Flatfish
are an order or bony, bottom-dwelling fish. There are more than 400
different species of flatfish, including flounder, sole and halibut.
They are known as “side-swimmers” because they typically
swim along the ocean floor with either their left or right side facing
upward. Many species have both eyes on one side of their head. They
are not born that way, one eye will actually migrate during development.
When a halibut is born it has eyes on either side of its head and
swims upright, like a trout or salmon. Within a year, one of its eyes
moves toward the other side of the head. During the same period of
time, the side of the head with the static eye develops dark skin
pigment, and the bottom side remains white. Thus, the halibut is camouflaged
from above and below.
Halibut live in the Atlantic and Pacific oceans and are the largest
of the flatfish. Feeding on a diet of practically anything they can
swallow, halibut grow to more than eight feet long and can weigh upwards
of 800 pounds. Because of their immense size and voracious appetite,
they have few natural predators. However, most do not get that big and
are slow to develop.
Halibut are one of the most popular and versatile food fish in the
world. Their flesh is snow-white and known for its subtle, sweet flavor.
Halibut meat contains very few bones and large, firm flakes. Fresh halibut
are commonly grilled, broiled or battered and deep-fried. Because they
need little seasoning and feature such a dense texture, they do not
make good fish for smoking. Halibut have been an important source of
food for native North-Americans for more than a thousand years. Over-fishing
of Atlantic halibut decreased the population to an alarmingly low level.
Virtually all halibut on the market today are of the Pacific variety.
In the North Pacific, commercial halibut fishing has been en vogue
for more than a hundred years. Fish are caught using the long-line technique,
which features several baited circle hooks along a weighted line on
the ocean floor. It continues to be a lucrative, large-scale business
because of management by the International Pacific Halibut Commission
(IPHC). Pacific Halibut inhabit waters that belong to the United States,
Canada, Russia and even Japan, where they are known as Hirame. Hence,
proper management is necessary, not only to maintain a healthy fish
population, but to uphold amicable international relations. Halibut
do not reproduce until they are around eight years old. By age eight
an average fish will be a little more than 30 inches in length. International
restrictions prohibit the capture of fish shorter than 30 inches.
Halibut are also a popular sport fish throughout the North Pacific.
Fishermen must use enormous rods and reels equipped with heavy duty
line to haul these monsters in. Because of their incredible strength,
it is common practice to shoot or bludgeon a large halibut before it
is brought on deck. Sport fishing is an important part of Alaska and
British Columbia’s summertime economy. Unfortunately, tourists
reel in a significant number of halibut, many of which are less than
30 inches in length. American and Canadian government agencies have
recently been considering a moratorium on halibut sport fishing.
