1. Fish-eating whales are vermin which should be kept to a minimum because they endanger those whose welfare depends on the fishing industry. The worst offender is the minke whale. In the case of Norway, if the stock of sea mammals was reduced to extinction, that country's estimated annual fisheries income would increase from Â£100 million to Â£250 million per year. Employment would increase from 25,200 jobs to 65,500. However, it is recognized that it would not be economic to hunt the whales to extinction because of the cost of locating the last few specimens.
2. In response to criticism that whaling is needlessly cruel the harpoons used were upgraded in 1993 and whalers were required to take shooting courses. As a result it was announced that the average time taken for a whale to die had been significantly reduced, and at 3 minutes 33 seconds this was was 3 minutes less than the average from 1984 to 1986. Of the 226 minke whales taken, half were reported to have died instantly, but 7 lived for more than 20 minutes and one for 55 minutes.
