Distribution, composition, and abundance of ichthyoplankton in three marine protected areas of the Colombian Pacific 50
Beltrán-León,Beatriz Susana; Morales Osorio,Yaneth Alicia.
ABSTRACT With the purpose of characterizing ichthyoplankton in three marine protected areas (Sanquianga National Natural Park, Gorgona National Natural Park and Malpelo Fauna and Flora Sanctuary) in the Colombian Pacific during November 2009, scientific expeditions were carried out to obtain 56 samples by trawling with bongo nets. 3,155 / 10 m2 fish larvae were captured distributed in 1,553 larvae / 10 m2 (49.22 %) for the PNN Sanquianga; 1,411 larvae / 10m2 (44.72 %) for the Gorgona PNN and 191 larvae / 10m2 (6.05 %) for the Malpelo SFF. The main families were Engraulidae (PNN Sanquianga), Bregmacerotidae (PNN Gorgona) and Phosichthyidae (SFF Malpelo). The NMS community analysis shows that the location of the PNN Sanquianga (coastal), PNN Gorgona...

Ichthyofauna of the marine area of Vía Parque Isla Salamanca, Magdalena, Colombia 50
Sánchez-Rodríguez,Diana C.; Acero P.,Arturo; Viloria-Maestre,Efraín; Villa-Navarro,Francisco A.; Saldaña,Patricia.
ABSTRACT Monthly samplings of fish catches obtained by traditional beach seine were carried out between 2006 and 2007, recording an important portion of the Caribbean ichthyofauna of the continental shelf:10 114 individuals belonging to 16 families and 31 species. The families Carangidae and Sciaenidae are mentioned among the most widely represented in the Caribbean, while the most abundant species was Oligoplites saurus. From the list of species, seven are included in the Red Book of Marine Fishes of Colombia; five between the categories Critically Endangered (CR) and Vulnerable (VU), and two in the category Near Threatened (NT). These results are a technical and scientific input for decision making, to fulfill the conservation and management mission...

Achieving Success under Pressure in the Conservation of Intensely Used Coastal Areas 7
Micheli, Fiorenza; Hopkins Marine Station, Stanford University, California, USA; micheli@stanford.edu; Niccolini, Federico; Department of Economics, University of Macerata, Macerata, Italy; fniccolini@unimc.it.
Understanding how biological conservation and socioeconomic development can be harmonized in social-ecological systems is at the core of sustainability science. We present the case of a Mediterranean marine protected area (MPA), the Tavolara-Punta Coda Cavallo MPA, that exhibits high ecological performance under intense pressure from fishing, tourism, and coastal development. This case study illustrates how socioeconomic development and significant conservation benefits can coexist, even in a challenging context. Based on this case study, we present a framework for what elements and interactions have determined the high ecological performance of this MPA, and highlight the key leverages that have enabled ecosystem recovery. In particular, the most critical...

Moving Toward Spatial Solutions in Marine Conservation with Indigenous Communities 7
Ban, Natalie C; Project Seahorse; University of British Columbia Fisheries Centre; n.ban@fisheries.ubc.ca; Vincent, Amanda C.J.; Project Seahorse; University of British Columbia Fisheries Centre; a.vincent@fisheries.ubc.ca.
Community and resource user support has often been declared as essential to achieving globally agreed targets for marine protection. Given that indigenous people in Canada have resource use rights, we engaged two indigenous communities in British Columbia for their views on marine planning and protected areas. We developed a three-phased approach for executing our research: building research partnerships, carrying out individual interviews, and holding community discussion sessions. Participants expressed a common goal of recovering depleted species and ensuring the sustainability of indigenous fishing. We found strong support for spatial protection measures, and significant overlaps amongst participants in the areas suggested for protection. The most...

The capacity to adapt?: communities in a changing climate, environment, and economy on the northern Andaman coast of Thailand 7
Bennett, Nathan J.; Institute for Resources, Environment and Sustainability, University of British Columbia; nathan.bennett@ubc.ca; Dearden, Philip; Department of Geography, University of Victoria; pdearden@office.geog.uvic.ca; Murray, Grant; Institute for Coastal Research, Vancouver Island University; Grant.Murray@viu.ca; Kadfak, Alin; School of Global Studies, University of Gothenburg; alin.kadfak@globalstudies.gu.se.
The health and productivity of marine ecosystems, habitats, and fisheries are deteriorating on the Andaman coast of Thailand. Because of their high dependence on natural resources and proximity to the ocean, coastal communities are particularly vulnerable to climate-induced changes in the marine environment. These communities must also adapt to the impacts of management interventions and conservation initiatives, including marine protected areas, which have livelihood implications. Further, communities on the Andaman coast are also experiencing a range of new economic opportunities associated in particular with tourism and agriculture. These complex and ongoing changes require integrated assessment of, and deliberate planning to increase, the adaptive...

