bioeconomic model for a three zone Marine Protected Area a case study of medes islands northwest mediterranean
Ices Journal of Marine Science, 2009Co-Authors: Gorka Merino, Francesc Maynou, Jean BoncoeurAbstract:Merino, G., Maynou, F., and Boncoeur, J. 2009. Bioeconomic model for a three-zone Marine Protected Area: a case study of Medes Islands (northwest Mediterranean). - ICES Journal of Marine Science, 66: 147-154.The bioeconomic effects of establishing a three-zone Marine Protected Area (MPA) are investigated. The division of the Area into zones, fully Protected, partially Protected, and a fishing zone, permits a combination of extractive (fishing) and touristic activities. The consequences for species conservation, commercial fishing, and touristic activities are analysed for a set of different Area-size distributions and fishing-effort levels. The model parameters are based on Medes Islands MPA in the northwestern Mediterranean. For the case study, the economic analysis includes revenues from scuba diving, glass-bottom boat trips, and commercial fisheries. Our results help to illustrate the benefits of the coexistence of extractive and non-extractive activities in a realistic, three-level MPA.

socioeconomic implications of recreational shore angling for the management of coastal resources in a mediterranean Marine Protected Area
Fisheries Research, 2011Co-Authors: Toni Font, Josep LloretAbstract:Roving creel surveys of recreational shore fishing were conducted in 2007 in the Marine reserve of Cap de Creus (NW Mediterranean) to assess the socioeconomic implications of this leisure activity. Even though an angler spends on average around 600€ per year in fishing supplies and car fuel, the economic impact for the villages belonging to the Marine reserve is limited because most (95%) anglers were visitors who were not lodged in any coastal village of the Park and therefore did not spend on local services and accommodation. However, the willingness of more than half of the anglers to pay a fee for fishing in the Marine Protected Area supports the social and economic value of angling in the Protected Area.

spearfishing pressure on fish communities in rocky coastal habitats in a mediterranean Marine Protected Area
Fisheries Research, 2008Co-Authors: Josep Lloret, Toni Font, Nuria Zaragoza, David Caballero, Margarida Casadevall, Victoria RieraAbstract:Abstract This study constitutes the first empirical investigation in the Mediterranean Sea quantifying in situ the pressure of spearfishing on fish communities in rocky coastal habitats in the Mediterranean. The investigation was carried out in the Cape Creus Marine Protected Area (MPA). Overall, 20 fish species and 1 invertebrate species were identified (three were coastal pelagic and the rest rocky benthic or demersal). In terms of abundance, two omnivorous species made up the 44% of the catch but in terms of weight, the main part (77%) of the catches relied on seven piscivorous (i.e. top-predator) fish (with trophic level values greater than 3.80). With the exception of three fish, the specie's intrinsic vulnerability values ranged between 40 and 90 (out of 100), implying a moderate to very high vulnerability to fishing. Spearfishing mainly targets large individuals measuring more than 30 cm in length. It is estimated that the total annual biomass extracted by spearfishing in the MPA is equivalent to ca. 40% of the total biomass extracted annually by artisanal (commercial) fishing. Overall, results highlight the pressure spearfishing exerts on the reproductive potential of fish species in rocky habitats along the Mediterranean coast, particularly those that are vulnerable (i.e. long lived and slow growing species with low reproductive potential) and have a higher trophic level. Results support the assumption that spearfishing can induce changes in both the trophic structure and the intrinsic vulnerability of taxa in the catch. Considering the biological implications of spearfishing, management should be supported by additional regulations in order to protect species that are vulnerable and have a higher trophic level.

Sea of possibilities: Old and new uses of remote sensing data for the enforcement of the Ascension Island Marine Protected Area
Marine Policy, 2018Co-Authors: Thomas Appleby, Brendon Moorhouse, Chad Staddon, Judith Brown, Matthew Studley, Emma BeanAbstract:Very large Marine Protected Areas are in danger of becoming 'paper parks'. This paper uses an interdisciplinary team to investigate the use of remote sensing technologies to provide sufficient evidence for effective fisheries management. It uses the intended Marine Protected Area around Ascension Island as a case study. Satellite technology provides opportunities to detect the presence of fishing vessels but because of difficulties with data interpretation, it is unlikely to be a sole source of evidence for prosecutions. Developing drone technology and traditional over-flights by aerial surveillance may supplement satellite technology with 'eyewitness’ evidence. Well-crafted regulations will be able to make some use of this data, but the evidential requirements of criminal courts make prosecutions difficult to pursue. There is some scope to expand management opportunities through vesting the fishery in a public body and pursuing offenders through civil law, this approach having a different suite of remedies. Other opportunities lie in giving very large Marine Protected Areas legal personality which has similar advantages and additional reputational benefits. Using remote sensing data in the civil court poses evidential problems. An alternative approach is to collate data around frequent infringers and, by negatively impacting on their reputation, restrict their ability to obtain insurance, finance, access to fisheries and market access. This is exemplified in port state measures by fisheries authorities and chain of custody requirements by labelling bodies. Data sharing raises challenges with intellectual property and coordination. The paper demonstrates that there are opportunities to make VLMPAs work more effectively.
