Asian halibut is a very unusual kind of beautiful fish, which is also a pretty tasty.It is considered a delicacy, and a dish of it will have to pay a large sum.It lives in the depths of the Pacific or the Atlantic Ocean, so it is rather difficult to obtain.But not only that increases the cost of delicacy.
Build
help to understand the structure of the body, which has an Asian halibut, photos, located in the article.It is elongated, the top is covered with large scales.On both sides of the mouth sharp teeth are arranged in two rows.Lips flat canines are almost closed.This makes the catch halibut hindered.
surprising is the location of the eye.They are located on one side of the animal, which is unique in its kind.Blind part of a different color, it is much lighter.The one where the eye - brownish, sometimes with a touch of blue or black.
In size fish can reach up to one meter, but there are also smaller specimens.Usually in those waters where fishing occurs, it never grows to its maximum size.First, to use an old fish in a food is not as useful and tasty.And secondly, it simply does not have time to grow old, as fishermen carefully monitor the juvenile and sub-adult generation.
Species
Asian halibut strelozuby - one of a kind.But he has an American counterpart.They are distributed on respective sides of the Pacific coast.In fact, they are not much different, and for the most part between observed only similarity.
By flatfish true American, and Asian halibut, the size of each of them reach one meter.Both become sexually mature at about the same age.Males can continue breeding at 6-7 years, females - in 8-9 years.It should be noted that all halibut are predators.
difference is that Asian halibut go to spawn in the fall, the US - in the spring.It is likely that this is due to the temperature regime.Off the coast of America is cooler, so the fry can survive sub-zero winter temperatures.Around Asia, in contrast, warmer.Accordingly, the hot summer weather will not be an opportune time for the growth and development of young fish.
Reproduction
It's hard to find a more individual fish than Asian halibut.Photography can prove it.First, the fish have an asymmetric shape of the skull.Secondly, they can only see one side of the body, since no other eye.However, when it comes to reproduction, from halibut process is more or less standard and usual.
When puberty males and females go to spawn.This occurs in autumn or winter.Then, the first throw eggs at a depth of up to one kilometer.But most of the eggs are found at a distance of 300-500 meters.It is necessary that the water temperature at this time does not fall below 2-10 ° C.
In one approach the female can leave a lot of eggs.Their number reaches 3.5 million.But to survive, of course, can not all.Next the breeding period is terminated, because each berry begins its independent path of development.
birth and development
When it is during the breeding season, the Asian halibut lays eggs that resemble larvae.This is because they have a very large size.In addition, since birth, is still under the eggs, halibut are already able to defend themselves.Over their eyes and are located near the gill cover spines with which they can fight off small predators gathered to eat.
It should be noted that other types of halibut, in addition to Asian and American, no corresponding spikes.
In appearance eggs really resemble larvae.They are thin and slightly elongated.In addition, their color a bit faded.Most likely, this is due to the way of life of fish - it lives at a depth where it is difficult to get sunlight.The eggs may hatch only at 6 degrees for 16 hours.Then they go through several stages of transformation, and in the last stage look like a normal flounder.It occurs in all members of the family do not necessarily halibut.
Develop fry quickly, at the age of three months, they already resemble the structure of the body of an adult.However, age, suitable for reproduction, comes rather late.For this reason, some coast catching fish is considered under supervision.If it does not reside in the territory of the fishery, it can reach the age of 30 years, and only then will die of old age.
Power
Asian halibut - a real predator.Moreover, he will never eat plants or algae.Some fish sometimes make such diversity, but not halibut.
As for food, the halibut in the long run anyway, what to eat.They can eat a small fish, crabs, shrimp and so on.In short, suitable for cooking any meat they believe that only they will meet on the way.
fish halibut prefer pollock or herring, but not against the other representatives of the family of flatfish.Moreover, it is not necessary that the victim was a smaller, more importantly, that she could not fight back.
halibut like invertebrates, in particular - squid.But they may eat them in the summer, when the rise in the upper water layers.
Locations fishing fish are often fed separately.It may be small fish, caught specifically for this purpose, or large individuals, but chopped.
Dimensions
Recently, the question often arises as to which of these representatives will be smaller:
- Orca.
- Asian halibut.
- Seahorse.
Killer whales are the largest representatives of the family of dolphins.Males reach a length of 10 meters, females - 7. Therefore, this option can be folded immediately.
Who are smaller: Asian halibut or sea horse?As mentioned above, flounder grows up to 1 meter, but most often it occurs with a length up to 70 cm. The largest seahorse can reach only 30 cm. Thus, it will be the smallest of the above.
If we consider the representatives from trawl catches, they are usually not more than 50 cm. The small fish in the fishery for release into the wild.Too big, too, as its meat will be not so good and the school as teenagers.
Habitat
fish halibut Asian lives mainly in the North Pacific and the Atlantic Ocean.It can also be found in the Bering Sea, Sea of Okhotsk and the Sea of Japan.In the latter case, the halibut is extremely rare.
sometimes found in Primorye, but in private.There he gets out of the waters of Sakhalin, so no value to the fishery is not.The most widely observed in the North Pacific.Here the fish is found from the coast of Sakhalin Island, and to the western part of Alaska.
Lives halibut at a depth, for this reason, he has a characteristic flat shape of the body.Teenagers who have become full-fledged individuals, but not yet reached the breeding season, try to stay lower than adult specimens.It is likely that this is due to the instinct of self-preservation.Seniors have to go up in order to leave the eggs.
halibut fishery is a valuable commercial species, since it has a good school and fatty meat with excellent taste.Production of fish usually occurs using trawls or longlines.The latter method is rarely used.
appropriate time for fishing is the autumn and winter, as the fish rises above a depth to leave the eggs, to be born and grow offspring.
When trawls gets Asian halibut, its size usually do not exceed 50-70 cm. This is because small fish hiding in the depths, and they do not need to climb higher, because the ability to procreate is not yet developed.
Conclusion
Around Ocean impossible to find a more beautiful, amazing and unique fish than Asian halibut.Pictures decorated with his image a lot of users' desktops, and pictures cause genuine delight.It should also be reminded of the wonderful taste.If you turn up the opportunity to try a dish of this fish, you can not refuse it.And, of course, do not forget about the nutritional value.All the seafood rich in nutrients necessary to human body.But halibut has literally miraculous properties.People feel better after eating his food.
