Sustainable fisheries

metals such as copper. Once the manganese protein has folded, the metal-binding sites are inaccessible to other metals, and the protein can be safely exposed to the periplasmic envi­ ronment. In other words, the metal that binds to the protein is selected by the compartment in which the protein folds. Tottey and colleagues suggest that cytoplas­ mic metal insertion might be crucial not only for...

Demographic Diversity and Sustainable Fisheries

Fish species are diverse. For example, some exhibit early maturation while others delay maturation, some adopt semelparous reproductive strategies while others are iteroparous, and some are long-lived and others short-lived. The diversity is likely to have profound effects on fish population dynamics, which in turn has implications for fisheries management. In this study, a simple density-depen...

Irreducible uncertainties, sustainable fisheries and marine reserves

Marine reserves are increasingly proposed as a management tool. Models can play a valuable role in the evaluation of the possible benefits of reserves because they allow us to conduct many more investigations than could ever be done empirically. In this paper, I develop a model for a marine reserve for an open population subject to environmental uncertainty.

Sustainable Fisheries: Addressing a Global Problem

Currently, of the world’s assessed stocks, only 20% are estimated to be moderately exploited or underexploited, 52% are fully exploited, 1% are recovering from depletion, 8% are depleted, and about 19% are considered overexploited (Cochrane et al. 2011, this volume). Fisheries are vitally important renewable resources if they are governed sustainably with responsible harvest from healthy popula...
