Evaluating possible indicators of insensibility and death in cetacea
Contributor(s):: Butterworth, A., Sadler, L., Knowles, T. G., Kestin, S. C.
The International Whaling Commission (IWC) currently uses imprecise indicators of death to evaluate the welfare consequences of whaling. A recent independent meeting of animal welfare scientists proposed a series of tests to determine the states of sensibility/insensibility/death of whales. As a...
Immediate immobilisation of a Minke whale using a grenade harpoon requires striking a restricted target area
Contributor(s):: Knowles, T. G., Butterworth, A.
Approximately 1500 Minke whales are killed annually under permit from the International Whaling Commission (IWC). This hunt supports a modest industry in Norway and in Japan; however, the welfare of whales during hunting and killing is such a cause of concern that in 1980 the IWC formed a...

The effects of education programmes on Atlantic bottlenose dolphin ( Tursiops truncatus ) behaviour
Contributor(s):: Miller, L. J., Mellen, J., Greer, T., Kuczaj, S. A., II
Atlantic bottlenose dolphins (Tursiops truncatus) are found in zoos and aquaria throughout the world. As the number of facilities with dolphin shows and interaction programmes increases, it becomes more important to understand the effects of such programmes on dolphin behaviour. The present study...
