Iceland's whaling season began on Tuesday in defiance of protests from animal rights group that have called for an end to the practice and after international calls for it to reduce whaling quotas.

Iceland, one of two countries worldwide that still authorises commercial whaling, has set a maximum quota of 100 minke whales that can be killed during the whaling season, which usually runs from May to late September.

"We hope to catch the first minke whale today," Gudmundur Haraldsson, one of the whalers on board the Johanna AR vessel, said.

The first whales are usually killed in a bay just outside of Reykjavik as whaling is banned close to the harbour. The restrictions are to protect the whale watching businesses, which are popular with tourists.

"The first batch of meat will be in stores by the weekend," Gunnar Bergmann Jonsson, manager of the minke whaler association, remarked.

He said 50 to 60 per cent of the meat will be sold domestically, while the rest is sold to Japan.

Meanwhile, the International Fund for Animal Welfare led calls for the country to call off the hunting season by handing in a letter of protest at the Icelandic embassy in London.

Former fisheries minister Steingrimur Sigfusson said in February Iceland would make no changes to its whaling quotas of 150 fin whales and up to 150 minke whales per year, despite international calls for it to reconsider.

Prior to Mr Sigfusson's announcement, Iceland, which pulled out of an international whaling moratorium in 2006 after 16 years, had a quota of just nine fin whales and 40 minke whales per year.

Iceland and Norway are the only two countries in the world that authorise commercial whaling. Japan officially hunts whales for scientific purposes, which are contested by opponents, and the whale meat is sold for consumption.
