Everything You Want to Know About the Different Salmon Species
by Garry Gamber
Did you know that there are five species of Pacific salmon and one species
of Atlantic salmon? Further, did you know that all 5 species of Pacific
salmon run wild in Alaska?
We’re proud of our wild salmon here in Alaska, and rightly so. On the one
hand the wild salmon are great sport fish and we Alaskans love to spend
gorgeous summer weekends challenging them.
On the other hand our commercial fisheries are healthy and
self-sustaining. They are able to catch enough wild salmon to satisfy most
of the world wide demand for fresh wild fillets in the restaurants and
packaged wild salmon on grocery store shelves.
King Salmon
The Chinook salmon is nicknamed king salmon in Alaska. It is the official
Alaska state fish.
Description
Of all the Pacific salmon the king is the largest. A 97-pound king was
caught by a sport fisherman in 1986 on the Kenai River. In 1949 a 126
pound king was caught commercially near Petersburg, Alaska. Typically king
salmon weigh 30 pounds and above.
The king is lightly and irregularly spotted on their blue-green back. They
also have a black pigment along their gum line. Spawning kings in fresh
water range in color from red to copper to almost black.
Life Cycle
All species of Pacific salmon hatch in fresh water, spend part of their
life cycle in the ocean, then return to fresh water to spawn.
The king salmon generally live 5 to 7 years, though they can mature by
their second to third year. As a result the kings in a spawning run can
vary greatly in size. A mature 3-year old may only weigh 4 pounds while a
mature 7-year old may exceed 50 pounds.
The young king salmon feed on plankton and insects during their fresh
water period. During their second year they migrate to the ocean where
they grow rapidly.
Some kings make immense spawning migrations. For example, many of the
Yukon River kings will migrate over 2,000 miles during a 60 day period to
reach the streams and headwaters in Yukon Territory, Canada.
Taste
The king salmon has a rich flavor, firm flesh, and a pleasing red color.
Kings caught at the mouth of the Yukon River have a huge store of oil in
their flesh for their long upriver migration. The result is an extra-rich
flavor, much prized among those who love salmon.
Sockeye Salmon
The Sockeye salmon is also called the red salmon due to the bright red
color of its flesh, and it is the second most abundant salmon species in
Alaska.
Description
Sockeye salmon are the slimmest and most streamlined of the 5 species of
Pacific salmon. They differ from kings, silvers, and pink salmon by the
lack of large black spots, and they differ from chum salmon by having more
gill rakers on the first gill.
Sockeye are generally a greenish-blue color with silver sides and a white
or silver belly.
During the spawning season the Sockeye males develop a humped back and a
hooked jaw. Both male and female Sockeye turn brilliant to dark red as
they head upriver to their spawning grounds.
Life Cycle
After hatching during the winter and spending a few months in the river
gravels, the juvenile Sockeye spend 1 to 3 years in freshwater before
migrating to the ocean.
The Sockeye spend 1 to 4 years in the ocean, ranging thousands of miles
while feeding and then returning to the same freshwater system where they
were born. They reach an average size of 4 to 8 pounds, sometimes reaching
in excess of 15 pounds.
Bristol Bay, in southwestern Alaska, annually harvests the largest number
of Sockeye salmon in the world. About 10 million to 30 million Sockeye are
caught during a short season that lasts only a few weeks.
Taste
The Sockeye salmon has an exquisitely rich flavor due to the high
concentration of oils. It is an excellent source of Omega-3 fatty acids.
The rich red flesh color is maintained throughout cooking which results in
a beautiful presentation. Some people consider the Sockeye to be the most
flavorful of all the salmon species.
Silver Salmon
Coho salmon are known as silver salmon in Alaska and are an excellent game
fish.
Description
Coho salmon have bright silver sides and have small black spots on their
back.
Spawning salmon of both sexes develop red to maroon colored sides. The
males develop a hooked snout with large teeth.
Life History
Juvenile silvers live in ponds and lakes formed by rivers and streams.
They generally spend one to three years in the streams and may spend as
many as 5 winters in lakes before migrating to the ocean.