The Political Economy of Cross-Scale Networks in Resource Co-Management 7
Adger, W. Neil; Tyndall Centre for Climate Change Research; n.adger@uea.ac.uk; Brown, Katrina; University of East Anglia; k.brown@uea.ac.uk; Tompkins, Emma L.; University of East Anglia; e.tompkins@uea.ac.uk.
We investigate linkages between stakeholders in resource management that occur at different spatial and institutional levels and identify the winners and losers in such interactions. So-called cross-scale interactions emerge because of the benefits to individual stakeholder groups in undertaking them or the high costs of not undertaking them. Hence there are uneven gains from cross-scale interactions that are themselves an integral part of social-ecological system governance. The political economy framework outlined here suggests that the determinants of the emergence of cross-scale interactions are the exercise of relative power between stakeholders and their costs of accessing and creating linkages. Cross-scale interactions by powerful stakeholders have...

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, we explored relationships...

Controversies and consensus on the lionfish invasion in the Western Atlantic Ocean 7
This study investigates how the lionfish (Pterois sp.) invasion of the Western Atlantic Ocean has been socially constructed by natural scientists, the media, and stakeholders associated with various marine protected areas in the Caribbean. By examining the use of data and metaphors by these actors, I identify where invasion discourses converge and diverge. Although consensus exists regarding the non-nativeness, introduction vector, and successful establishment of lionfish throughout the region, I also identify uncertainty surrounding lionfish impact and controversies regarding lionfish management and control. The dominant discourse frames lionfish as a threat and control efforts as a war to keep the enemy at bay, and promotes lionfish hunting and...

Fish, fishers, seals and tourists: Economic consequences of creating a marine reserve in a multi-species, multi-activity context 5
Boncoeur, Jean; Alban, Frederique; Guyader, Olivier; Thebaud, Olivier.
This paper investigates some economic consequences of creating a marine reserve on both fishing and ecotourism, when the range of controllability of fishing effort is limited and the impact of the reserve on ecosystem is considered. The issue is illustrated by the example of creating a no-take zone in part of a region where fishing is managed through a limited entry license system, and which is inhabited by two interacting stocks: a stock of prey (fish) and a stock of predators (seals). While the former is targeted by commercial fishing, the latter is not subject to harvest but is a potential basis for a commercial non-extractive activity (seal watching). Analysis is conducted with the help of a bioeconomic model combining the features of marine reserve...

Connecting MPAs - eight challenges for science and management 5
Lagabrielle, Erwann; Crochelet, Estelle; Andrello, Marco; Schill, Steven R.; Arnaud-haond, Sophie; Alloncle, Neil; Ponge, Benjamin.
Connectivity is a crucial process underpinning the persistence, recovery, and productivity of marine ecosystems. The Convention on Biological Diversity, through the Aichi Target 11, has set the ambitious objective of implementing a ‘well connected system of protected areas’ by 2020. This paper identifies eight challenges toward the integration of connectivity into MPA network management and planning. A summary table lists the main recommendations in terms of method, tool, advice, or action to address each of these challenges. Authors belong to a science–management continuum including researchers, international NGO officers, and national MPA agency members. Three knowledge challenges are addressed: selecting and integrating connectivity measurement metrics;...

Variation that can be expected when using particle tracking models in connectivity studies 5
Hufnagl, Marc; Payne, Mark; Lacroix, Genevieve; Bolle, Loes J.; Daewele, Ute; Dickey-collas, Mark; Gerkema, Theo; Huret, Martin; Janssen, Frank; Kreus, Markus; Paetsch, Johannes; Pohlmann, Thomas; Ruardij, Piet; Schrum, Corinna; Skogen, Morten D.; Tiessen, Meinard C. H.; Petitgas, Pierre; Van Beek, Jan K. L.; Van Der Veer, Henk W.; Callies, Ulrich.
Hydrodynamic Ocean Circulation Models and Lagrangian particle tracking models are valuable tools e.g. in coastal ecology to identify the connectivity between offshore spawning and coastal nursery areas of commercially important fish, for risk assessment and more for defining or evaluating marine protected areas. Most studies are based on only one model and do not provide levels of uncertainty. Here this uncertainty was addressed by applying a suite of 11 North Sea models to test what variability can be expected concerning connectivity. Different notional test cases were calculated related to three important and well-studied North Sea fish species: herring (Clupea harengus), and the flatfishes sole (Solea solea) and plaice (Pleuronectes platessa). For sole...

Ocean Futures Under Ocean Acidification, Marine Protection, and Changing Fishing Pressures Explored Using a Worldwide Suite of Ecosystem Models 5
Olsen, Erik; Kaplan, Isaac C.; Ainsworth, Cameron; Fay, Gavin; Gaichas, Sarah; Gamble, Robert; Girardin, Raphael; Eide, Cecilie H.; Ihde, Thomas F.; Morzaria-luna, Hem Nalini; Johnson, Kelli F.; Savina-rolland, Marie; Townsend, Howard; Weijerman, Mariska; Fulton, Elizabeth A.; Link, Jason S..
Ecosystem-based management (EBM) of the ocean considers all impacts on and uses of marine and coastal systems. In recent years, there has been a heightened interest in EBM tools that allow testing of alternative management options and help identify tradeoffs among human uses. End-to-end ecosystem modeling frameworks that consider a wide range of management options are a means to provide integrated solutions to the complex ocean management problems encountered in EBM. Here, we leverage the global advances in ecosystem modeling to explore common opportunities and challenges for ecosystem-based management, including changes in ocean acidification, spatial management, and fishing pressure across eight Atlantis (atlantis.cmar.csiro.au) end-to-end ecosystem...

