The goal of the symposium "Assessment and Management of New and Developed Fisheries in Data-limited Situations," held October 22-25, 2003, in Anchorage, Alaska, was to bring together scientists, fi shery managers, and policy makers to synthesize historical track records, share recent advances, and discuss future avenues for the management of newly developing and small-scale fi sheries under data-limited situations.Expanding worldwide demand for seafood products is not limited to fi shery resources with rich histories of stock assessment and fi shery research. As most of the world's large marine fi sheries are fully exploited or overfi shed, new fi sheries are being developed on marine species whose biology, productivity, and ecological relationships are little known.Data-limited situations create challenges for fi shery managers responding to societal demands to develop new fi sheries while striving for precaution under the Code of Conduct for Responsible Fisheries. This has led to new applications of decades-old simple production models, spawned the development of new assessment techniques with meager data requirements, and led to creative fi shery management schemes, including adaptive approaches, risk-averse methods such as establishment of no-fi shing refugia, comanagement to share responsibilities among vested parties, and rights-based management systems.
