Abstract

The precautionary principle has become a cornerstone of modern fisheries management and is recognised asbeing of particular importance to the rebuilding of depleted stocks and in cases where fishing activity poses a riskto habitat. Harvest control rules and marine reserves offer two means of controlling fishing mortality, andprovide managers with mechanisms through which precaution can be exercised. We incorporate the two controlmechanisms into a bioeconomic model in which fishing-induced habitat damage occurs. A parameterized modelis used to assess alternative ways of exercising precaution in stock recovery plans in achieving stock rebuilding,while taking into consideration the economic and socio-economic objectives of fisheries management. Resultsstrengthen the case for using marine reserves to rebuild depleted stocks, highlighting their role in providing ahedge against negative habitat-fishery feedbacks by directly protecting biomass and indirectly preventing adecline in the carrying capacity. Overall, we show that where a fishery is characterised by fishing-inducedhabitat damage, a stock rebuilding strategy that incorporates both harvest control rules and marine reserves willoutperform a strategy that uses the two control mechanisms individually, across all performance indicators.
