A Reference Guide on t he Use o f Indicators for Integrated Coastal Management OceanDocs
Belfiore, S.; Balgos, M.; McLean, B.; Galofre, J.; Blaydes, M.; Tesch, D..
This first issue is devoted to the use of indicators for ICAM, and is a direct result of the IOC-DFO-NOAA-CSMP International Workshop on the same topic, organised in May 2002, in Ottawa. Based on a background paper prepared by the Center for the Study of Marine Policy (University of Delaware) in preparation for the workshop, the aim of this Reference Guide is to present a literature review on the use of indicators around the world, from various programmes and projects, at global, regional, national and local scale.The need for indicators and reporting techniques which reflects the performance of coastal management projects and programmes and reveals the complex relationship that exist between coastal ecosystem health and anthropogenic activities,...

Aire marine protégée du Bamboung OceanDocs
La première aire marine protégée communautaire (AMP) du Sénégal a vu le jour dans le delta du Sine Saloum au niveau du bolong du bambooung. Cette action de préservation et de conservation s'inscrit dans un contexte de baisse globale des ressources halieutiques. Depuis le mois d'Avril 2003, l'aire Marine Protégée Communautaire du Bamboung est balisée et surveillée par des bénévoles des villages périphériques. La mise en place de cette aire protégée s'est faite grâce à une réelle volonté locale.

Avances en el diseño de una red de áreas marinas protegidas: estrategia de conservación para el norte del Caribe Continental colombiano OceanDocs
Alonso-C., D.; Segura-Quintero, C.; Castillo-Torres, P.; Gerhantz-Muro, J..
El establecimiento de redes de áreas marinas protegidas (AMP) ecológicamente representativas es una importante herramienta de manejo con que se cuenta para proteger la biodiversidad y regular el uso de los recursos naturales marinos y costeros. Este trabajo tuvo como objetivo principal aportar elementos para el futuro diseño de una red de AMP para el norte del Caribe continental colombiano. Con la participación de expertos nacionales se identificaron 51 objetos de conservación (OdC) a diferentes niveles de organización biológica (sistemas ecológicos, comunidades ecológicas relevantes y especies) y sitios de importancia arqueológica, histórica y cultural indígena. Para cada uno de estos objetos se definieron metas de conservación cuantitativas por estrato o...

Collaborative Engagement of Local and Traditional Knowledge and Science in Marine Environments: A Review Ecology and Society
Thornton, Thomas F; University of Oxford; thomas.thornton@ouce.ox.ac.uk; Scheer, Adela Maciejewski ; McGill University; admasch@gmail.com.
Local and traditional ecological knowledge (LTK) is increasingly recognized as an important component of scientific research, conservation, and resource management. Especially where there are gaps in the scientific literature, LTK can be a critical source of basic environmental data; this situation is particularly apparent in the case of marine ecosystems, about which comparatively less is known than terrestrial ones. We surveyed the global literature relating to the LTK of marine environments and analyzed what knowledge has been collected and with what aims and results. A large proportion of LTK which has been documented by researchers consists of species-specific information that is important for traditional resource use. However, knowledge relating to...

Composition, density and biomass of fish community from the surf zone as a function of the lunar cycle at Miramar Beach in Cabedelo, Paraíba Neotropical Ichthyology
Pessoa,Willy Vila Nova; Ramos,Jonas de Assis Almeida; Oliveira,Paulo Guilherme Vasconcelos de.
ABSTRACT The influence of the moon cycles on the ichthyofauna has been little studied in the surf zone. In this study, the number of species, density and biomass were evaluated as a function of the moon. A total of 49 species distributed in 24 families were captured in two areas of Miramar beach. The mean density was significant high in the weaning and low in the new moon, while density and biomass together showed differences for areas. The most abundant species were Anchoa tricolor and Trachinotus falcatus (new moon), and Anchovia clupeoides showed significant differences in the waning moon. The RDA indicates that turbidity influenced significantly the presence of two species group. The group I were represented by Stellifer brasiliensis, Trachinotus...

