Marine habitats and the fisheries they support may be modified through the use of human-made physical structures placed in the sea. These structures ('artificial reefs') serve a variety of functions, ranging from the traditional practice of food production to newer applications which include mariculture, tourism and resource conservation. The presentation...
Fisheries exploited under open-access conditions create externalities, resulting in a range of problems associated with over-capitalisation and stock depletion. One answer to this is to shift the mode of production away from hunting and towards husbandry, an approach which becomes feasible where some control can be exercised over the resource...
Aquaculture worldwide has grown rapidly, and while this has brought socio-economic benefits to particular regions there is persistent concern over its environmental impact and sustainability. Within Europe there are quite marked regional variations in the intensity of marine aquaculture, and the fact that this occurs in areas where there is...
It is widely accepted that in sea bottom areas where there is a scarcity of rocky formations and declining marine fish due to fisheries pressure, the deployment of artificial reefs (ARs) is a possible way to mitigate the problem. If ARs have an ecosystem-based fisheries management goal that means their...
In southeast Portugal, some coastal fishing communities have experienced intensified competition for harvestable stocks, and this impacted with some severity on small-scale fishermen who are especially dependent on fishing for their livelihoods. In the last decade or so, various "structural instruments" have been created in order to address this particular...
There has been a growing interest in recent years in the potential use of product differentiation (through eco-type labelling) as a means of promoting and rewarding the sustainable management and exploitation of fish stocks. This interest is marked by the growing literature on the topic, exploring both the concept and...
Economic performance of different fleet segments varies considerably from year to year, with some segments experiencing increased profitability while others experience decreased profitability. This variation is generally considered to be a consequence of the stochasticity in the industry. However, there is growing evidence that fisheries may not be as stochastic...
