Misspent youth: does catching immature fish affect fisheries sustainability?

Sushi or Fish Fingers? [2ex] How preferences for diversity affect the sustainability of fisheries

Abstract. We consider consumers’ preferences for food fish diversity in a multispecies fishery model. Studying both the long-run equilibria and the transitional dynamics of an open-access fishery we conclude that the outcome is generally less sustainable the stronger preferences for diversity are. We show that even without biological interactions the optimal landing fees for the different stock...

Catching Up on Fisheries Crime

This article describes international collaborative efforts aimed at improving the global capacity to address fisheries crime, with a particular focus on the International Monitoring, Control, and Surveillance (IMCS) network and INTERPOL activities. These 2 initiatives have emerged as a response to existing governance deficits and, combined, substantially improve the prospects for addressing ill...

Biocomplexity and fisheries sustainability.

A classic example of a sustainable fishery is that targeting sockeye salmon in Bristol Bay, Alaska, where record catches have occurred during the last 20 years. The stock complex is an amalgamation of several hundred discrete spawning populations. Structured within lake systems, individual populations display diverse life history characteristics and local adaptations to the variation in spawnin...

Fisheries Management: Sustainability vs. Reality

Sustainability of deep-sea fisheries

As coastal fisheries around the world have collapsed, industrial fishing has spread seaward and deeper in pursuit of the last economically attractive concentrations of fishable biomass. For a seafood-hungry world depending on the oceans’ ecosystem services, it is crucial to know whether deep-sea fisheries can