Silvers stay in the ocean, where they grow quickly, for about 18 months
before returning to their home streams. They weigh from 8 to 12 pounds,
but can range up to 31 pounds. Their length ranges from 25 to 35 inches.
Taste
The flesh color of silver salmon is orange-red and is retained during
cooking. The texture is firm and the fat content is high. The taste is a
pleasing full salmon flavor, slightly milder than that of the Sockeye. The
size of a fillet is larger than that of the Sockeye, and it is a prized
fish for cooking.
Pink Salmon
Pink salmon are also known as the humpback in Alaska. Prior to spawning
the pink salmon develops a pronounced hump on its back.
Description
The color of the pink salmon is generally a bright steely blue on top and
silver on the sides. It has many large black spots on its back and over
the entire tail fin. It has small scales and its flesh is pink, befitting
its name.
The spawning pink salmon develops an olive green to black color on its
back with a light-colored to white belly. It develops a very pronounced
hump and hooked jaws.
Life Cycle
The young pink salmon hatch during the winter and spend a few months in
the river gravels. During the spring they migrate downstream to the ocean.
They feed along the beaches before moving out further into the ocean.
Like all salmon, the pinks grow rapidly in the ocean but they are the
smallest of the Pacific salmon species. The pinks reach a size of about 3
to 5 pounds and about 20 to 24 inches in length.
The pink salmon spends only two years in the ocean. This two year pattern
causes distinct odd-year and even-year cycles which are unrelated to each
other.
When the pinks return to freshwater, they are the most abundant of the
Pacific salmon species. They do not migrate far upriver, but generally
spawn within a few miles of the mouth of the river. As with the other
Pacific species both male and female pinks will die within a couple of
weeks of spawning.
Taste
The pink salmon has a delicate, mild flavor and a light flesh color. About
80% of harvested pinks are canned and are the most common salmon species
found on grocery store shelves.
Chum Salmon
Sometimes called “dog salmon” in Alaska, the chum salmon is a traditional
source of dried fish for winter use.
Description
Chum salmon have a metallic greenish-blue back surface with fine black
spots. They resemble sockeye and silver salmon so closely that one needs
to examine their gills and fins closely to make a positive identification.
When nearing fresh water the chum salmon develops noticeable vertical bars
of green and purple, which gives them another nickname, calico salmon.
The spawning chum develop the typical hooked jaws like other Pacific
salmon and large teeth, which partially accounts for their other nickname,
dog salmon.
Life Cycle
As with pink salmon, the young chum do not spend much time in fresh water
before migrating out into the ocean. They feed near the mouths of their
streams for a period before forming schools and moving further out into
the ocean.
The chums spend 3 to 5 years in salt water, growing rapidly after entering
the ocean. They generally range in size from 7 to 18 pounds, sometimes
reaching 30 pounds in weight.
When the chums return to fresh water they often spawn in the same areas as
the pinks, not migrating far up river. One major exception to this pattern
is the chum salmon population of the Yukon River. Some of these chums
migrate 2000 miles upriver to spawn in Yukon Territory of Canada. These
chums have a very high fat content in preparation for their long
migration.
Taste
Chum salmon have a mild, delicate flavor with a medium red flesh color.
However, Yukon River chums, with their higher fat content, have a rich,
full flavor similar to Kings and Sockeye.
Atlantic Salmon
Atlantic salmon are not native to the Pacific coast but are raised in
large numbers in pens. They run wild on the Atlantic coast only. The
Atlantic salmon found in markets are farm-raised, generally originating in
salmon farms off Chile or British Columbia, Canada.
Description
Atlantic salmon in the wild have silvery sides and belly with
greenish-blue coloration on its back.
Spawning Atlantic salmon develop blackish fins and purplish coloration and
reddish spots. Surviving adults are dark in color.
Life Cycle
In the wild young salmon spend one to three years in fresh water before
migrating to the ocean. In the ocean the Atlantic salmon ranges for
thousands of miles.
They generally return to freshwater by the age of five. Unlike the five
Pacific species of salmon, the Atlantic salmon does not die after
spawning. The surviving adults repeat the migration and spawning cycle.
