  • Integrated maritime policy for the European Union — consolidating coastal and marine information to support maritime spatial planning.

    Meiner, Andrus (2010)
    Launch of the Integrated Maritime Policy for the European Union in 2007 served as important factor that stimulates consolidation of coastal and marine information to support policy implementation. Policy’s action plan provides approaches for maritime governance, research and planning relevant to information. In particular, roadmap for maritime spatial planning stimulates development of coastal and marine GIS. Article reviews the current general status of coastal and marine systems and puts them in the context of the policy actions. Main focus is on formation of geospatial information platform for integrated assessment and ecosystem-based management of coastal and marine areas. Recent developments in data, indicator and information systems are summarized in European perspective: better characterization of maritime space and marine ecosystems, development of GMES Marine Core service and related in situ data collection; data harmonisation, interoperability and access, promoted by Shared Environmental Information System principles.

Une etude chimique rnontre que les extraits renferment des tannins, des flavonoi'des et des saponines qui seraient a I'origine de leurs activités
  • Standardized Catch Rates for Yellowfin (Thunnus Albacares) from the Spanish Pure Seine Fleet (1984-1995)

    Soto, M.; Morón, J.; Pallares, P. (IOTC, 2000)
    The Spanish purse seine fleet operates in a wide area of the Indian Ocean since 1984. A logbooks system provides detailed information of catches (set by set) and effort. Together with this information, an intensive work of interview during 4 years (1994-1997) has provided technical equipment data. These data have been used to estimate standardized catch per unit effort (CPUE) indices of abundance for yellowfin from the Indian Ocean. Standardized catch rates have been estimated using the Generalized Linear Model (GLM) approach. The model proposed includes factors related with the stock abundance together with factors related with catchability changes.
  • Social and cultural values of wetlands in Tanzania

    Omari, C.K. (IUCN, 1993)
    The socio-economic aspects of wetland farming and fisheries' are discussed together with the cultural values of wetlands such as scenery, sources of traditional medicine, anddiseases. The socio-political features of wetland life are mentioned as well as theinternational considerations of wetland water needs. A plea is made for more research intoindigenous knowledge of wetland values and products.
  • Dilemma of Small-scale Fishers at the Dawn of Industrial Fishing in Kenya

    Muchiri, M.S. (ICSF/ IOI, 2001)
    People of the Kenya coast have lived off the Indian Ocean for as long as memory can go. Folklore and legend reflect a history of dependence on the sea for livelihood, including fisheries. Due to technological limitation coupled with small human populations, harvesting from the sea had little effect in the past. Fishermen relied on simple fishing gear operated either from the shore or from dug-out and small planked canoes to supply needs of their families....

  • Transhipment of Tuna in Mauritius and Analysis of the Mauritian Purse-Seine Fishery, 1994-1997

    Norungee, D.; Munbodh, M. (IOTC, 1998)
    This paper presents a review of tuna transhipment in Mauritius and of the local purse-seine fishery. Mauritian purse seiners use FADs to concentrate the fish before netting them. Information is presented on catch and effort, species composition, length frequency and spatial distribution of the purse-seine catches.
  • The Status of Réunion Island (France) - Based Tuna Fisheries in the Indian Ocean

    Poisson, F.; René, F.; Guyomard, D. (1998)
    The Réunion fishery has experienced rapid growth and development in all segments (artisan fishery, Antarctic deep sea fishery, longline fishery) for the last five years, in marked contrast to the situation experienced by the huge majority of other European Union fishing communities. The longlining sector, which began five years ago, has shown the most rapid of development. Longlining has, since 1996, not only equalled but overtaken the artisan fishery, with more than 2,300 t production in 1997 and an active fleet of 21 vessels which range from 9 to 33 m long. This fishery targets swordfish (Xiphias gladius) mainly throughout the year, from the equator to 32oS, using deep freeze conservation techniques. The artisanal segment has also shown a rapid extension due to the development of FAD-associated techniques. In the Réunion Island coastal waters (up to 15 miles), there are now more than 30 FADs, exploited by local fishermen from small fishing units with troll and drifting hand lines for scale on the local market.
  • Tuna Data Collection and Processing in Mauritius

    Munbodh, M.; Norungee, D. (IOTC, 1999)
    The Fisheries division of the Ministry of Fisheries and Cooperatives is involved in research, development, management and protection of fishery resources of Mauritius. It is divided into a Fishery Research and Development Service and a Fisheries Protection Service. The latter section is primarily concerned with the protection of fishery resources and enforcement of Fisheries Act. The Albion Fisheries Research Centre (AFRC), established in 1982, comprises the technical services of the Ministry and is responsible for research and development in the fishery sector. Its activities include resource assessment and management, development of fishing technology, fish quality inspection, studies on the marine environment, establishment of marine parks, and aquaculture research.

