A study on the effect of different rifle calibres in euthanisation of grey seals (Halichoerus grypus) in seal traps in the Baltic Sea

摘要

Background In recent years, the euthanasia of seals has been discussed internationally and concern has been raised regarding the use of rifles, the effect of different calibres, and which calibres are sufficient for humane euthanasia. This study therefore investigated the effect of different firearm calibres on euthanasia of grey seals (Halichoerus grypus) in traps, and provides information for the development and refinement of regulations for hunting seals in the wild.
