Whaling is the hunting and killing of whales. Historically, poor conservation management by many nations led to far more whales being killed than could be sustained and to near extinction of several species. Whales are killed by firing a harpoon near the head of the animal. An explosive charge inside the harpoon then explodes beneath the whale's skin, killing it.
International cooperation on whaling regulation started in 1931 and a number of bi- and multi-lateral agreements exist in this area, the International Convention for the Regulation of Whaling (ICRW) of 1946 being the most important. The International Whaling Commission (IWC) was founded by the ICRW for the purpose of giving management advice to the member nations on the basis of the work of the Scientific Committee.
The members of the IWC voted in 1982 to enter into a moratorium on all commercial whaling beginning in the 1985-86 season. Since 1992, the IWC Scientific Committee has requested the IWC that it be allowed to give quota proposals for some whale stocks, but this has so far been refused by the IWC. Norway legitimately continues it hunt Minke Whales commercially, as it lodged an objection to the moratorium
Main article: History of whaling
Man has hunted whales since time immemorial. The oldest records of whale hunts are rock cravings found in South Korea that date back to 6000 BC. Since that time the technological sophistication of whalers has grown ever more sophisticated. It is natural to divide historical whaling into four overlapping eras and geographical locations.
The Basque fishery : Hunting in the North Atlantic by Europeans ; the Atlantic Northern Right Whale was a major target. (1400-1700) The Atlantic Arctic fishery : Hunting moves north to around Spitzbergen, Greenland and in between. (1600-1900) The Pacific fishery : American whalers move into Pacific ; targeting the Pacific Northern Right Whale. (1800-) The Sperm Whale fishery : As "fast fishing" techniques improve in the eighteenth century American whalers learn that the Sperm Whale contains valuable oil and exploit it around the world. The rorqual fishery : In the late nineteenth century the explosive harpoon is used for the first time and is devastingly effective in enabling the whaling of the very large rorquals in significant numbers. Species are hunted in all oceans by British, American, Japanese, Icelandic and Norwegian whalers amongst others. Huge "factory ships" which carried out the processing of the meat whilst still at sea enabled whalers to stay at sea for months on end. Population numbers fell by 80-90% across the major rorqual species. By 1946 the international community decided that the destruction should not go on and the newly-founded United Nations passed the International Convention for the Regulation of Whaling. More and more species became protected from commercial hunting in the 1960s and 70s. In 1982 the International Whaling Commission members agreed a general moratorium of commercial whaling that was implemented in 1986.

Although whale oil has little commercial value today, whale meat has come to be considered a delicacy, particularly in Japan. The primary species hunted today is the Minke Whale, the smallest of the baleen whales. Recent scientific surveys estimate a population of 180,000 in the central and North East Atlantic and 700,000 around Antarctica.
