More than five million seals. Thirty pounds of fish per seal per day. Do the
math.

Which fish though? Fish eat fish too. What if seals eat
significant amounts of the fish that eat cod? ....

'culling harp seals in an attempt to reduce the predation
on cod could even backfire. Harp seals eat fish like capelin,
which may themselves eat young cod, he says. So culling
harp seals might even boost the number of cod predators.'
