I'd think an added pressure on cod created by the seals is the large abundance of cod with parasites in them. My understanding is the parasites are excreted by the seals and head downward. I don't have nearly the experience to state this first hand, but from those I've talked to, this seems to be a source of added stress on bottom fish.
