Title: Technical publication of Nigerian Institute for Oceanography and Marine Research (NIOMR) Lagos Nigeria Authors: Ayinla, O. A. Abstract: The Nigerian Institute for Oceanography and Marine Research (NIOMR) established in November 1975 by the Research Institute Establishment Order of 1975 has the responsibilities to conduct research into the resources and geological/geophysical, chemical and physical characteristics of the Nigerian territorial waters and the high seas. NIOMR also conducts research to fish utilization as well as Extension and Liaison Services. Since the establishment of NIOMR, a total of 35 occasional papers and 109 technical papers had been published to expose the research findings of the Institute to various stakeholders. These technical papers were previously published as standalone papers. In order to improve the quality, publication and circulation of scientific information from the Institute NIOMR’s Technical Committee was set up in June 2007. I am happy to note that the new Technical Publication Committee has coordinated the publication of this new NIOMR Technical Paper Series as volumes. Each Volume which may consist of 5 or more papers will be subsequently published on a half yearly basis. The papers in this new series have been critically peer reviewed both internally and by external scientists. I hope that with the release of this maiden technical paper series, NIOMR scientists will seize the opportunity to make their research findings available to the scientific community, educational, government and private stakeholders. It is my believe that this publication and subsequent editions, will further extend the frontiers of knowledge and contribute to the body of scientific information needed for the socio-economic development and sustainable management of Nigeria’s marine coastal environment and resources.

Title: Marine biodiversity in Nigeria – the known and the unknown Authors: Isebor, C. Abstract: Nigeria has a coastline of 853 km, a maritime area of 46,500 km2 and an exclusive economic zone of 210,900 km2. The Nigerian coastal area is hot and humid, with an annual temperature range between 26 and 34oC, and the highest temperatures occurring during the dry season (November to March). The total annual rainfall averages between 350 and 600 centimeters. More than 80 percent of the rain falls during the rainy season (April to October) when tropical storm conditions are frequent. Rainfall is usually heavy and occasionally lasts for over 24 hours. Rainfall of about 50mm/hour between July and August are common and results in flash floods. The predominant wind is the rain bearing southwest trade wind from the Atlantic Ocean. During the short dry period, the dust laden north east dry wind from the Sahara desert reaches the coastal areas, producing hazy conditions (Ibe et al. 1985). The Nigerian intertidal mangrove swamps cover an area of about 5,590 square kilometres (Allen 1965). The swamps are separated from the sea by barrier-bar islands that are usually broken by tidal channels. The Niger delta area, which has a flourishing mangrove ecosystem, was formed by long and continuous interactions of sediment laden Niger River water and coastal processes, creating beach-ridges, barrier islands, a fresh water floodplain and brackish mangrove swamp. This coastal habitat is interrupted by a series of estuaries, lagoons and embayments. The total brackish water habitat is estimated as 12,900 km2. The mangroves, wetlands and inter-tidal systems occur in saline soil subject to tidal inundation and occupy a total area of almost 1 million hectares (Okigbo 1984, FAO 1981). Fishing is the main occupation of the coastal communities, with various types of gears being employed. Fishing is conducted in creeks, rivers, estuaries, mudflats, near-shore and offshore. Commercial fishing supports about 440 trawlers, with about three quarters of the fleet targeting the shrimp resources. The mangrove plants and associated halophytic plants are used for building, extraction of tannin; construction works, curing of fish, and other fishing implements. Mineral resources in the coastal and marine waters include petroleum, with an oil reserve of about 21 billion barrels and gas reserve estimated at more than 11 trillion cubic feet. Current production levels are at about 1.9 million barrels of crude oil and 200,000 barrels of gas condensate per day. The current natural gas production is 3,400 million cubic feet per day in the form of associated gas, of which about 340 million is marketed in the domestic market, 340 million re-injected and 2,720 million cubic feet is flared daily. Sand and gravel are exploited onshore and offshore, in the riverbed, lagoons, estuaries and beaches. Millions of cubic meters of sand are dredged annually during oil exploration and exploitation, as well as for the construction industry. Most of the sand mined is used for reclamation of swampy areas, in the block-making industry and construction work.

