I am a scientist who has studied marine mammals off eastern Canada for the past 35 years. The concept of a seal cull to improve Maritime groundfish stocks is not scientifically defensible. It is simply not known whether seals have a positive or negative effect on groundfish populations. A large cull of grey seals in the Maritimes will not help our understanding. Removing native species is scientifically indefensible, and, from my perspective, morally wrong.
