The Arctic Grayling (Thymallus arcticus) is one of the most beautiful freshwater fishes. Its most striking physical features are the large, sail-like dorsal (back) fin and colorful body markings. There are six grayling species in the northern hemisphere, but the Arctic Grayling is the only species found in North America. The only populations native to the lower 48 states were in Michigan and Montana, and the Michigan population is now extinct. In Alaska, grayling have the largest natural range of any sport fish, occupying nearly the whole state. Today in Montana, Arctic Grayling are found primarily small, cold, clear lakes with tributaries suitable for spawning. They do not coexist well with other fishes except cutthroat trout and others with which they evolved.
The Arctic Grayling comes in a wide array of colors. Coloration can vary from stream to stream. Their dorsal fins are typically fringed in red and dotted with large iridescent red, aqua, or purple spots and markings. These colorful markings are most dramatic on large grayling. 📸 : Andrew Gilham/USFWS
W A S H I N G T O N : ___________ R E D B A N D ***** Redband Trout are subspecies of the rainbow trout, and exist in two well-defined geographic regions. The Columbia River Redband Trout is found in Montana, Washington and Idaho, and the Great Basin Redband Trout is found in southeastern Oregon and parts of California and Nevada. The Redband Trout is similar in appearance to the rainbow trout, but has larger, more rounded spots and parr marks that remain into adulthood. They generally grow larger than 10 inches. Redband Trout that live in streams tend to have profuse large spots over their bodies and fins (except pectoral) and frequently have an orange cutthroat mark under the jaws. They have a rosy red stripe along lateral line to brick red lateral band (especially in spawning males) and tints of yellow or orange along the ventral region. Gill covers can also be brilliant red. 📸: @seanzenishek
