Alternative bleeding method for the hunt for young grey seals (Halichoerus grypus): common carotid arteries versus axillary arteries

By Daoust, P.-Y., and Sauvé, C.C.

Abstract

In recent years, the hunt for young grey seals (Halichoerus grypus) on the Magdalen Islands, Québec has targeted utilization of the meat rather than that of the pelt. Mandatory bleeding by severance of the axillary arteries and surrounding blood vessels may cause contamination of the meat by debris on the ground where these animals are killed. This study aimed to evaluate an alternative bleeding method based on severance of the common carotid arteries and surrounding blood vessels, which should reduce contamination of the meat normally collected. Bleeding time by severance of the common carotid arteries was overall similar to that by severance of the axillary arteries, and did not vary with sex or body mass. Results demonstrate that the proposed alternative is at least as efficient as severance of the axillary arteries from the perspective of animal welfare and could thus be used during the hunt for young grey seals.
