Daddy, what was a tuna?

The BBC report on the latest abundant fish to risk extinction - the Bluefish Tuna.

Everyone blames everybody else, nobody listens to the scientists. The countries are all worried about their fishing fleets now, and don't appear to want to consider their fishing fleets of the future (i.e. there won't be any) because they appear to think if they stop fishing no-one else will, so they'll still end up with no fishing fleet but won't have fish in the meantime. "We're friends of the fisherman" they declare, while allowing the fishermen to drive themselves into extinction.
