Alaskan
Wild Salmon Species
The five
species of Alaska salmon are members of a large family of fish
known as salmonidae which are abundant throughout the temperate
zones of the Northern and Southern Hemispheres. Salmon and their
salmonidae relatives, which include Atlantic salmon, are active
and aggressive predators who demand the high levels of oxygen most
commonly found in cold, rushing streams, estuaries, and the upper
levels of
the
ocean.
Pacific
salmon occur from California north along the Pacific coast
throughout the Pacific Ocean, Bering Sea and Arctic Ocean waters
adjacent to Alaska. Alaska’s wild salmon resource is the greatest
in the world.
Alaska salmon belong to the genus Oncorhynchus, a name formed by
combining two Greek words, “onco” meaning hook or barb, and “rhyno”,
meaning nose. The scientific names for each of the five species were
given during the exploration of Siberia, and reflect the native
vernacular names for the fish. Thus, we have:

Alaska salmon
are anadromous, that is, they spawn in fresh water and the young
migrate to the sea where they mature. The timing of spawning and
migration varies among the five species, but they all need abundant,
pure, fresh water for spawning. The fresh water that attracts the
maturing salmon from the ocean vastness to the interior of the
continent to spawn also draws the salmon to man’s doorstep.
Although the
spawning characteristics of each of the five species of Alaskan
Wild Salmon differ, each maintains the same timing year after
year, and, with few exceptions, the mature adults return to the stream
of their birth.
Salmon which
will spawn in the headwaters of a river or lake system (king, coho and
sockeye), arrive earlier than do the pink and chum which spawn closer
to tidewater. Because salmon do not eat after they have entered fresh
water, they leave the ocean heavy with the fats and nutrients on which
they will subsist during their freshwater phase. The longer and more
rigorous the freshwater trip, the more fat the fish will carry as he
leaves the ocean. A Yukon River king headed for spawning grounds 2,400
miles (4,000 kilometers) away and 2,200 feet (670 meters) above sea
level near Lake Teslin will enter the river an unusually rich,
vigorous fish.
How salmon
return so unerringly from mid-ocean to a stream which may be only a
trickle hundreds of miles from tidewater is not fully understood by
biologists. Except where humans have interfered, however, the salmon
returning to the various river systems and streams of Alaska are
unique species which may mingle in the ocean and even in the estuary,
but return faithfully to the gravel from which they emerged two to six
years earlier. Fish that enter fresh water early in the season are
more brightly colored than those that arrive later, but all salmon
turn darker as the time to spawn approaches. Pronounced morphological
changes take place, particularly in the spawning male. The female
selects a suitable patch of gravel, and excavates the nest. When she
is ready, she allows the male to fertilize her eggs as she deposits
them in the gravel.
Five to seven
months after spawning, the young salmon fry emerge from the gravel
where the spawning pair deposited and fertilized the eggs the fall
before. Some of the fry will go to sea almost immediately, while
others, such as sockeye, king and coho will remain in streams and
lakes for a year or more. When the fry migrate toward the sea, they
undergo certain changes which prepare them for life in salt water;
during this stage of life they are called smolts. In the estuary,
where salt and fresh water mix and food is abundant, a smolt may
double or even triple its weight before venturing westward into the
Gulf of Alaska or Bering Sea. Depending on the species, the salmon may
go within a few miles of the Kamchatka Peninsula which extends
southward from Siberia toward the western tip of the Aleutian Islands.
Growth rates in
the ocean are no less astonishing than those in the estuary. A
two-inch pink salmon which leaves the estuary and moves offshore in
early-to-mid summer can return slightly more than a year later as a
two-foot, five-pound adult. Pink salmon spend a year in ocean waters;
other species may spend four, five or even six years in the ocean
pastures growing to prodigious size. Any "125 pound plus" king salmon landed in
Southeastern Alaska is thought to have spent seven years in the ocean.
The cold, clear waters
off Alaska's 34,000 mile coastline are the world's greatest
resource for natural, wild salmon. There, the five species of
Alaska Salmon mature in an unmatched natural environment that
provides them with superior flavor, color, and texture. This makes
Alaska Salmon the salmon of choice of foodservice operators
throughout the world. Quick frozen within hours of being harvested
at the peak of its lifecycle, Alaska Salmon offers your
foodservice customers these unique advantages:
A NATURAL ADVANTAGE
Alaska Salmon has a
richer color, firmer texture, and better flavor than
industrially-produced salmon. This natural superiority results
from a life spent feeding on the sea's natural foods while
swimming against the strong currents of the cold, clean North
Pacific.
A FRESHER-FROZEN ADVANTAGE
The Alaska seafood
industry has perfected advanced quick-freezing technology which is
unique in its ability to capture the fresh-caught flavor of the
salmon while preserving the fish's firm texture and rich color.
YEAR-ROUND AVAILABILITY
Fresher-frozen natural
Alaska Salmon is available year-round in portion-controlled sizes
in a variety of packaging and product forms. Fresher-frozen
products minimize shrink and keep margins high.
NUTRITIONAL INFORMATION
Natural Alaska Salmon
is an excellent source of high quality protein, and contains
predominantly healthy unsaturated fats.
