A Norwegian Penthrite Granade for Minke Whales: Hunting Trials with Prototypes and Results from the Hunt in 1984,1985 and 1986
A penthrite grenade to replace cold harpoons in the Norwegian minke whale hunt was developed in 1983–1985. Data on survival times for 259 minke whales were collected from the trials in the 1984–86 hunting seasons, when 3 different prototypes were used. About 45% of the whales were killed instantaneo...