  • Seaweed diversity patterns in Sub-Saharan Africa

    De Clerck, O.; Bolton, J.J.; John, D.M. (2003)
    A proper understanding of inshore marine ecosystems cannot be obtained without a thorough knowledge of marine vegetation. This paper summarises our knowledge of species diversity patterns of marine macroalgae in Sub-Saharan Africa, highlighting gaps. In Tropical East Africa the seaweed floras of Somalia and Mozambique are not well known. In Tropical West Africa, only a small number of countries are well-collected, although recent advances, including web-based systems, are ensuring that the information which is available can be more easily accessed. South Africa and Namibia have quite well documented seaweed floras, although detailed collections, especially in the subtidal, or detailed studies of taxa, particularly using molecular methods, anywhere in the region are likely to bring up new records and lead to the discovery of species new to science. South Africa has a very rich seaweed flora (ca. 850 species), due to the presence of species from three of the four major biogeographic regions in sub-Saharan Africa occurring within its borders. Figures for reasonably well-studied countries in Tropical East Africa are more than 400 species, whereas much of Tropical West Africa has lower numbers (e.g. 200 species in well-studied Ghana). Factors which may account for these major differences in seaweed diversity patterns are discussed. Training workshops in Africa are necessary to recruit a body of local scientists able to identify and work with seaweeds, and to make the wealth of information in the international literature available to African marine scientists. A network of national herbaria should contain a collection of correctly identified seaweed species.

  • New Sampling and Data Processing Strategy for Estimating the Composition of Catches by Species and Sizes in the European Purse Seine Tropical Tuna Fisheries

    Pianet, R.; Pallares, P.; Petit, Ch. (IOTC, 2000)
    The difficulties associated with tropical tuna sampling strategies, particularly those resulting from the large-scale adoption of the method of fishing on logs, have caused the Indian Ocean tuna scientists concern since the beginning of the purse seine fishery, as well as the ICCAT SCRS (Standing Committee for Research and Statistics of the International Commission for the Conservation of Atlantic Tunas) in recent years. Upon the recommendation of this Committee, in 1996 Spain and France embarked on a European Union project aiming to study the consequences of this new fishing tactic on the estimated catch by species and by size, and to implement a new sampling strategy so as to improve the accuracy of the statistics. Many specific analyses have been necessary because of the complexity of the problem. In this regard, close attention has been given to the influence of different factors (place, time, fishing associations, flags, vessel class, etc.) on the breakdown of catches by species and sizes, the sampling coverage rate, the sample size, the unit of sampling, etc. In this document the results of the different analyses conducted are described and discussed, and a new sampling system for both east Atlantic and Indian Ocean tropical tuna purse seine catch sampling is proposed. This document is mainly focussed on Indian Ocean, while another document (SCRS/97/28) - presented at the last year’s ICCAT meeting – was aimed to the Atlantic Ocean.
  • Cyanobacteria Composition and Impact of Seasonality on their In Situ Nitrogen Fixation Rate in a Mangrove Ecosystem Adjacent to Zanzibar Town

    Kyaruzi, J.J.; Kyewalyanga, M.S.; Muruke, M.H.S. (WIOMSA, 2003)
    To investigate the input of combined nitrogen by cyanobacteria in mangrove ecosystems and the seasonal fluctuation of this biological process, in situ nitrogen fixation activity was measured in day and night experiments carried out at Maruhubi mangrove ecosystem adjacent to Zanzibar town. Sampling was done for 12 months at two stations: Station I covering sandy sediments and Station II muddy sediments. Associated cyanobacteria genera were identified and environmental variables were measured throughout the study period. A total of 10 genera of cyanobacteria were encountered, two of which were the heterocystous cyanobacteria genera Anabaena and Rivularia and eight the non-heterocystous genera Aphanocapsa, Merismopedia, Lyngbya, Microcoleus, Oscillatoria, Phormidium, Schizothrix and Spirulina.....

    Nna Abo'o, P.; Djama, T. (ACP-EU, 1999)
    L’importance du secteur de la pêche dans les pays de l’Atlantique Centre Est n’est plus à démontrer. Au Cameroun, la pêche est à la fois, une source de revenus pour le pays, source d’emploi et contribue à plus de 46% aux besoins nutritionnels des populations en protéines animales.
  • Marine Resources Research Institutions in Mauritius

    Sanders, M.J. (FAO, 1986-03)
    The contents of this document relate principally to a proposal for an autonomous Marine Resources Research Centre in Mauritius. The Consultant concluded that such a Centre lacked Justification at this time. The priority marine resources research was identified as being concerned with fisheries, mariculture and environmental studies (of the lagoon surrounding Mauritius). Most of these activities are already being undertaken within the Fisheries Research and Development Division (Ministry of Agriculture, Fisheries and Natural Resources). It Is proposed that this arrangement continue- but that the Division be re-organized to form part of a broader fisheries department type structure. The additional staff required for the marine resources research and development activities having immediate priority Is identified as at least 23 persons.
