Mouflon scientific literature as separate species, "Ovis musimon" and "Ovis orientalis". The mouflons are also sometimes treated as a subspecies of the domestic sheep, "Ovis aries", named with the same subspecific epithet as above: "O. a. musimon", "O. a. ophion", etc. Based on comparison of mitochondrial cytochrome b gene sequences, three groups of sheep ("Ovis") have been identified: Pachyceriforms of Siberia (snow sheep) and North America (bighorn and Dall sheep), Argaliforms (argali) of Central Asia, and Moufloniforms (urial, mouflon, and domestic sheep) of Eurasia. However, a comparison of the mitochondrial DNA control region (CR) found that two subspecies of urial, "Ovis
Class A Wild Trout Waters Waters vary by species. For brook trout, a biomass of , including at least of brook trout less than long. Additionally, brook trout may not make up less than 75 percent of the total wild trout biomass. The requirements are the same for brown trout except that the minimum brown trout biomass is . For a stream to be Class A Wild Trout Waters for both brook trout and brown trout, the combined biomass of both species must be at least and the biomass of each species must include at least of trout less than long. Neither species may make
