What is whaling? This whaling with the aim of obtaining economic benefits, and not food. To produce in industrial scale and the use of whale meat as food began only in the second half of the twentieth century.

Products of whaling

Today, every schoolchild knows that whaling began with the production of a blubber-whale oil, which was used initially for lighting, in the manufacture of jute, and as lubricants. In Japan, the whale oil was used as insecticide against locusts in the rice fields.

Over time, have changed the technology of melting fat came new materials. Blubber is not used for illumination since then, as there was kerosene, but it is the substance needed for the production of soap. Is it being used as an additive to vegetable fat in the preparation of margarine. Glycerin, oddly enough, is a byproduct of removal of fatty acids from the blubber.

Whale oil used in the manufacture of candles, cosmetics and medical drugs and tools, colored pencils, inks, linoleum, varnish.

Whale meat is meat extract or as bone powder, animal feed. The main consumers of whale meat as food – Japanese.

The Bone powder is still used as fertilizer in agriculture.

In pet foods comes to so-called solution, the broth after meat processing in autoclaves, rich protein products.

The Whale skin in Japan during the second world war, used in the Shoe industry for the manufacture of soles, however, it is not as strong as normal skin.

Blood powder was used due to the high content of nitrogen as fertilizer, and due to the bonding properties – as an adhesive in the woodworking industry.

From the tissues of the whale, get the gelatin from the liver-the vitamin A from the pituitary gland - adrenocorticotropic hormone, from the gut – the ambergris. For a long time in Japan from the pancreas was producing insulin.

Now almost never used whalebone, which at one time was required for the manufacture of corsets, high wigs, crinolines, parasols, kitchen utensils, furniture and many other useful things. Still, there are Handicrafts made from teeth of sperm whale, pilot whale and killer whale.

In a Word, today whales are fully utilized.

History of whaling

The Birthplace of whaling can be considered Norway. Already in the rock paintings of settlements Dating back four thousand years, there are scenes of whale hunting. And from there come the first evidence of a regular whale fishery in Europe between the years 800-1000 ad

In the twelfth century was carried out whaling the Basques in the Bay of Biscay. From there, whaling moved North to Greenland. The Danes and the British hunted whale in Arctic waters. On the East coast of North America, the whalers came in the XVII century. At the beginning of the same century, a similar craft was born in Japan.history of whaling

In those days the fleet was sailing. Whaling sailing ships were small, with a small capacity and not very maneuverable. So hunted bowhead whales and the Biscay with rowing boats, hand harpoons and butchered them right into the sea, taking only blubber and baleen. Apart from the fact that these animals are small, they are still not drowning, being killed, and they can be attached to the boat and towed to shore or ship. Only the Japanese were taken out at sea a flotilla of small boats with nets.

In the eighteenth and nineteenth centuries the geography of whaling grew, captured the South Atlantic, Pacific and Indian oceans, South Africa and the Seychelles.
In the North, the whalers began to hunt bowhead and baleen whales, and later Humpbacks in Greenland, Denisova Strait and near Spitsbergen, in the seas of the Beaufort, Bering and Chukchi.

The time Came when it was invented a new harpoon design which, with minor changes, still exists, and harpoon gun. Around the same time sailing ships gave way to steam, with more speed and maneuverability and is much larger. While I could not change and whaling. 19th century with the development of technology has led to the almost complete extermination of populations of the smooth and bowhead whales, so much so that early in the next century ceased to exist British whaling in the Arctic. The center of the hunting of marine mammals has moved into the Pacific ocean, to Newfoundland and the West coast of Africa.

In the twentieth century whaling had reached the West Antarctic Islands. Large floating factories in sheltered bays, and later the court-of the uterus, with the advent of that whalers no longer depend on the Bank, led to the creation of operating in the high seas fleet. New methods of processing whale oil, which became the raw material in the production of nitroglycerin dynamite, led to the fact that whales have become, among other things, a strategic target of the fishery.

In 1946 established the international whaling Commission, which later became the working body of the International Convention for the regulation of whaling, which was joined by almost all of the country, producing whales.

Since the advent of commercial whaling before world war II, leaders in this area were Norway, UK, Holland, USA. Afterwar, they were replaced by Japan, followed by the Soviet Union.

