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 chums 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.
