution in this summary table is based on all the information available. 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). 1982).

Title: Microsoft Word - VolII K OS e Foskett Speckled Dace Author: thompsc Created Date: 8/10/2006 3:05:19 PM 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 86798). 1990). In 2018, U.S. Speckled Dace (SPD), Rhinichthys osculus, (Cypriniformes: Cyprinidae) has a broad distribution in western North America, being found in all major drainage basins west of the continental divide (Miller and Miller 1948). Speckled Dace is a small freshwater minnow that resides in the West Kettle, Kettle and Granby rivers within British Columbia, Canada. The range of speckled dace is restricted to western North America (Fig. The Speckled Dace is restricted to western North America. 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. The Foskett speckled dace, Rhinichthys osculus subspecies, in Foskett Spring, Warner Basin, Oregon is also protected as threatened subspecies (Ref. The sampling areas are also not within the distribution range of Nooksack Dace, but the permit is being sought as a precaution as the area is accessible to them. This information is preliminary or provisional and is subject to revision. Head bluntly triangular, a small but distinct hump present behind the head. speckled dace is a small cyprinid, usually less than 80 mm total length (Figure 1, appendix A). 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 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. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Analysis of sequence variation in a 670-bp segment of the mitochondrial The Nonindigenous Occurrences section of the NAS species profiles has a new structure. It is believed that spawning in Canada occurs once a year during the summer in fish older than two years. Few of the fish caught were adults, suggesting that speckled dace mortality may be high. Independence Valley speckled dace over the required period (i.e., 3 consecutive years). Although Miller (1968) reported on its occurrence in the Santa Clara River system, California, Bell (1978) did not collect the species there. [Updated 22/01/2018] Top It has adapted to a variety of habitats, ranging from The draft PDM plan proposes to monitor Foskett speckled dace populations following the same sampling protocol used by the ODFW prior to delisting. Of some importance as forage species and widely used as bait fish. Distribution: The ability of speckled dace to colonize new areas and adapt to different environments has resulted in their wide distribution. Figure 2. † Populations may not be currently present. Speckled dace are omnivorous, feeding upon filamentous algae and other plant material, bottom-dwelling aquatic insects and zooplankton. ), the speckled dace was one of the first fish to recolonize the rivers of British Columbia following the Ice Age. The speckled dace (Rhinichthys osculus), also known as the spotted dace and the carpita pinta, is a member of the minnow family. 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). Guam Saipan. Unknown in introduced areas. Native range data for this species provided in part by. Virgin Islands. 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. speckled dace populations in Amargosa Canyon and Owens Valley, California. 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 (1990); Page and Burr (1991); Bond (1994). . Indeed, the speckled dace is one of the most abundant and wide spread fishes in the western Gilbert (1998) recognized 15 subspecies. Distribution.
