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...
The problem of overexploitation in global fisheries is well-recognized. However, published assessment of fisheries spatio-temporal trends at the national scale is lacking for many high biodiversity developing countries, which is problematic since fisheries management is often implemented at the local or national levels. Here, we present the long-term spatio-temporal trends of Philippine fisheri...

The paper attempts to clarify the research, management and legal implications of a potential application of the Precautionary Principle to capture fisheries, particularly in the international context. In the process, the paper also looks at related issues such as the burden of proof, the use of best available scientific evidence and technology, the reliance on prior scientific consensus, assimi...
Fisheries are subject to a deep-rooted problem of economic inefficiency, often referred to as the fisheries problem. The fisheries problem derives fundamentally from inappropriate social institutions controlling the fishing activity, the foremost of which is the common property arrangement. Fisheries management consists of replacing these institutions with more appropriate ones. Which instituti...
Two mass-balance trophic models are constructed to describe the Gulf of Thailand ecosystem (10–50 m depth): one model pertains to the initial phase of fisheries development, and the other to when the resources were severely depleted. The two phases are compared, and changes brought about by fishing discussed. A dynamic simulation model, Ecosim, is then used successfully to reproduce the 1980 st...
This chapter describes the growth in seafood production and trade and the main factors causing these developments. We then review the leading economic research on the international seafood trade and markets with a focus on interactions of markets and the management of fisheries and aquaculture. Specific examples include the relationship between fisheries management institutions and internationa...
