| During the year under review, attention was focussed on the survey of white shrimp fishery and its mechanisation status in Nigeria. Survey results indicate that at sea, the crayfish beam trawl fishery is all year round, but rough from July to September. Catches are therefore better from October and best between December and June. However, where rains are heavy and early, stow net shrimp fishery at sea is best from January to March. Within the year a series of violent Swells/sourges devastate the Victoria Island beach in Lagos. The preliminary survey of the Institute showed that nourished beach is slightly above the level of the Ahmadu Bellow way. The present low nature of the beach was not adequate enough to absorb the shock impounded by the swell,... |

| Few publications on the Fisheries of Nigeria focus on the non-penaeid decapod stocks, and in general, reports discussing artisanal coastal and estuarine shrimp landings have been based largely on ad-hoc observations. Presumably as a consequence, only the big penaeid Penaeus notialis and Parapenaeopsis atlantica are identified, and that, only occasionally. More often than not, artisanal crustacean catches are usually lumped together as if they consist of a single taxon and treated under such group name as Caridae. The exception is that of Scott (1966) who estimated 1125 tons as the annual landings of filter traps fishing in the Bonny River to Forcados area, about 40kg per man per day. Tracing the abundance of white shrimp Nematopalaemon hastatus,... |

| In view of the ongoing review of IODE, the planned development of an IOC data management strategy and the preparations of the JCOMM strategy it is important that the IODE data and information management community thinks about the prioritization of IODE activities and projects. There are currently a significant number of global and regional projects. Some of these are funded through donors but many require IOC funding. As the funding for IODE for the UNESCO regular programme is not likely to increase it is necessary to reflect on what the international oceanographic community opinion is about IODE. Between 29 October – 3 December 2004 a web-based survey was made available to international oceanographic community around the world.The IOC undertook this... |

| The UN Convention on the Law of the Sea has been signed by a majority of states, and therefore, without any prejudice to the eventual outcome of ratifications, it is prudent for the Working Committee for International Oceanographic Data Exchange to consider the possible effects of the Convention upon its responsibilities and procedures. This note consists of a commentary upon the general principles within the Convention, and is not the official view of the Natural Environment Research Council, the Institute of Oceanographic Sciences, or Her Majesty's Government of Great Britain and Northern Ireland. No legalistic interpretation of the articles of the COnvention is implied or intended. |

| Cette étude, réalisée dans la partie Nord-Est du lac de Bizerte du premier Avril au 30 Juin 1999, porte sur l’étude de l’effet des deux paramètres, distance entre les touffes et poids initial des touffes, sur le rendement de culture par bouturage de Gracilaria verrucosa selon le mode des boudins de sable. Il en ressort que les conditions optimales de culture de cette espèce sont engendrées par un poids initial de 200 g, une distance entre les fragments de thalles de 30 cm et une récolte impérativement vers la fin du mois de Juin. Dans ces conditions, on enregistre un passage du poids de 200 g à 1087 g, un taux de croissance spécifique de 2,20 et une densité finale de 3,74 kg/m². |

| The first phase of a coastal fisheries survey initiated in 1991, with the assistance of the World Bank, was completed in March 1996. The survey found that several inherent parameters are critical to all the main fisheries and these factors severally affect fishing operations. These critical factors include currents as they moderate fish movements and behaviour, lunar cycle, seasonal disruptions, inappropriate improvisation, coastal perturbations, scarcity of fuel wood, menace by trawlers, piracy and increasing costs. Appropriate policies and strategies to redress these critical factors and other disincentives should contribute to evitalising and sustaining small-scale coastal and marine fisheries in Nigeria. The relocation of the institute’s fish farm... |

| M. F. Maury, head of the U.S. Naval Observatory. started to compile meteorological and sea surface data from the logbooks. This allowed him, during the 1840's to expand knowledges in descriptive oceanography. Willing to extend the geographical coverage of his data bank and chartings, Maury wanted to involve merchant navy as well as ships from other nations. This led him to consider favourably projects of universal networks for meteorological data collection such as proposed by the Russian Kupffer in the early 1850's. Maury tried to establish such co-operation when British and US officials came together to uniformize their network. Maury did not succeed to bring the project at an international level. Instead, he only was allowed to call upon an... |
