| The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed... |

| The First ODINAFRICA Training Course on Marine Information Management was held in Cape Town, South Africa, kindly hosted by Marine and Coastal Management at the Research Aquarium, Sea Point. Seventeen out of twenty ODINAFRICA countries were ale to send a participant. The course included theoretical lectures on Information Management as well as a practical hands-on course on the use of the Integrated Library Management System (ILMS) INMAGIC for Libraries which was identified by the IODE Steering Group for the Resource Kit (Miami, March 2001) as a suitable software for this purpose. Discussions were also held on the results of an institutional survey filled by the participants during the course. |

| Guinea coast. It is a shallow expanse of water with restricted circulation in a micro-tidal environment. This aquatic resource of multiple usages receives inputs of domestic The Lagos Lagoon is the largest of the four lagoon systems of the Gulf of hydrocarbon cooling water from a thermal power station and emissions from automobile exhaust. Micro-pollutants examined in the water, sediment and biota have included organic waste, trace heavy metals and chlorinated hydrocarbons. Concentrations detected have identified â hot spotsâ and relatively unpolluted areas for the different contaminants in the lagoon. The results show marked variations and non-uniform distribution from one season to another. It has been difficult to differentiate pollution effects... |

| The diversity and relative species abundance of fisheries resources were studied from Winneba to Cape Coast on the central coast of Ghana during December 2007 to May 2009. Samples of organisms were collected at random from beach seine landings during the study period. The fishes were counted and identified to the family and species levels. Ecological indices such as Shannon-Wiener diversity index, equitability and Sørenson’s similarity index were used to analyse the data. Specimens from Winneba, Saltpond and Cape Coast comprise 56 species belonging to 30 families. Carangidae, Haemulidae, Clupeidae and Sciaenidae were some of the families, where key species occurred during the study. The relative abundance of key organisms in the beach seine landings... |

| Marine reserves are areas of the sea where fishing is not allowed. They provide refuges where populations of exploited species can recover and habitats modified by fishing can regenerate. In some places, closed areas have been used for fisheries management for centuries, and until recently natural refugia also existed, inaccessible through depth, distance or adverse conditions. Developments in technology have left few areas beyond the reach of fishing. Recently, the idea of marine reserves as fisheries management tools has re-emerged, developing from ecosystem management approaches, and observations of incidental fisheries benefits from reserves established for conservation. Marine reserves are predicted to benefit adjacent fisheries through two... |

| This study is an analysis of AGCM model results to understand the dynamics of the response of precipitation over southern Africa (SA) to anomalies in the sea surface temperature (SST) over the Pacific Ocean. The dipole pattern of interannual precipitation anomaly over SA and its temporal variations are quite similar in both the ensemble mean of the control (where the AGCM is forced with observed SST’s in all ocean basins) and experimental runs (where the AGCM is forced with seasonally varying climatological SST over the Pacific Ocean). However the amplitude of the variability is found to be relatively reduced in the experimental runs. This is shown to be a result of the modulation of the Walker circulation by the variability of Pacific Ocean SST. The... |

| Chemical composition of Clarias gariepinus collected from the wild was investigated. The moisture level ranged from 72.2% to 75.7% while the crude protein level was 18.9% to 19.7%.with the mean of 19.3%. The lipid content ranged from 1.04% to 1.32% (wet weight) while ash was 3.05% to 3.7%. The size of the fish did not significantly (p<0.05) affect the proximate composition. The amino acid pattern of different sizes of C. gariepins were similar with lysine level of 7.5 to 8.0g/16gN,and methionine level of 1.56 to 3.08g/16gN. PUFA of C. gariepinus ranged from 6.5to 7.8%. |

| During the intersessional period, the training component of IODE was marked by continuous development and regional expansion. As it was recommended during IODE-XV, the regional approach laid the foundation for IODE-TEMA activities. Centres of excellence for providing regular training were identified in some regions (Japan, Russia). More than 15 short-training courses (usually up to two weeks) were arranged in Japan, Denmark, Thailand, Iran, Russia (Gelendzhik, Obninsk), India, Argentina, Kenya, South Africa, France, Greece, Brazil. During these courses, more than 100 participants received training in oceanographic data management.The programmes of the courses covered different aspects of data and information management and were also used for making local... |

| Typically, coral reefs are dominated by sedentary colonial organisms. Species compositions are temporally and spatially dynamic and populations may be seen to interact through similar mechanisms as those observed in terrestrial plant communities. In these areas, intense competition for limited niche space, selects for varied defensive and offensive strategies and reproductive life history traits. |

| Located just south of the Equator, the Seychelles archipelago is made up of 115 islands scattered over an Exclusive Economic Zone covering an area of 1,374,000 square kilometers, situated to the west of the Indian Ocean between 4 and 9 degrees south of the equator. The total land area is 455 square kilometers (45,250 hectares). Forty-one of the islands are granitic and are all found within a radius of 50 kilometers from the main granitic island. With a land area of 148 square kilometers, Mahe, the main island and seat of the government, constitutes about one-third of the total land area. The remaining 74 islands are coralline, Aldabra being the furthest located 1150 kilometers to the south-west (Figure 1). The country has a unique environment hardly seen... |

| The need to develop capacity in collection, analysis and distribution of data and information from the oceans and all seas was one of the components of Chapter 17 Agenda 21 of UNCED. This was to be done through strengthening of national scientific capabilities for data collection and analysis, creation of national databases, linking of these databases to existing data and information services and mechanisms, and co-operation with a view to the exchange of data and information and its storage and archiving through global and regional data centres. This strategy is perfectly in line with the IODE programme. It has been observed that the participation of IOCINCWIO Member States in IODE programme activities is minimal: no NODCs or RNODCs have been established... |

| A special workshop has been held in Accra, Ghana from 14-18 April 2003 as part of the ODINAFRICAII program for ocean data management. This report describes the content and accomplishments of that special workshop. The workshop programme was based on the IOC OceanTeacher capacity building tool - an extensive collation of documents on marine data, formats, software, program and data management procedures, manuals, protocols, and associated tutorials. A set of intersessional assignments was formulated that included a wide range of specific dataset measures and products that will be assigned regularly through the recently established ODINAFRICA.net communication network. |

| The temperatures of the world’s oceans are increasing at an accelerating rate. Recent estimates indicate that the magnitude of these increases might be as much as several degrees over the next century and undoubtedly, the impacts of these changes on the Earth’s ecosystems are likely to become increasingly obvious. Coral reefs have already shown dramatic responses to the increasing ocean temperatures. Under normal temperature conditions, reef-building corals, which form the foundation of coral reefs, are living very near the maximum sea temperatures that they can tolerate. If they are exposed to even modest increases in sea temperatures, perhaps only 1° C - 2° C, they become stressed and often ‘bleach’. This bleaching of corals is a response to stress, and... |
