Повний текст джерелаGlobal changes induce high pressure on marine ecosystems, biodiversity and fisheries. In thatregard many scientists advocate the use of an ecosystem-based fisheries management (EBFM).However, the operationalization of such an ecosystem-based approach remains challenging. Thisthesis gives insight into the operationalization of EBFM for tropical coastal fisheries. To achievethat we propose a multi-species, multi-fleet and multi-criteria model of intermediate complexity(MICE), taking into account the impacts of global changes. The model is calibrated for theGuyanese small-scale coastal fishery. At local scale, global warming, the increase of populationand the variations of mangrove surface are considered as the main drivers of global changes.From the calibrated model, several fishing management strategies and environmental scenariosare compared in the long-run. In this context, the first results published (chapter 3) show thedetrimental impact of climate change on both marine biodiversity and fishery production. Thispaper also highlights the major role of ecological competition between species. Then, in thechapter 4, by comparing the bio-economic results obtained under each fishing managementstrategy, this research demonstrates the interest of Ecoviability strategies in terms ofsustainability and ecologico-economic reconciliation. The last results displayed in this thesis, inchapter 5, underline the positive impact of mangrove on ecologico-economic sustainability of thecoastal fishery, even if it is insufficient to balance the negative impact of warming. Beyond theseresults, this thesis brings a series of important transverse contributions. First, methodologically,this research permits to show the benefits of MICE to operationalize EBFM. Then, by highlightingthe major ecological factors of the ecosystem with on the one hand the interaction ofcompetition and on the other hand the environmental filters, the work sheds light on theecological complexities necessary for the EBFM. Finally, by evaluating and comparing theecologico-economic performances of several fishing strategies, this research permits to outlinepolicy recommendations to move towards the sustainability of the Guyanese coastal fishery andtowards EBFM, in the face of global changes

Повний текст джерелаThe exploitation of terrestrial energy and mineral resources is limited by the rapid increase of the world's population. It was only after the Second World War that States realised that they had to control the ocean in order to extract its resources. 1982 marks the adoption of the United Nations Convention on the Law of the Sea. The maritime are: was then divided into zones, over which coastal States most often had rights. This division allowed for a better exploitation of maritime resources. In the territorial sea, for example, States could set up electricity production systems from renewable sources. Further, in the exclusive economic zone, States could allow the exploration and exploitation of hydrocarbons. Finally, on the continental shelf, the evolution of technology will soon allow us to exploit marine mineral resources. The central question is whether it is possible to exploit these resources in a sustainable way without destroying the marine environment. The protection of the environment cannot exist without a strong and applied legislation. It must be a bulwark against the actions of companies or States that have little regard for the long-term impact of their actions. The ocean, immense, with invisible and mysterious bottoms, is vulnerable. Its protection can only take place when the general public, States and companies understand its importance for the survival of Humanity. It is the duty of the men and women of law to render this protection effective

Повний текст джерелаOver the last few years the sea has known a multiplication of its modes of exploitation. From now on, marine areas must be shared between the traditional users (fishing, marine cultures, sea traffic) and the new users of the sea (industrial activities, leisure), to whom is added an environmental use. Conflicts which arise from this competition in the use of these fragile environments require an intervention which needs to be increased and renewed by public authorities. Arbitration between these activities involves research by the authorities of a balance between the exploitation and the environmental protection of the sea. Despite recent reforms, the study of different administrations in charge of the sea has pointed out that the dispersed skills lead to the inefficient management of conflicts of use. Solutions are possible to optimize the organization and coordination in the State's policies on maritime affairs. These conflicts are then considered in connection with the regulation of the different activities. Preventing these conflicts of use requires that planned marine activities may be integrated into a management approach of the sea and the coast and improved by more effective tools and better coordination. However, after consultation, the development of European and national integrated maritime policies, applied at relevant scales, provide a better overall shared management of the sea. Finally, the resolution of these conflicts implies that civil society and the courts are more involved in the process and have to specialize

Повний текст джерелаEven though Japan is the first country to have produced cultured pearls with corporate names like Mikimoto and Tasaki becoming synonymous with the pearl industry itself, little academic work bas been done on the subject with even fewer Works being available in occidental languages. The traditional image of Japanese women divers gathering pearls from the seabed is dismantled in the face of a Japanese industry based on the latest techniques in biotechnology and generating tens of billions of yen per year. Japan's position at the center of the world pearl business bas faded due essentially to the structure of the Japanese pearl industry itself. A structure, reflecting Japan's monopoly of production and distribution, focused almost uniquely on production with an over emphasis on the akoya pearl is being forced to restructure to one recognising competitive production from abroad, a diversification of pearl products and vigorous attention to marketing and distribution in the global economy. The decline in akoya pearl production resulting from a high mortality rate of the pearl oyster reminds us that this industry is dependant upon the maintenance of a marine environment at its optimal natural condition. Production stability is inextricably connected to both the regulation of access to the sea and to the competing alternative usages of the sea which in some cases have brought about degradation of the marine environment. There is a need to readapt the whole pearl industry to a new paradigm: pearl culture is a unique process irrevocably demanding total respect for natural boundaries in the marine environment so as to produce what the market is asking for : quality pearls

Повний текст джерелаHabitat and trophic ecology of albacore (Thunnus alalunga) in the North-East Atlantic were studied through (1) the analysis of annual catch per unit of effort (CPUE), (2) sonic tracking and echosounding, (3) stomach content analysis and (4) fat content measurements. The vertical habitat of smaller individuals appears shallower, and limited by the seasonal thermocline in the case of age-2 albacore. An important geographical variability of the diet is shown, and suggests a possible geographical variability in the associated feeding behaviour. Stomach repletion appears higher, and ability to store energy lower and more variable in smaller individuals, which suggests higher energetic needs for these individuals. These results have implications on three aspects regarding the exploitation and assessment of the population: - a variability in the catchability of age-2 albacore, related to the variability of their thermal vertical habitat, can induce an important fishing mortality when their thermal habitat favours high catchabilty levels, and introduce a bias in the stock assessment if the environmental influences on catchability are not taken into account. - a geographical variability of albacore catchability by trolling and baitboat, related to the geographical variability of their feeding behaviour, could also introduce a bias in CPUE standardization. - a higher natural mortality in smaller individuals, due to important energetic needs related to their growth and to their physiological restrictions
