a suitably placed processing plant. This discrepancy between what the
resources deployed in fishing do produce, and what they could produce
will tend to widen as more and more of the world’s accessible stocks of
fish become heavily fished. Without some fundamentally new approach
it is doubtful if the fisheries of the world can maintain their recent
record of increasing production faster than the increase in world
population.
