Salmonid ID and Species List

Salmonids

The salmonids are in family Salmonidae, which has 10-11 genera divided into 3 subfamilies; Coregoninae(whitefish), Thymallinae(grayling), and Salmoninae(char/trout/salmon). Living in the Southeast you have access to a very limited amount of salmonids and I’ve caught the 3 that occur in Georgia, only 1 actually being native, the brook trout. I made my first trip out West in September of 2012 to Colorado and caught several greenback cutthroat trout in Rocky Mountain National Park – or what were considered greenbacks at the time.  Made another trip out West in August of 2013 to Teton and Yellowstone National Parks where I picked up a couple more cutthroat species.  Finally in August of 2015 I was able to complete the Wyoming Cutt Slam, picking up Wyoming’s four native cutthroat species (they do have a fifth, the Westslope, that is not required for the slam – I’ve yet to catch a Westslope).

Dr. Robert Behnke is the man when it comes to salmonid knowledge. Pick up his book if you want to learn more about this particular family, “Trout and Salmon of North America”. Another great resource is Gary Marston’s Native Trout Fly Fishing blog, he has a Trout and Salmon species page with pictures and information of all those that he has caught (which may be all that are found in the U.S.). Gary’s trip reports are a good read as well, he has had some epic road trips to catch trout in their native range. Another good resource is the Angler’s Life List & Native Fish Network. They have a fish page that illustrates the native ranges of salmonids in Google Maps.

Oncorhynchus mykiss – Rainbow trout

IMGP5637

Salmo trutta – Brown trout

IMGP5730

Brown trout are exotic to North America, so there is no native range map available on NatureServe. This is their distribution map, pink illustrates what states they might be found in (Alabama?).

Salvelinus fontinalis – Brook trout

IMGP5747

Oncorhynchus clarki stomias – Greenback cutthroat trout

IMGP7693

No range map was given from NatureServe for the greenback, but their historical range is pretty much in the state of Colorado on the Front Range, with some watersheds slipping into Wyoming. They are found in the headwaters streams of the South Platte and Arkansas River drainages.

Oncorhynchus clarki pleuriticus – Colorado River cutthroat trout

No range map was given from NatureServe for the Colorado River cuttroat, but their historical range is headwaters streams in the Green and Colorado Rivers, as far south as the San Juan River, west of the Continental Divide.  They are currently limited to a few small headwater streams of the Green and upper Colorado rivers in Colorado, Utah, and Wyoming, including the Escalante River drainage in southern Utah

Oncorhynchus clarkii utah – Bonneville cutthroat trout

No range map was given from NatureServe for the Bonneville, but their historical range is pretty much in the state of Utah, with some watersheds slipping into Wyoming, Idaho, and Nevada. They are found in the headwaters streams of the Bear River.

Oncorhynchus clarkii bouvieri – Yellowstone cutthroat trout

IMG_5982

No range map was given from NatureServe for the Yellowstone cutt, but their historical range is the Yellowstone River drainage in Montana and Wyoming and the Snake River drainage in Wyoming and Idaho.  Their current range overlaps with that of the Finespot in the Snake River drainage above Shoshone Falls.

No range map was given from NatureServe for the Finespotted Snake River cutt, but their historical range overlaps the Yellowstone cutt in the states of Wyoming and Idaho. They are found in the headwaters streams of the Snake River, particularly the South Fork.
