Today, essentially all big fish are gone, and rising seal numbers have not nearly made up for the loss. To maintain a healthy natural predator presence in the ocean, therefore, none of the relatively few surviving fish predators should now be killed, and that includes seals.
Natural predators play key roles; and entire ecosystems, including the prey species, do better when predators survive too. Eliminating large predators degrades ecosystems, and this occurs everywhere from forests to grasslands to oceans.
The worst of it is that there are DFO [Department of Fisheries and Oceans - Editor] scientists who are aware of this problem, but who are not permitted to speak openly about it.
