Has anyone watched this episode? I thought it was pretty informative the first time I viewed it, but Alan and his team didn't really draw any conclusions other than; the fish are declining rapidly and that there are many factors that contribute to the declining numbers.
He does a good job, however, of exploring how modern science is trying to at least get an understanding of how to best deal with it.
