about a crash in whale stocks, as one stock after another was over-exploited. This led to a period of<br />
‘pelagic whaling’, which was conducted wherever whales stocks of harvestable size could be located<br />
(Johnsen 1947).<br />
Economics were then, as today, the main driving force for all whaling activities, other than aboriginal<br />
subsistence whaling. The favoured species at any given time in history, has been determined<br />
according to a delicate balance between, the popularity (<strong>and</strong>, therefore, value) of the material yielded<br />
by the species <strong>and</strong> factors associated with how easy the species was to locate <strong>and</strong> kill. It is important<br />
to note that for the greater part of the history of commercial whaling, oil was the single most<br />
important product. The consumption of whale meat was often a by-product of this industry.<br />
In the late 1930s <strong>and</strong> early 1940s, the International Council for the Exploration of the Sea began to<br />
recognise that the futures of many whale species were not guaranteed, in particular, right <strong>and</strong> gray<br />
whales were in danger of over exploitation, <strong>and</strong> the humpback whale was in danger of extinction. In<br />
1946, the International Convention for the Regulation of Whaling (the ICRW) was agreed <strong>and</strong><br />
created the International Whaling Commission (IWC). This body was charged with regulating<br />
whaling on a multilateral basis for the first time, thus endeavouring to ensure the conservation of<br />
whales.<br />
A brief history of whale killing methods<br />
One of the oldest <strong>and</strong> most widespread methods used for capturing <strong>and</strong> killing whales is called the<br />
harpoon-line-float technique (Mitchell et al. 1986). Harpoons are used to attach a number of lines<br />
<strong>and</strong> floats to a whale, in order to impede its movement through the water. This method is still used<br />
as the primary means for securing, slowing <strong>and</strong> locating whales in a number of Aboriginal<br />
Subsistence Whaling operations (chapter 6).<br />
Before the advent of explosive harpoons, a lance was used as the main method for killing a whale that<br />
had been arrested using the harpoon-line-float technique. However, when larger <strong>and</strong> stronger species,<br />
such as the sperm whale, were hunted, the boat from which the harpoon-line-float method had been<br />
administered was used as an additional anchor. The whale would then have to pull the boat, as well<br />
as the floats <strong>and</strong> line, through the water while attempting to escape. The purpose of this was to<br />
exhaust the animal, which could then be killed using a lance when it was forced to rest at the surface.<br />
In addition, the primitive method of herding smaller cetaceans into bays or onto shallow beaches<br />
where they could then be slaughtered, was popular in Japan, the Faroe Isl<strong>and</strong>s, Orkney <strong>and</strong> Shetl<strong>and</strong>.<br />
This practice may have been common in Japan as far back as the 10th century <strong>and</strong> records of drive<br />
hunts in the Faroe Isl<strong>and</strong>s date back to 1584 (Hoydal 1986).<br />
The first major technological advance in whale killing was the advent of mechanically propelled<br />
harpoons. This enabled the harpoon to cover an increased range, <strong>and</strong> with greater impact than had<br />
previously been possible with h<strong>and</strong> thrown harpoons. Investigations into methods for mechanically<br />
delivering harpoons began in the mid-1700s (Bond 1753). By the second half of the 1800s, a wide<br />
variety of explosive whaling weapons were under trial, many ingenious in design, but often of<br />
questionable efficiency (Mitchell et al. 1986).<br />
A harpoon gun mounted on a swivel was in use from 1731. However, this initial design was hindered<br />
