ABSTRACT:
Fish production is one of several goods and services that marine ecosystems
provide. Fish have been a major source of protein throughout human history,
but in spite of considerable scientific efforts to understand how changes in
environment and exploitation affect fisheries productivity we have not yet
achieved rational management. Fish populations are affected by climate
variability at all time scales, with major economic and social consequences
for the human communities that depend on them. Other human-induced pressure
include habitat disturbance, pollution, eutrophication and species
introductions. Distinguishing between the effect of these pressures and the
additional effect of anthropogenic climate change is ultimately impossible,
because they interact; the impact of climate on a population depends, among
other things, on its demography, which is affected by fishing mortality.
Since some fish species are more resilient to fishing than others there will
be trade-offs between maintaining biodiversity and maintaining fisheries
yields, but these relationships are also affected by climate. Climate impact
predictions for fisheries are much less reliable than for agricultural
crops, for fairly obvious reasons and some possibilities for improvement
will be discussed. However in spite of the complexity of marine ecosystems
and fish stocks, robust, no-regret management strategies can be implemented
that would sustain yields and help with both adaptation to climate change
and mitigation of GHG emissions.
