North America is graced with a wide variety of native salmonids, which include trout,
salmon, char, grayling, whitefish and a variety of other fish. Currently
this page contains pictures and information on species from four of the genuses
of salmonids native to North America; Oncorhynchus (Pacific Trout and Salmon), Salmo (Atlantic Trout and Salmon); Salvelinus (Char) from the family Salmonidae and Thymallus (Grayling) from Thymallinae. While my goal is to catch and photograph all
of the species of trout, char and salmon in North America, right now the main focus
of this webpage is on fish from the genus Oncorhynchus, which most commonly occur within the region that I live in and have a very high
degree of diversity and will be covered first. All of the pictures of fish
on these pages were taken by me of fish that I either caught while fly fishing
or observed while in the out doors or elsewhere. For more pictures and information on a specific species on this page click on the
picture of the fish. |

Introduction |
All Pacific Salmon belong to the genus Oncorhynchus, which also includes several species of Pacific Trout. In North America there
are five species of native Pacific Salmon: Chinook, Coho, Chum, Sockeye and
Pink. There is also a sixth species of Pacific Salmon called the Masu or
Cherry Salmon which is only found in Asia. The five species Pacific Salmon
native to North America share several traits in common such as anadromy, semelparity,
and homing behaviors. Anadromy is a behavior that is common in
many salmonids and is a life history pattern where the fish are born in fresh water,
then migrate to sea and return to fresh water to spawn again. These
five species also exhibit semelparity, which is where the fish die after spawning.
Homing describes a trait that is very common in Pacific Salmon, where
the mature adults return to the same stream in which they where born and sometimes
even the same stretch of that stream. Pacific Salmon populations are currently depressed through out much of their native range due to a slough of issues. Four major issues have presented the largest threat to these fish and are: over harvest from commercial and recreational fishing; habitat destruction from logging, alterations to streams, and other issues; dams which block passage for salmon or cause death during downstream migration; and hatchery fish which compete with native salmon for food and also interbreed with native salmon leading to a loss of adaptations to the local environment. Currently there are many conversation efforts under way to protect the Pacific Salmon but many populations have already gone extinct and the future of these fish of much of their native range remains uncertain as some populations continue to decline. |
Rainbow trout or Onchorhynchus mykiss is one of the Pacific Trout that is native to western North America.
Rainbow trout like Pacific Salmon have the ability to migrate between fresh and
salt water and home to their natal stream to spawn again. The anadromous
form of Rainbow trout is commonly called Steelhead and has become a very popular
game fish throughout the Pacific Northwest and other parts of the world where
it has been introduced. Unlike Pacific Salmon, all rainbow trout are iteroparous
meaning that have the ability to spawn more than once. Rainbow
trout are a relatively diverse species and have a number of subspecies including
Coastal Rainbow trout, Columbia Basin Redband, Northern Great Basin Redband
(there are several unique forms of these redbands), McCloud River Redband,
Sheephaven Creek Redband, Eagle Lake Rainbow, California Golden Trout, Little
Kern River Golden Trout, Kern River Rainbow Trout, and several Rainbow like trout
in Mexico. In there Northern Great Basins of Oregon, Nevada and California,
there are seven unique populations of redband trout; Harney-Malheur, Fort
Rock, Upper Klamath Lake, Chewaucan, Goose Lake, Warner Lakes, and Catlow Basins.
These fish are currently all identified as Oncorhynchus mykiss newberrii, but the classification of these unique trout is still a matter of debate.
I have included these trout here as individual populations classified under Oncorhynchus mykiss newberrii. Anadromous Rainbow trout face the same threats as Pacific Salmon, but for
non-anadromous Rainbow trout populations tend to be more threatened by the introduction
of non-native trout. Hatchery strain Rainbow trout tend to be the
greatest threat to many of these subspecies because they have the ability to
interbreed with them and produce hybrids, but non-native cutthroat, brook trout
and brown trout have lead to the decline of many native rainbow trout populations.
Due to the popularity of the Rainbow trout, they have been stocked
widely outside of there native range and can now be found across most of
North America, and parts of Europe, South America, Asia, Africa, and Australia. |
The Cutthroat trout or Onchorhynchus clarki is another one of the Pacific Trout that is native to western North America and
is closely related to Rainbow trout and is also iteroparous. Cutthroat
trout get there name from a marking under their jaw that can be red, yellowish
or orange colored. Fisherman have considered the Cutthroat as poor fighters
in comparison with Rainbow trout for along time. Cutthroat are also
known to more readily accept fisherman's offerings than many other trout as well.
