    • The 1991 Dutch Kenya Expedition

      Heip, C.H.R. (Delta Institute for Hydrobiological ResearchYerseke, The Netherlands, 1991)
      It is proposed to the Dutch Foundation for Marine Research SOZ to organize an expedition to the Kenyan coastal area in 1991. The exact timing of the expedition depends on the availability of the research vessel Tyro. Suitable periods would be December-March (May) and/or September-December. The aim of the expedition in general is to provide basic data on the structure and functioning of marine systems along the East-African coast, and, in particular, to evaluate the ecological effects of the rivers on these marine systems. As a result of human activities, the composition of the riverine water has strongly changed; it is expected that this will have profound effects on the coastal ecosystems. The continental shelf is limited and the ocean becomes very deep close to the Kenyan coast. There is no information on the deeper benthic ecosystems near the coast and also with respect to the pelagic domain only limited information is available: so far it appears that these areas combine a low productivity with a high diversity. In the North, the Somalistream causes strong upwelling during summer. The interactions between the off-shore and coastal areas and the impact of the monsoon on these interactions are unknown. The sedimentology of the East-African coastal zone is unknown as well. The coastal ecosystems in Kenya consist of: (1) coral reefs (fringing reefs) along the entire coastline, with extensive areas of seagrass beds on the more sheltered parts of the backreefs and in lagoonal areas; (2) mangroves on the shores of the brackish parts of rivers and creeks along the coast; also seagrass beds can be found here.

    • 1994 fisheries statistics, Lake Kariba - Zimbabwe shore

      Karenge, L.; Mugwagwa, M.; Muchabaiwa, L.D. (Department of National Parks and Wild Life ManagementKariba, Zimbabwe, 1995-07)
      The report provides catch records for the Kapenta and inshore fisheries in the Zimbabwean waters of Lake Kariba for the year 1994. Kapenta usually constitute about 90% of the total catch from Lake Kariba; for statistical purposes catches are recorded for the 5 hydrological basins - Mlibizi, Binga, Sengwa, Bumi and Kariba. Whereas kapenta represent a unit stock which is harvested by both Zimbabwe and Zambia, the artisanal fishery exploits inshore species which generally occupy water less than 10m deep along the shoreline, considered to be 2 separate stocks. The main species in the inshore fishery are Oreochromis mortimeri, Sargochromis codringtonii, Tilapia rendalli, Labeo altivelis, Hydrocynus vittatus, Mormyrus longirostris, Clarias gariepinus and Synodontis zambezensis.
    • 1994 international beach clean up exercise at the bar beach Lagos, Nigeria.

      Awosika, L.F.; Folorunsho, R.; Isebor, C.; Adegbie, A.T.; Dublin-Green, C.O. (1995)
      At the request of the United States of America Centre for Marine Conservation, the Nigeria Institute for Oceanography and Marine Research organised a beach clean up at the Bar Beach Lagos on September 24 1994. An International beach clean up is usually held on the last Saturday of every September during the COASTWEEK. On this day, volunteers all over the world participate in a beach clean up in an effort to collect data and information on the types and amounts of debri littering the world's beaches. Volunteers for the Bar Beach clean up of 1994 were drawn from all works of life and some Federal and States agencies. A total of 10,872 pieces of different kinds of debri weighing 531.1kg were collected during the clean up. Further analysis of the different debri showed that plastics constituted 37% of the debris collected on the Beach. Other items included paper, which amounted to 16%, metal 3%, foamed plastics, which amounted to 10%, rubber which, amounted to 7%, wooden pieces which amounted to 7%, broken glass which amounted to 7%, and cloth pieces which amounted to 3% of the total debris collected. In all, the data showed that the Bar Beach, which is the most popular tourist beach in Nigeria, is very dirty. The result of this exercise could be useful in the formulation of an effective beach and even coastal zone management policy.