Harpoons and harpoon guns

Since the mid-nineteenth century to the present day whaling is not without harpoon cannon.

Norwegian whaler Sven Foyn invented the spear new design and gun to him. It was heavy weapons in the 50 kg weight and a length of two meters, spear-grenade, at the end of which are mounted legs, drop-down already in the body of a whale and holding him like an anchor, not allowing me to drown. There was attached a metal box with powder and a glass vial of sulfuric acid, which served as a fuse when broken base reflects the clutches inside of a wounded animal. Later, this vessel was replaced by a remote detonator.Whaling the 19th century

As before, and now the harpoon is made from exceptionally elastic Swedish steel, they do not break even when the most powerful jerks the whale. The harpoon connects with a solid Lin with a length of several hundred meters.

The firing Range of a cannon with a barrel length of about one meter and a diameter of the channel 75-90 mm reached 25 meters. This distance was enough, because usually the ship approached the whale almost came. First, the gun was muzzle-loading, but with the invention of smokeless powder the design has changed, and it began to charge with the breech. By construction, the harpoon gun is no different from ordinary artillery guns with a simple sighting and trigger mechanism, the quality and the effectiveness of shooting as before, and now depend on the skill of the harpooner.

Whaling ship

Since the construction of the first steam to the present, both steam and diesel whaling ships, despite the development of technology, the basic principles have not changed. The usual whaling has a blunt nose and stern, widely collapsed cheekbones, the wheel balancer of the type that provides improved maneuverability, very low side and the high forecastle, speeds speed to 20 knots (land 37 km/h). Power steam or diesel plant is about 5 thousand HP. the Ship is equipped with navigational and search devices.Whaling

The Armament consists of harpoon guns, winches to pull the whale to the side, a compressor to inflate the air in the carcass and ensure its buoyancy, invented Teunom damping system with coil springs and pulleys to prevent the break line during the sharpening jerks of the animal.

Whaling

The Changed conditions for hunting marine mammals, and the seemingly safety of whaling is not needed. But it is not.

Whale Hunting takes place in Northern seas hundreds of miles from the coast or a floating base, often during a storm.

Large powerful speed boats to hunt on large whales. Only to bring to the blue whale, modern whaling ship – already a lot of art. And now, despite the devices search, sitting on the mast in “the crow's nest" of the sentinel, and the harpooner has to guess the direction of a huge animal and to adjust to his speed, standing at the helm. An experienced hunter can operate the vessel so that the head comes up to breathe the whale is near the bow of the ship so close that you can look at the huge blowhole of the animal. At this point, the harpooner transmits the steering wheel and crosses the bridge to the gun. Then he not only monitors the movements of the animal, but also directs the helmsman.

When Keith, zaglotnuv the air, lowers his head under the water, above the surface shows back, at this point, the harpooner shoots and carefully aim. Usually one hit is not enough, Keith vyvazhivaete like a fish, the ship gets closer to him, and follows a new shot.safety of whaling

Carcass of a winch pulled up to the surface through a tube inflated with air and stick a pole with a streamer or buoy, in which is mounted a radio transmitter, cut off the ends of the tail fins, cut on the skin order number and left to drift.

After the hunt, all the drifting carcasses are picked up and towed to the ship-the uterus or coastal station.

Coastal stations

A Coast station are formed around the large slip with powerful winches that raise whale carcasses for dissection, and cutting knives. Both sides are located the boilers: one for rendering the blubber, with another – to handle under pressure from the meat and bones. In drying ovens the bones and meat after rendering fat dried and crushed loops of the heavy chains, which are suspended inside the cylindrical furnace, and then ground into powder in a special mill and packaged in bags. Finished products are kept in warehouses and tanks. At the present shore stations installed vertical autoclave and rotary kiln.modern whaling

Control of the production processes and the analysis of blubber are performed in the chemical laboratory.

Floating factory

In the heyday of the floating factories that now die, they first used a converted large commercial or passenger vessels.

The Carcass was dissected in water, Board up only the fatty layer that were melted on Board, and the carcass was thrown into the sea to be eaten by fish. Coal reserves werecramped, not enough space, so the equipment for manufacture of fertilizers on ships did not put. Carcasses were used irrationally, but the floating mills had several advantages. First, there was no need to rent land under the shore station. Second, the mobility of the factory is allowed to deliver whale oil to its destination on the same ship, not pumping from the shore tanks.

