We study dynamic labour supply using data on paua (abalone) divers in New Zealand. The divers face stable, flat prices per kilogram after each catch, but experience transitory wage changes due to varying weather and water conditions, and are free to vary their daily working hours and display an...

The New Zealand Ministry of Fisheries constrains the incidental capture of Hooker’s sea lions in trawl nets of the southern squid fishery by closing the season once an upper limit on sea lion deaths is reached. The regulatory measure is in fact a limit on effort because the number of sea lion...

Development and societal changes in the twentieth century have transformed the nature of fishing in Fiji. This paper attempts to consolidate a large amount of decentralized work on the development of Fijian fisheries to address the long-term sustainability and economic viability of Fiji's marine...

This paper develops a bioeconomic model that captures the underlying incentives driving the serial depletion of pristine seamounts. The determinants under New Zealand's Quota Management System relate to unit cost savings from bottom trawling for orange roughy on seamounts, where catch rates are...

The New Zealand Ministry of Fisheries constrains the incidental capture of HookerÕs sea lions in trawl nets of the southern squid fishery by closing the season once an upper limit on sea lion deaths is reached. The regulatory measure is in fact a limit on effort since the number of sea lion...

This work expands upon Swallow's theoretical analysis of interactions between renewable and non-renewable resources. In this comment the interaction is such that the renewable resource prefers the non-renewable environment, as opposed to SwallowÕs (op cit) case of the non-renewable environment...

The importance of essential fish habitat in supporting commercial fisheries has received increasing attention in recent years. Bottom trawling is known to cause particularly destructive damage to habitat which is effectively non-renewable, such as cold water corals. This paper applies the...

The paradigm shift to holistic management rests on the insight that exploitation affects all aspects of the ecosystem. While scholars and policy-makers all want ecosystem based management (EBM), few, if any, have achieved it in practice. Adaptive governance promises effective EBM, but guidance...
