As. Blix et al., Simulations of the effect of currently used grenade harpoons for the killing of whales using a pig-model, ACT VET SC, 41(3), 2000, pp. 237-242
Physical model experiments, as well as simulations of the effects of grenad
e harpooning on anaesthetized pigs fully immersed in water suggest that the
shock effect of the blast from the currently used grenades is relatively m
inor Also the animals are not stunned to death, but loose consciousness and
subsequently die from hemorrhage. Survival time is therefore very short if
the animals are hit in the thorax, and is likely to be further reduced if
the charge which is currently used is increased, or, even better, if shrapn
el (fragment scattering) grenades are used instead of blast grenades.