In the twentieth century began to build ocean-going vessels, which are equipped with the latest technology on them to store large supplies of fuel and drinking water. It was the court-of the uterus, which was attributed to fleets of small kilobytes.

Technological process of cutting and processing of fat in such courts, despite the difference in equipment was about the same as at the coastal stations.

Many factories there was equipment for freezing fillet of whale meat is used for food.

Modern whaling expedition

Modern whaling is limited to international agreements about the catch and the duration of the hunting season, which, however, do not all countries.

The whaling expedition included the ship-the uterus and other modern vessels, as well as veterans who engaged in towing carcasses to the floating factories and delivery of food, water and fuel with bases on vessels engaged finding and shooting whales.

There were attempts of searching for whales from the air. A good solution was the use of helicopters that land on the deck of a large vessel, as was done in Japan.

In recent decades, whales have become the focus of public sympathy and attention, and the number of most types because of parapromysly continues to decline. This is despite the fact that almost all kinds of products of whaling, there are already artificial substitutes.

In small quantities continues whaling Norway, in the framework of the aboriginal fishing - Greenland, Iceland, Canada, USA, Grenada, Dominica and Saint Lucia, Indonesia.

Whaling in Japan

In Japan, unlike other countries, ever were engaged in whaling, primarily the prized whale meat, and then the blubber.

The structure of modern Japanese whaling expeditions have always included a separate vessel-the refrigerator in which it is produced is frozen or bought from the whalers of the European countries meat.

Use the harpoons in the hunt for whales the Japanese were by the late nineteenth century, increasing volumes of catch at times, and extending the fishing not only on the sea of Japan, but also in the North-Eastern coast of the Pacific ocean.

Modern whaling in Japan, until recently, was focused mainly in the Antarctic.

Whaling fleet are countries with the largest number of scientific equipment. Sonar will show the distance to China and the direction it is moving. Electric thermometers automatically record the temperature change in the surface layers of water. Using bathythermographs define the characteristics of water masses and vertical distribution of water temperature.

modern whaling in Japan

A number of modern instruments enables the Japanese to justify whaling by the value of the scientific data and mask hunting is prohibited by International whale Commission to the commercial catch of the species.

Many public organizations around the world, especially the USA and Australia, are against Japan to protect endangered rare species of whales.

Australia managed to achieve the decision of the International court banning Japan conduct in the Antarctic whaling.

Hunting of whales, Japan and its banks, explaining the traditions of people of the coastal villages. But the aboriginal fishery is only permitted to the peoples for whom whale meat is one of the main types of food.

Whaling in Russia

Pre-revolutionary Russia was not among the leaders of the whale fishery. Whaling did the Pomors, the inhabitants of the Kola Peninsula and the indigenous population of Chukotka.

Whaling in the USSR for a long time, since 1932, has been concentrated in the far East. First whaling fleet "Aleut" consisted of kitobazy and three whaling ships. After the war in the Pacific were 22 whaling ships and five cutting coastal bases, but in the 60-ies - kitobazy «far East» and «Vladivostok».

In 1947 to the shores of Antarctica came out whaling fleet “Glory”, which was received from Germany for reparations. It was part of processing the mothership and 8 kilobytes.

In the mid-twentieth century in the region began whaling flotilla "Soviet Ukraine» and «Soviet Russia" and a little later than ‘Yuri Dolgorukiy’ with the world's largest floating bases, designed to process up to 75 whales per day.whaling in the USSR

Distant whaling, the Soviet Union ceased in 1987. After the collapse of the Union published data on the violations of the Soviet fleets quotas the IWC.

Today, as part of the aboriginal fishery in the Chukotka Autonomous district is coastal gray whale prey on quotas the IWC and whales under permits issued by the Agency.

Conclusion

whaling in Russian

When a ban was imposed oncommercial fishing began to recover the number of humpback whales and blue whales in some areas of the World ocean.
But populations of baleen whales in the Northern hemisphere are still under threat of extinction. The same concern is bowhead whales of the Okhotsk sea and gray whales in the northwestern Pacific ocean. Too late failed to stop the barbaric destruction of these marine mammals.
