The Challenge of Change:
Managing for Sustainability of Oceanic Top Predator Species

A National Science Foundation (NSF) – Community Building Workshop
Marine Science Institute – University of California, Santa Barbara
April 12-14, 2007

GLOBEC-CLIOTOP Working Group 5 (WG5)
Socioeconomic Aspects and Management Strategies announces a workshop on The Challenge of Change: Managing for Sustainability of Oceanic Top Predator Species. The purpose of the workshop is to foster the development of a research community capable of addressing the many sources of change and uncertainty affecting the international management of marine top predator species.

Oceanic top predators, such as tuna, sharks and billfish, have been intensively harvested by competitive fisheries.   This has resulted in population declines, damage to by-catch species and associated impacts on ocean ecosystems.  The management of these highly migratory species is complicated by the fact that migratory patterns, recruitment, prey availability and other population dynamics are sensitive to imperfectly predictable climate variability and change.

The CLIOTOP (Climate Impacts on Oceanic Top Predators) project aims to contribute to sustainable management of these species.  CLIOTOP identifies and models the key processes involved in the dynamics of open ocean ecosystems in a context of both climate variability and change and intensive harvesting of top predators.  WG 5 seeks to foster research on policy development and implementation under these dynamic circumstances.

Workshop Program:

The workshop will lay the foundation for a comprehensive research program focusing on management of oceanic top predators in the context of change by bringing together leading researchers in relevant areas of fishery policy and science. The program will include a series of keynote talks, panels, breakout discussions and a poster session. See schedule for details.
