The impact of man on the biosphere is profound. Quite apart from
our capacity to destroy natural ecosystems and to drive species to
extinction, we mould the evolution of the survivors by the
selection pressures we apply to them. This has implications for the
continued health of our natural biological resources and for the
way in which we seek to optimise yield from those resources. Of
these biological resources, fish stocks are particularly important
to mankind as a source of protein. On a global basis, fish stocks
provide the major source of protein for human consumption from
natural ecosystems, amounting to some seventy million tonnes in
1970. Although fisheries management has been extensively developed
over the last century, it has not hitherto considered the
evolutionary consequences of fishing activity. While this omission
may not have been serious in the past, the ever increasing
intensity of exploitation and the deteriorating health of fish
stocks has generated an urgent need for a better understanding of
evolution driven by harvesting and the implications of this for
fish stock management. The foundations for this understanding for
the most part come from recent developments in evolutionary biology
and are not generally available to fisheries scientists. The
purpose of this book is to provide this basis in a form that is
both accessible and relevant to fisheries biology.
