Japan could suspend its annual Antarctic whale hunt because the ageing flagship of its fleet needs urgent repair work.
The Fisheries Agency of Japan, which oversees the country's whaling programme, is seeking government funds to carry out extensive repairs and a refit of its main factory processing ship, Japan's Asahi newspaper reported.
The work on the Nisshin Maru could take several months, and the Antarctic whale hunt could not take place without it.
It would be the first time in 25 years that Japan would not engage in the annual whale hunt in the Southern Ocean, which usually begins in November or December.
The 18,000 tonne Nisshin Maru has been on every one of Japan's Antarctic whale hunts which began a quarter of a century ago. Japan says the hunt is carried out for scientific research.
