Whale hunting has been banned since 1986 in order to prevent their extinction. This ban made an exception for indigenous folk, such as Inuit in Greenland and Canada. There is also a clause which allows hunting for scientific study. Despite this ban, Japan, Norway and Iceland have continued to hunt, minke whales in particular, under the guise of scientific research.
All North Sea folk have been involved in the past in whale hunting for either a shorter or longer period of time. In those days, the whale oil was important, which was boiled out of the layer of fat. In order to find the whales, one sailed to the northern Arctic Sea or further. During the eighteenth century, hunting the slower whale species in the north was so intense that these species became too rare and was no longer profitable.
The harpoon canon was founded in the 20th century, which made hunting of the faster fin whales possible. Since then, more than a million blue and fin whales have been reduced into oil and steaks. A new Dutch whaler, the 'Willem Barentsz' was launched in 1950. Fin whales in particular were caught in the south pole region. However, just after several years, the catch was no longer profitable: even in the Antarctic Seas, the number of animals had visibly declined.
Whale hunting was found controversial in the 1970s. The International Whaling Commission (IWC) put an end to commercial whale hunting in 1985. At the end of 1994 in Mexico, the IWC decided to designate a reserve for all whale species near Antarctica. It concerned a permanent and absolute hunting ban for all seas south of 40 degrees latitude. The border is only lower near South America, namely by 60 degrees south.
Whales had never been hunted in the North Sea on a large scale for the simple reason that there were not many large whales here. Porpoises were hunted in Denmark. They would use boats to drive the animals to a sea strait, where they could catch and kill them more readily.
