Exploring Patterns of Seafood Provision Revealed in the Global Ocean Health Index
- 492 Downloads
Sustainable provision of seafood from wild-capture fisheries and mariculture is a fundamental component of healthy marine ecosystems and a major component of the Ocean Health Index. Here we critically review the food provision model of the Ocean Health Index, and explore the implications of knowledge gaps, scale of analysis, choice of reference points, measures of sustainability, and quality of input data. Global patterns for fisheries are positively related to human development and latitude, whereas patterns for mariculture are most closely associated with economic importance of seafood. Sensitivity analyses show that scores are robust to several model assumptions, but highly sensitive to choice of reference points and, for fisheries, extent of time series available to estimate landings. We show how results for sustainable seafood may be interpreted and used, and we evaluate which modifications show the greatest potential for improvements.

Beau and Heather Wrigley provided the founding grant for the original Ocean Health Index work. Additional financial and in-kind support was provided by the Pacific Life Foundation, the Thomas W. Haas Fund, the Oak Foundation, the Akiko Shiraki Dynner Fund, Darden Restaurants Inc. Foundation, Conservation International, New England Aquarium, National Geographic, and the National Center for Ecological Analysis and Synthesis (NCEAS). This is a contribution from the NCEAS Ecosystem Health Working Group and the Sea Around Us project, a collaboration between The University of British Columbia and The Pew Charitable Trusts. We thank A. Tavakolie for assistance with some of the indices. MC was supported by a Marie-Curie CIG Fellowships and a research contract of the Ramon y Cajal program of the Spanish Government.
