I definitely think, to stay with the insurance policy, it's not a foolproof insurance policy. It depends on the placement of those areas. If they're placed in areas where no cod occurs, of course they have no effect on cod. If they're placed in some of the habitats that cod uses and maybe where some of the spawning happens, the critical habitats where the species aggregates and where all of the life stages occur, it will definitely have a positive effect.
To my knowledge, in Atlantic Canada, the protected area networks that are currently planned do protect some of the important spawning and breeding habitats for cod for that very reason—to avoid another collapse, should it happen. This is definitely a tool that would insure that valuable asset.
