While the recurrent cost of managing marine protected areas (MPAs) has been documented and estimated, there has been virtually no attempt to quantify the cost of establishing MPAs in the first place. This lack of attention is likely the result of the complexity of the process, involving often...

Time series data was used to compute 5-year moving average rates of growth in salmon aquaculture production over time for four of the world's leading salmon farming countries, and globally. This analysis reveals a decline of 1.2% per year in global farmed salmon production since it peaked in...

We present in this paper results of an analysis of the potential economic contribution of sablefish farming in British Columbia (BC). This is necessary because a BC sablefish hatchery has recently begun production of juvenile sablefish for grow-out in marine net pens. The production from this...

The life spans of demersal species of fishes occurring in deep-waters are much longer and their potential growth rates much lower than those of related shallow water species. As a result, deep-sea demersal fish species are more vulnerable to exploitation. This is because low growth rates...

By comparing the real reductions in fishing capacity of the European Union (EU) and the effects of technological efficiency, this paper presents the first comprehensive analysis since the creation of the Common Fisheries Policy (CFP). Using a standard methodology and a conservative value of...

This paper presents a historical account of Brazilian public policy on fisheries subsidies, and a discussion of problems and limitations resulting from such policy. From the 1960s to the mid-1980s, public policies led to a great increase in fisheries catch without appropriate consideration for...

We estimate the unregulated catch and fisher income of the Kabui Bay migrant anchovy fishery operating in the Raja Ampat regency, Papua, Indonesia. Interviews with migrant fishers were conducted in April and November 2006, and estimates were generated through Monte Carlo simulations. Anchovy...

This study describes variability in the marine ecosystem of Ghana, West Africa, on several temporal and spatial scales and discusses how the human communities using this ecosystem respond to this variability to cope socially and economically. Ghanaian marine waters are part of an upwelling...

We assess, based on fisheries and interview data collected on-site, whether Malthusian overfishing is occurring in Pulau Banggi, Sabah. Fisheries resources in Pulau Banggi have been perceived to be declining over the past 20 years, and characteristics of Malthusian overfishing are evident,...
