[Study of the composition of killer whale meat as a source of balanced proteins].

Investigations have shown the proteins of the Orca meat to consist largely of complete water-salt and alkaline-soluble fractions and of an insignificant amount of connective-tissue proteins. The proteins of the Orca meat contain all the amino acids, including essential ones. The lysine and histidine content there in is 1.5 times as high in the proteins of beef. The completeness of the amino acids composition of Orca meat proteins enables it to utilize this raw material for obtaining valuable food products in the form of concentrates or hydrolysates.

Simulations of the effect of currently used grenade harpoons for the killing of whales using a pig-model.

Physical model experiments, as well as simulations of the effects of grenade harpooning on anaesthetized pigs fully immersed in water suggest that the shock effect of the blast from the currently used grenades is relatively minor. 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 shrapnel (fragment scattering) grenades are used instead of blast grenades.