Emergence of Global Adaptive Governance for Stewardship of Regional Marine Resources Ecology and Society
Folke, Carl; Stockholm Resilience Centre, Stockholm University; Beijer Institute of Ecological Economics, Royal Swedish Academy of Sciences; carl.folke@beijer.kva.se.
Overfishing has historically caused widespread stock collapses in the Southern Ocean. Until recently, illegal, unreported, and unregulated (IUU) fishing threatened to result in the collapse of some of the few remaining valuable fish stocks in the region and vulnerable seabird populations. Currently, this unsustainable fishing has been reduced to less than 10% of former levels. We describe and analyze the emergence of the social-ecological governance system that made it possible to curb the fisheries crisis. For this purpose, we investigated the interplay between actors, social networks, organizations, and institutions in relation to environmental outcomes. We drew on a diversity of methods, including qualitative interviews, quantitative social network and...

Estudios de algunas características físicas y biológicas de la columna de agua en Bahía Chile-Isla Greenwich OceanDocs
Cornejo, María P.; Arcos, F..
Se determinaron algunas características físicas y biológicas de la columna de agua en Bahía Chile, Isla Greenwich, por medio de la distribución espacial de temperatura, salinidad y clorofila "a", durante el verano austral (febrero de 1990). Las distribuciones verticales de las isotermas, isohalinas, isopicnas e isolíneas de clorfila "a" muestran que la circulación predominante es termohalina, influenciada por la topografía de la bahía, con un flujo subsuperficial que entra por el lado noroccidental de la misma y se dirige hacia el centro (siguiendo la topografía), aflora en el extremo interior y sale superficialmente por el lado oriental.

Heavy minerals in the Nigeria river sediments OceanDocs
Awosika, L.F.; Akpati, B.N..
Analysis of 450 sediment samples from various rivers in Nigeria have resulted in the identification of seven major drainage systems some of which may be potential sources of heavy mineral contribution to the continental shelf. The seven major drainage systems are: (1) Niger/Benue drainage system with coarse to medium size sediments and a high of 90% opaque mineral concentration in many cases. Some gem heavy minerals like garnet and zircon are also recorded. (2) Gombi drainage system: consists of medium to coarse sand. Opaque mineral concentrations are also high. Up to 90.59% at station BO.99.3. (3) Bauchi Plateau drainage system: Sediments from this drainage system are very coarse and highly angular. This drainage system records the highest overall opaque...

La Gouvernance de la Biodiversite Marine et Cotiere dans le Golfe de Guinee. OceanDocs
Etoga, G. Y. L..
Biodiversity is a holistic concept which encompasses what the scientific literature describes as inter-specific diversity (diversity between species), intra-specific diversity (genetic diversity) and diversity of ecosystems. As a support of life, the preservation of biodiversity in terrestrial and marine habitats is of primary importance for the ecological balance of the Earth. Moreover, it is essential for human beings whose lifestyle depends on nature. The value of biodiversity lies with the opportunities provided to mankind to adapt to a changing environment. Concerning specifically the seas and oceans that constitute ¾ of the planet and 90% of the biosphere, there is a renewed ‘ecological awareness’ at the global level on the need to preserve marine...

Low nutrient availability is not the single factor limiting <i>Artemia</i> cyst productivity in salinas of NE-Brazil OMA
Camara, M.R.; Tackaert, W..
<i>Artemia</i> production in NE-Brazil began in 1977 after a successful inoculation of <i>Artemia franciscana</i> (San Fransisco Bay, California, USA) in solar salt ponds in Macau (RN state) and was followed by a rapid natural dispersion of this crustacean to all saltwork areas in the region. <i>Artemia</i> is basically produced in extensive conditions as an opportunistic by-product collected from salt evaporation ponds. This type of approach has, however, brought about very unpredictable results, as is reflected in a drastic decline of cyst production occurring from 1982 onwards. Low nutrient concentrations and a drop in primary productivity have been suggested as possible causes for this decline. In order to provide a...
