An experimental evaluation of the effectiveness of beach ashtrays in preventing marine contamination BABT
Widmer,Walter Martin; Reis,Rodrigo Arantes.
In this study, hypotheses concerning the use of beach ashtrays were experimentally tested. Results indicated that the mean rate of abandonment of this equipment was low (1.5%). The mean amount of cigarette stubs (3.4 items/ashtray) was greater than mean amounts of other types of litter. People with different socioeconomic profiles had different perceptions regarding the issues associated with beach debris. These results indicated that beach ashtrays could be useful to prevent the contamination of these environments and that differences in socioeconomic characteristics of beachgoers could partially explain the differences in perceptions regarding the presence of waste on the beaches. This information could now be used by coastal managers to plan strategies...

Can Resilience be Reconciled with Globalization and the Increasingly Complex Conditions of Resource Degradation in Asian Coastal Regions? Ecology and Society
Armitage, Derek; Wilfrid Laurier University; darmitag@wlu.ca; Johnson, Derek; Centre for Maritime Research; dsjohnson@marecentre.nl.
This paper explores the relationship between resilience and globalization. We are concerned, most importantly, with whether resilience is a suitable conceptual framework for natural resource management in the context of the rapid changes and disruptions that globalization causes in social-ecological systems. Although theoretical in scope, we ground this analysis using our experiences in two Asian coastal areas: Junagadh District in Gujarat State, India and Banawa Selatan, in Central Sulawesi, Indonesia. We present the histories of resource exploitation in the two areas, and we attempt to combine a resilience perspective with close attention to the impact of globalization. Our efforts serve as a basis from which to examine the conceptual and practical...

Constraints to the implementation of effective environmental management in coastal areas of developing countries Anais da ABC (AABC)
Wagener,Angela de L.R..
This paper addresses the limitations the scarcity of reliable scientific information poses to the implementation of effective and sustainable coastal management programmes in developing countries. Alternatives to the current monitoring approaches are suggested as to improve information level on the state of the environment and to decrease data gap on past conditions. The paper aims at encouraging the redesign of monitoring practices in developing countries as to be ground on the best actual scientific knowledge.

Five critical questions of scale for the coastal zone ArchiMer
Swaney, D. P.; Humborg, C.; Emeis, K.; Kannen, A.; Silvert, W.; Tett, P.; Pastres, R.; Solidoro, C.; Yamamuro, M.; Henocque, Yves; Nicholls, R..
Social and ecological systems around the world are becoming increasingly globalized. From the standpoint of understanding coastal ecosystem behavior, system boundaries are not sufficient to define causes of change. A flutter in the stock market in Tokyo or Hong Kong can affect salmon producers in Norway or farmers in Togo. The globalization of opportunistic species and the disempowerment of people trying to manage their own affairs on a local scale seem to coincide with the globalization of trade. Human-accelerated environmental change, including climate change, can exacerbate this sense of disenfranchisement. The structure and functioning of coastal ecosystems have been developed over thousands of years subject to environmental forces and constraints...

Red-drum (Sciaenops ocellata) farming in Martinique: a new prospect for Caribbean marine aquaculture ? ArchiMer
Paquotte, Philippe.
(not controled OCR) like most other caribbean islands, martinique suffers a reduction in fisheries resources and is now a net importer of seafood products since no major expansion of aquaculture production has been done. nevertheless, this island has numerous assets for marine aquaculture development : tropical clean waters, developed infrastructures and market channels, financial support for research, training and extension due to its tight political and economic connection with france. red drum is a subtropical fish introduced in martinique in 1985 from the south of usa for aquaculture purposes. from 1987 to 1993, ifremer worked on rearing techniques in martiniquan conditions. once the farming techniques were perfected, questions raised about red drum...

