Dr. Ellen Pikitch:

The are two different menhaden populations - an Atlantic one and a Gulf one - and both are managed within state waters because the bulk of the population is within three miles of the coastline. The species that feed upon them and that are important and of concern also tend to live pretty close to shore. That illustrates that if Ireland has species like the menhaden, although I am not familiar with the Irish species, it can take small-scale, close to shore measures and adopt a policy that would work. In other cases, for example, with Krill in the Antarctic, one could not really do that because Krill is basically the forage species for everything in the Antarctic and the area is huge. One would need a more comprehensive policy for much bigger spatial areas. It is definitely worth looking into the life history and spatial distribution of the fish in Ireland.
