Abstract

Sustainable provision of seafood from wildcapture
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.
