Locally, R. osculus, known as the Santa Ana Speckled Dace, can be found in the Santa Ana Watershed drainages, with its nearest neighbor populations inhabiting Owens Valley and Central Coast inland waters. It was attempted to have the dace listed as Federally-Endangered in 1996, but failed due to inadequate evidence that the Santa Ana speckled dace is … Locally, the Santa Ana Speckled Dace is found in such creeks as Lytle Creek, Cajon Creek, Plunge Creek and Mill Creek (Figure 2). �g����]�l���?\�yX�p{�S6 Download Citation | On Jun 1, 2013, John W.

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..

Speckled dace predominantly occupy small streams of the second to third order where they feed and forage for aquatic insects. Loci were screened in 24 individuals from five watersheds. The third goal of this study was to describe the population genetics of R. osculus in Southern California. trout, the Santa Ana sucker and speckled dace, are known to inhabit waters of Lytle Creek, Mill Creek, and the Santa Ana River, and their tributaries. 3]) requires that special measures be adhered to with regard to the capture and clearance of these fishes prior to the diversion and dewatering of the of the active channel, and during any construction within the wetted portions Is a small cyprinid, usually less than 80 mm total length ( Figure,.
