This is from people who have the local knowledge and a historical context to understand the interactions of seals and fish. We need more science.
Additionally, there are problems now in the north with the ringed seal. The harp seal is a far more aggressive and more competitive seal. They are now showing up in the Davis Strait and in the communities in the north in higher numbers than they ever have before. In fact, they're displacing ringed seals from their breathing holes. Those are the stories we're hearing from the elders and the people on the land.
The interaction of not only the seals with the fish but also the seals with other seal species is quite alarming at this point, from the observations of the people who actually hunt and who live on the land.
