A risk based approach for promoting management regimes for trawl fisheries in South East Asia
2013
Leadbitter, Duncan
Risk based fishery assessment systems have become more widely developed since their introduction about 5 years ago. Interest has been expressed in applying them in data poor fisheries to help inform management decisions. In the multispecies trawl fisheries in South East Asia, risk based systems may be of great benefit in facilitating the development of management regimes which are urgently needed to improve sustainability. This paper proposes a novel application of an existing risk assessment method for enabling rapid evaluation of different management options. It enables managers and stakeholders to explore options and evaluate which are the most suitable. The risk based system used is the Productivity Susceptibility Analysis (PSA). The trial focuses on the susceptibility axis and explores 12 options for changing the susceptibility of 9 species to benthic trawl gear. The potential for such a system to support management tools such as risk based reference points and harvest control rules is also canvassed.
