MARINE PROTECTED AREAS ON THE HIGH SEAS AN INTERNATIONAL SYMPOSIUM HELD AT ZSL ON 3 AND 4 FEBRUARY 2011 ABSTRACTS OF TALKS could be applied to monitor these large pelagic predators. Additional considerations include the lack of baseline data, available resources and the remote nature of Chagos/BIOT. On the 12–13 July 2010 a multi-stakeholder workshop was held at ZSL to address, and prioritise, the future options for management and research in the Chagos/BIOT MPA, however, it was also an opportunity to address monitoring options for pelagic species in the open ocean generally. Expert opinion was gathered in relation to what methods would be available, what time scale they should be used over and how they could work complementarily. After the workshop, more focussed research was carried out in the form of an intra-ZSL meeting on the subject, and a literature search carried out by MSc students. This presentation will review existing and potential methodologies and discuss what might be most appropriate for researching the response of pelagic species to the new MPA. The authors would greatly appreciate comments and input on this review. 16.30–17.30 DISCUSSION LED BY PANEL OF SESSION IV AFTERNOON SPEAKERS 17.30 End of Symposium For further information, please contact: Publications and Meetings, ZSL, Regent’s Park, London NW1 4RY, UK. anne.braae@zsl.org
MARINE PROTECTED AREAS ON THE HIGH SEAS A TWO-DAY INTERNATIONAL SYMPOSIUM HELD AT ZSL ON 3 AND 4 FEBRUARY 2011 POSTER ABSTRACTS MARINE PROTECTED AREAS ON THE HIGH SEAS 3 AND 4 FEBRUARY 2011 — SYMPOSIUM RESEARCH POSTERS PRESENTED Evaluating the effectiveness of MPAs in the open ocean: how do changes in fishing fleet dynamics impact upon conservation objectives? Davies, T. Imperial College London, UK. Email: timothy.davies08@imperial.ac.uk No-take MPAs intentionally exclude fishing activity, causing fleet dynamics to change as fishers inevitably respond to the closure of their fishing grounds. It has been argued that in the open ocean, displacement of fishing effort has the potential to diminish the conservation benefits of MPAs, with fishing pressure continuing to impact upon populations of highly migratory species as they move outside of reserve boundaries. An additional threat is the persistence of illegal fishing within a closed area, which may increase if fishers perceive improved fishing opportunities within an MPA. My research aims to model the response of fishing fleets to a protected area established in an open ocean system, in order to explore the effectiveness of area-based management in conserving highly mobile, pelagic species. Models representing tuna fleets and pelagic species of the Western Indian Ocean will simulate a system that contains a protected area based on the recently established Chagos MPA. In addition to the current MPA fixed area design, a number of alternative reserve configurations will also be evaluated against a set of holistic conservation objectives (rather than narrow objectives related to fisheries management). The principal focus of the project is to construct realistic models of fleet dynamics, which account for the social, cultural, institutional and economic drivers of fisher behaviour, for both the legal and illegal tuna fleets operating in the Western Indian Ocean. This will involve direct interviews with tuna fishermen, analysis of fisheries data and review of historical illegal activity within British Indian Ocean Territory. Models will be used to predict the threat of illegal fishing within the MPA, as well as the impact of effort displacement on populations of highly migratory species. This poster describes my early findings, including a short literature review of the utility of pelagic MPAs based on the Chagos MPA public consultation.

Email: alex.rogers@zoo.ox.ac.uk The ecology of seamounts of the Indian Ocean is almost unstudied. However, exploitation of fisheries resources associated with seamounts in the region has taken place at least since the early 1980s. The South West Indian Ocean Ridge (SWIOR) is a range of seamounts in the high seas that were subject to a major boom-bust fishery for orange roughy in the early 1990s and are still subject to deep-sea bottom fishing. To date the management of the deep-sea For further information, please contact Scientific Publications and Meetings, ZSL, Regent’s Park, London NW1 4RY, UK. anne.braae@zsl.org