Shellfish culture in France : present status and new approaches to optimise production ArchiMer
Goulletquer, Philippe.
France is presently one of the leading countries in Europe for shellfish production with 152,000 metric tonnes of the Pacific cupped oyster C. gigas, 2,500 tonnes of flat oyster O. edulis, and more than 60,000 tonnes of mussels M. edulis and M. galloprovincialis. Moreover, species like the pearl oyster Pinctada margaritifera in French Polynesia, and on the Atlantic coastline the scallop Pecten maximus and the Manila clam Tapes philippinarum contribute significantly to the overall landings. . Since traditional rearing areas are now almost overloaded, new management practices are currently under review to optimise and develop shellfish culture. Besides the products resulting from genetic research (e.g. triploids, tetraploids and disease resistant strains),...

Surveillance écologique et halieutique des sites de centrales nucléaires littorales : évaluation et perspectives ArchiMer
Quintin, Jean-yves; Bordet, F.
Electricité de France (EDF) has asked Institut Français de recherche pour l'exploitation de la mer (IFREMER) to monitor the coastal marine environment and its living resources around nuclear power plants along the French coast. Started in 1974, these investigations were undertaken in the areas of Gravelines, Le Blayais, Paluel, Flamanville, and Penly; the objective is to detect any impact of the open-circuit water cooling system, as well as any differences in the marine environment itself. To examine this question, IFREMER has set up a program called Impact des Grands Aménagements (IGA). It has evolved according to the results obtained and now integrates the specificity of each site in a global program common to all. The nature and the problems of impact...

The structure of rocky reef fish assemblages across a nearshore to coastal islands' gradient in Southeastern Brazil Neotropical Ichthyology
Gibran,Fernando Zaniolo; Moura,Rodrigo Leão de.
Local assemblages of fishes associated with reefs are influenced by interactions among the availability of larvae and survival of recruits with subsequent biotic and abiotic forcing, as well as by periodic and episodic disturbances of varying natures and magnitudes. Therefore, besides being structurally heterogeneous and patchily distributed, reef systems are strongly context-dependent due to the influence of a broad array of ecological processes. In order to assess interactions of local factors that influence the distribution and abundance of reef fishes within a coastal mosaic of rocky reefs, we tested the null hypothesis of no significant variation in fish assemblage structure, by comparing 33 sites along the northern coast of the São Paulo State,...

The Systems Approach Framework as a Complementary Methodology of Adaptive Management: a Case Study in the Urban Beaches of Barcelona Ecology and Society
The Systems Approach Framework is a methodological framework designed to enhance the efficacy of human decision-making processes within social-ecological systems with regard to sustainability. The objective of resilience adaptive management is to either maintain the system within the current regime such that the desired ecosystem goods and services continue to be delivered, or to move the system phase to a preferred regime. Although the objectives of the two frameworks are not exactly the same, there are considerable complementarities between them. Through application of the Systems Approach Framework in a case study regarding the urban beaches of Barcelona, Spain, we present some of the main findings revealed during the model construction and stakeholder...

Use of a mathematical model to estimate the impact of shrimp pen culture at Patos Lagoon estuary, Brazil Anais da ABC (AABC)
POERSCH,LUÍS H.; MILACH,ÂNGELA M.; CAVALLI,RONALDO O.; WASIELESKY,WILSON JR.; MÖLLER,OSMAR; CASTELLO,JORGE P..
Ecological modeling has been used as a tool to estimate potential impacts caused by aquaculture to the surrounding environment. In this work, a mathematical model was applied to estimate the maximum amount of pink shrimp (Farfantepenaeus paulensis) culture units (3,100m2 pen enclosures) that could be installed at two shallow estuarine bays of Patos Lagoon (known as Coreia and Porto do Rei) with no significant effects on either water quality or viability of the culture system. To calibrate the model, information about the culture of Litopenaeus vannamei and F. paulensis as well as field data (influence of netting material, water current speed and nitrogen concentrations) were used. Under a bad scenario (water current velocity of 0.01m s–1 and a mesh...
