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...
The artificial reef of Vilamoura (ARV) deployed between 1998 and 2001 is situated off the fishing community of Quarteira and the tourism resorts of Vilamoura (Southern Portugal). The reef extends for approximately over 4,000 m long and 1,400 m wide at a depth ranging from 20 to 40 m below...
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...
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...
