I actually took part in the seal ZAP, as it was called, the zonal advisory process on grey seals. We were not able to determine that grey seals were having a significant impact on any fishery off coastal Nova Scotia. It's highly speculative that it has an impact on the southern gulf cod population, so where and when you would have to control seals to allow for recovery of southern gulf cod is still a highly complex question, and it wouldn't necessarily impact any MPA.
