Abstract:: Artificial reefs (AR) were created not only to protect sea bottoms (Lee et al., 2018) and enhance biodiversity namely by stimulating the enhancement of fish stocks (Pioch et al., 2020), but also to attract diving tourism (Shani et al., 2012) or sport fishing enthusiasts (Radonski et al., 2018). In order...

Abstract:: Artificial reefs (AR) were created not only to enhance biodiversity (namely by stimulating the increase of fish stocks), but also to attract diving tourism or sport fishing enthusiasts. Industry 4.0 tools – e.g., mobile technologies and cloud computing – can be used for AR monitoring purposes and can serve as...

Creator:: De Lara, Michel, Ocana, Eladio, Oliveros-Ramos, Ricardo, and Tam, Jorge
Abstract:: We define the notion of sustainable yields for ecosystem, with particular emphasis on long-run consistency between ecological and economic conflicting objectives. We provide a way to compute sustainable yields by means of a viability analysis of generic ecosystem models with harvesting. We apply our approach to a Lotka–Volterra model of...

Creator:: Townsend, Ralph
Abstract:: At a 1969 conference, Coase provided rather scathing comment on a paper co-authored by Scott (Economics of Fisheries Management: A Symposium, University of British Columbia, Vancouver, 1970.) That comment is remarkable inasmuch as Scott thought that he was using a transactions cost approach based upon Coase (1960). This paper will...

Abstract:: The central objective of fishery management is to ensure the sustainability and profitability of the resource base. The importance of the fish stock's age-structure is increasingly recognized in economics and ecology. Still, current policies predominately rely on the aggregate biomass. We carefully calibrate a detailed model on the North-East Arctic...

Creator:: Ramos, Jorge, Santos, Miguel N., Whitmarsh, David, and Monteiro, Carlos C.
Abstract:: 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...

Creator:: Ramos, Jorge, dos Santos, Miguel N., Whitmarsh, David, and Monteiro, Carlos C.
Abstract:: 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...

Creator:: Pierre Nolasque, Meke Soung
Abstract:: Cameroon is a country of Central Africa, with 402 km coastline where occur intense industrial and small scale marine, multispecies/gears fishing activities. Fishing accounts for 5.2% of GDP in the primary sector and 1.7% of GDP. The Ministry of Livestock’s, Fisheries and Animal Industries is responsible of the fisheries policy...

Creator:: Ramos, Jorge, Neves Santos, Miguel, and Costa Monteiro, Carlos
Abstract:: 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...

Abstract:: 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...