The Cutthroat trout is a diverse species which has four major lineages
of that are believe to have diverged from each other about a million years ago.
These four lines are considered major subspecies of Cutthroat trout and
included the Coastal Cutthroat, Westslope Cutthroat, Yellowstone Cutthroat and
Lahontan Cutthroat. The Yellowstone Cutthroat and Lahontan in turn have
also diverged into other subspecies leading to a total of 14 subspecies of Cutthroat
trout; four major and ten minor ones. The minor subspecies of the
Yellowstone Cutthroat include the: Snake River Fine Spotted Cutthroat, Bonneville
Cutthroat, Colorado River Cutthroat, Greenback Cutthroat, Yellowfin Cutthroat,
and Rio Grande Cutthroat. The minor subspecies of the Lahontan
Cutthroat are the: Humboldt Cutthroat, Whitehorse Basin Cutthroat, Alvord Cutthroat,
and Pauite Cutthroat. Like many other salmonids within their native range, the Cutthroat trout have not faired especially well across their native range with perhaps the biggest threat being non-native trout. Fueled by the Cutthroat's reputation as an unselective and poor fighting trout, other "more desirable" species of trout have long been stocked Cutthroat waters. As it turns out the Cutthroat's popular relative the Rainbow trout has been the greatest threat to their existence although other non-native trout such as the Brown trout and Brook trout have also caused their share of problems. Brook and Brown trout have a tendancy to out-compete Cutthroat within much of their native range because these two trout are fall spawners while Cutthroat spawn in the spring. This leave the Cutthroat's offspring hard pressed to compete with the larger juvenile Brook and Brown that hatch several months earlier than Cutthroat. While Brook and Brown trout are dangerous competitors to Cutthroat, Rainbow trout are a much greater threat due to their ability to interbreed with Cutthroat. This has already left two subspecies of Cutthroat; the Alvord and Yellowfin extinct and has brought a number of the other subspecies dangerously close to extinction. Today we are beginning to learn from our past mistakes and things are starting to improve for the Cutthroat as they are being protected and re-introduced to their native range. |
The genus Salmo is comprised of two species that are found in North America (one
native and one introduced), as well as a number of other species and subspecies
native to Europe, Africa and Asia. All of the fish of this genus are iteroparous
(can spawn more than once). The two of this genus that are found in North
America are the native Atlantic Salmon and non-native Brown Trout. The
original distribution of Atlantic Salmon in North America was form the Housatonic
River in Connecticut to streams flowing into Ungava bay in Canada.
While the Pacific Salmon a currently facing threats to their populations the
Atlantic Salmon populations are in much worst condition. Soon after European
settlers began to colonize the east coast of the North American continent
threats to Atlantic Salmon began to set in and today due to the same problems
that are now affecting populations Pacific Salmon, Atlantic Salmon have gone extinct
in most streams in the eastern United States and are threatened or extinct
in many Canadian streams as well. While the European settlers brought
with them the demise of the Atlantic Salmon they also brought the Brown Trout,
which is thriving in across North America today. This trout which is native
to Europe, Northern Africa and Asia has become a popular game fish across the
world. |
Char or the fish or the genus Salvelinus very closely related to trout and salmon but differ in appearance. While trout
and salmon have black spots on a light background color, char have light colored
spots on a darker background color. In comparison to trout and salmon,
char tend to be more of a cold water fish and have an optimum temperature
range of between 50ºF and 57ºF. In North America there are five species
of char: brook trout, lake trout, bull trout, Dolly Varden and Arctic
char and a number of species of char also occur in Asia and Europe. Three
of these species Bull Trout, Dolly Varden, and Arctic Char overlap in certain
parts of their range and are so similar in appearance that genetic testing has
to be done to tell them apart. |
The fish of the genus Thymallus or grayling are salmonids, but are much more distantly related to trout, salmon
and char and are actually in a separate family Thyamllinae. In North America,
there is only one native species of grayling Arctic grayling. There
are three other species grayling as well found outside of North America, which
include the: Mongolian grayling, European grayling, and Kosogol grayling. |