Herbivorous fishes and the potential of Caribbean marine reserves to preserve coral reef ecosystems 5
Kopp, Dorothee; Bouchon-navaro, Yolande; Louis, Max; Mouillot, David; Bouchon, Claude.
1. The development of macroalgae to the detriment of corals is now one of the major threats to coral reefs. Herbivorous fishes are partly responsible for algal regulation on coral reefs and their overexploitation favours the shift from scleractinian coral-dominated systems towards macroalgae-dominated systems. 2. Marine protected areas (MPAs) that have been established worldwide may benefit coral reefs through the maintenance of high densities of herbivorous fishes which regulate algal growth. 3. The paper assesses whether small MPAs in the Caribbean are able to enhance herbivorous fish stock and by controlling macroalgae help to maintain reef ecosystems. A visual census using band-transects was undertaken around Guadeloupe island where marine reserves...

Larval Fish Swimming Behavior Alters Dispersal Patterns From Marine Protected Areas in the North-Western Mediterranean Sea 5
Faillettaz, Robin; Paris, Claire B.; Irisson, Jean-olivier.
Most demersal fishes undergo a dispersal phase as larvae, which strongly influences the connectivity among adult populations and, consequently, their genetic structure and replenishment opportunities. Because this phase is difficult to observe directly, it is frequently simulated through numerical models, most of which consider larvae as passive or only vertically migrating. However, in several locations, including the Mediterranean Sea, many species have been shown to swim fast and orient. Here we use a Lagrangian model to study connectivity patterns among three Mediterranean Marine Protected Areas (MPAs) and compare simulations in which virtual larvae are passive to simulations in which oriented swimming is implemented. The parameterization of behavior...

Seamounts, plateaus and governance issues in the southwest Indian Ocean, with emphasis on fisheries management and marine conservation, using the Walters Shoal as a case study for implementing a protection framework 5
Marsac, Francis; Galletti, Florence; Ternon, Jean-francois; Romanov, Evgeny V.; Demarcq, Herve; Corbari, Laure; Bouchet, Philippe; Roest, Walter; Jorry, Stephan; Olu, Karine; Loncke, Lies; Roberts, Michael J.; Ménard, Frédéric.
There is a growing interest in the management of seamounts of the South Western Indian Ocean (SWIO) both in waters under national jurisdictions and in the Areas Beyond National Jurisdiction (ABNJ). On the one hand, new scientific knowledge has been gathered through various oceanographic cruises during the past decade and, on the other hand, new agreements are under consideration globally to promote conservation and sustainable use of the biodiversity in the ABNJ, where the deep sea ecosystems associated to seamounts are a growing matter of concern. SWIO seamounts have attracted interests from fishing operators since the 1960s, while mining exploration contracts have been recently granted. Seamounts are known to shelter rich, fragile and poorly resilient...

Impacts of data quality on the setting of conservation planning targets using the species-area relationship 5
Metcalfe, Kristian; Delavenne, Juliette; Garcia, Clement; Foveau, Aurelie; Dauvin, Jean-claude; Coggan, Roger; Vaz, Sandrine; Harrop, Stuart R.; Smith, Robert J..
Aim : The speciesarea relationship (SAR) is increasingly being used to set conservation targets for habitat types when designing protected area networks. This approach is transparent and scientifically defensible, but there has been little research on how it is affected by data quality and quantity. Location : English Channel. Methods : We used a macrobenthic dataset containing 1314 sampling points and assigned each point to its associated habitat type. We then used the SAR-based approach and tested whether this was influenced by changes in (i) the number of sampling points used to generate estimates of total species richness for each habitat type; (ii) the nonparametric estimator used to calculate species richness; and (iii) the level of habitat...

Marine protected areas and artificial reefs: A review of the interactions between management and scientific studies 5
Claudet, Joachim; Pelletier, Dominique.
Inshore marine areas host key habitats for the biological cycle of many marine populations, but are subject to strong anthropogenic pressure. Uses of inshore areas are multiple and often give rise to conflicting interests. In this context. marine protected areas (MPAs) and artificial reefs (ARs) are increasingly regarded as interesting management measures, in that they contribute to ecosystem conservation, fisheries sustainability, and because they can be helpful in zoning coastal areas in order to reduce conflicts between users. Beyond these expected benefits, it is important to appraise whether MPAs and ARs meet managers' objectives. This review focuses on the interaction between ecological sciences and management in the purpose of establishing or...