Title: Nigeria institute for oceanogaphy and marine research annual report 1999. Authors: Ajayi, T.O. Abstract: The Institute succeeded in realising part of its long-term plan of extending its research activities to cover the entire coastline of Nigeria, with the opening of Sapele Rural Station in Delta State. The station had since commenced operation prioritising farmers' field test and incubation of NIOMR's validated research results and technologies An attempt was made to revitalise the work force through staff upgrading, promotions, confirmation of appointments and retirement from the service. I n all 103 officers in various cadres were affected. New postings were also effected during the year for more effectiveness.All-year-round statistical sampling of landings in the industrial fishing sector continued throughout 1999. Croakers, as usual, dominated the fish trawls being, the most abundant commercial species in inshore waters, accounting for 84.14 % of landings. Size statistics during the year showed definite pressure on inshore fisheries resources. This calls for long term management for sustainability.Preliminary analyses of the trawl survey of the Gulf of Guinea conducted during the year indicated that while bigeye (Brachydeuterus auritus) occurred in varying quantities in the entire gulf region, certain other species were location specific.In response to the US ban on Nigeria's shrimp exports to protect turtles which are on the endangered species list, but are caught incidental to shrimping, NIOMR researched and developed the Turtle Excluder Devices (TED) much earlier on, thereby persuading US authorities to un-proscribe Nigeria. In 1999, NIOMR hosted on behalf of the Federal Department of Fisheries, the FAO/GEF Workshop on Trawl Shrimp Fishery Big-catch Reduction Workshop for the African Region.Drawing participants from Cameroon, Tanzania, Gambia, Ghana, Seychelles, Mauritius and Senegal among others, the workshop prepared project proposals for large scale fishing under the Global Environmental Fund (GEF) to address trawl shrimp fishery by Catch.Significant progress was made in integrated aquaculture practices at the out- station Badore confirming the economic viability of fish-cum vegetables (Ugu) propagation. Projections from field practice suggest that one hectare of farmland can generate as much as N400, 000.00 gross revenue per annum from just Ugu alone.In view of the commercial importance of fish culture in Nigeria, efforts were made during the year to isolate highly productive strains of catfish Clarias garieQinus bio-technically, for development into base broodstocks. In the meantime, infrastructures and logistics were put in place for the institutionalisationof the packaged 12-week intensive aquaculture training programme conceptualised entirely at NIOMR for fish farm entrepreneurs' capacity building. Hopefully funding will improve in year 2000 so that appropriate attention can be devoted to Aquaculture, which clearly holds the key to self-sufficiency in fish production.Poor mass dissemination and extension of farm technologies was identified as a bottleneck to the rapid development of the Nigerian agriculture. NIOMR fielded a Fisheries Extension Technologies Workshop in 1999 to firm up the strategies for a viable and effective Fisheries Extension Framework in Nigeria.Although the Chemical and Physical Oceanography programme was handicapped by the non-serviceability of Research Vessel "SARKIN BAKA" previous data collections were analysed for military application. NIOMR continued to participate in International workshops and discourses on these matters. NIOMR was elected a Vice-Chairman for the Intergovernmental Oceanographic Commission (IOC of UNESCO) with responsibility for capacity building.NIOMR was nominated member of an Inter-Ministerial Committee on the permanent Solution to the Bar-Beach Erosion Problem. In addition the Geology/Geo-physics Division of NIOMR was involved in the CSI (UNESCO) specially funded project on the runoff drainage systems of Victoria and Ikoyi Islands in Lagos.The main tool for oceanographic research work, the "SARKIN BAKA" awaited more funds in 1999 to get into the final phase of its NIOMR concretised its out reach programmes in 1999 and work on NIOMR/Shell Petroleum Development Company really took off in November 1999. Earlier in the year, SPDC started negotiations on another collaboration with NIOMR on their Forcados Integrated Plant project. NIOMR opened up communications with the Bayelsa State Government on the introduction of NIOMR's Fish Drying Equipment to the State. In 1999, NIOMR vigorously invested in computerisation and added a total of 24 desk tops to the stock and arrangement for internet conclusively were far advanced. Staff training and retraining were areas of high priority refurbishment.NIOMR concretised its out reach programmes in 1999 and work on NIOMR/Shell Petroleum Development Company really took off in November 1999.

Procurement of plastic chairs will complete the up grade systems.It is hoped that year 2000 funding levels will improve tremendously, commensurate with the challenges at hand. T. 0.
