If I am summarizing correctly, other predators play an important role, and altogether it means that all of the resource in the sea is declining generally, except for lobster and crab.
You are saying that other predators have more effect on the resource than seals have.
There are all sorts of data circulating. We are kind of left to form our own opinion, today.
Would you be able to give us the proportions, based on your most recent measurements?
