The Effect of Aquaculture on World Fish Supplies – 20 Years on
An important review article in Nature, based on data up to 1997 and titled ‘The effect of aquaculture on world fish supplies’, noted that the aquaculture industry was expanding but asked what was its net impact on world fish supplies? Environmental concerns were highlighted (habitat damage, pollution, escapes) and the net contribution of carnivorous farmed species was questioned because of dependence on meal and oil from wild fisheries. This panel will return to these critical issues once again and, with the benefit of hindsight, will make predictions for the future. Has the aquaculture industry responded effectively to environmental concerns? To what extent has it actually been constrained by supplies of fishmeal and fish oil? And finally, what lessons have been learned and what are the implications for policymakers? This same panel discussion was hosted by Seaweb a decade ago but the relevance of the underlying questions endures.
