Just generally, as noted before, the role that seals play in the population of fish is very complex. For example, cod can lay 1 million or 5 million eggs, depending on the size of the female. Obviously there's a high mortality on those individuals at some stage--for instance, they're killed by filter feeders that are in turn eaten by seals. As to how a seal would play a role in that, when we asked an eminent panel of scientists to look at it, they could not come up with advice.
Having said that, they did suggest that there might be something to look at in terms of seal exclusion zones where you have spawning concentrations. We looked at how seal exclusion zones in those areas could be contributing to the rebuilding of stocks. There weren't that many seals in those locations, so it wasn't a big factor.
We do have programs in the case of nuisance seals, or seals that have been targeting particular runs. For example, in the river systems, where seals have been a big factor in mortality, we have in the past taken action in those areas.
