lagoons will be studied to determine the degree of coral reef degradation resulting from the 1998 bleaching event. Researchers: S. Mwachireya, J. Uku & P. Wawiye Project 4. Fisheries – Coral reef fisheries Artisanal fisheries catch statistics and socio-economic surveys of fishermen will be conducted to investigate nay long-term effects of coral mortality on fisheries, and of the awareness of fishermen of potential impacts. The project will be linked with similar CORDIO projects in South Asian and the Indian Ocean Islands. Researchers: D. Obura & G. Mwatha TANZANIA Country co-ordinator: Christopher Muhando Institute: Institute of Marine Science, University of Dar es Salaam 1. Extent of coral mortality at selected sites in Tanzania The extent of coral mortality is to be determined and permanent monitoring stations established at several sites along the coast of Tanzania. As much as possible, monitoring will be conducted in collaboration with local research, mangement and/or conservation instutitions. Co-ordinator: Christopher Muhando Institute: Institute of Marine Science Collaborating institutions: Fisheries Department, Tanga Coastal Zone Management Project, Mafia Island Marine Park, Frontier Tanzania 2. Determining the socio-economic impact of coral bleaching and mortality in Tanzania The impact of the 1998 coral mortality on coral reef resource users will be investigated using informal and formal survey methods, focusing on the fisheries and tourism industries. Socio-economic survey tools developed for South Asia through other CORDIO activities will be incorporated for comparison around the region. Co-ordinator: Narriman Jiddawi Institute: Institute of Marine Science 3. Individual study projects – Changes in the competition between hard corls and sea anemones (corallimorpharia) following the 1998 coral mortality. Past studies have shown that on degraded reefs, sea anemones (especially Rhodactis spp.) can outcompete corals to dominate reef surfaces. This study will investigate if reefs degraded due to the 1998 bleaching will become dominated by sea anemones and how this may relate to past findings. Researchers: B. Kuguru, E. Mbije & C. Muhando Institute: Institute of Marine Science MOZAMBIQUE Country co-ordinator: Helena Motta Institute: Ministry for Co-ordination of Environmental Affairs (MICOA) 1. Preliminary assessment of coral bleaching in Mozambique Rapid assessment surveys were conducted along the entire coast of Mozambique in March/April 1999 to determine the impacts of the 1998 El Niño on coral bleaching and mortality. Coral bleaching and mortality were significant, on average 30–80% of the corals at any single site. Suitable permanent monioring sites and training needs were identified for further CORDIOrelated activities. Co-ordinator: Helena Motta Institute: Ministry for Co-ordination of Environmental Affairs (MICOA) 2. Training and establishment of permanent coral reef monitoring sites in Mozambique The training of research officers and graduate students in coral reef monitoring techniques was identified in (1) as a priority activity to build national capacity for – 91 –
monitoring and establish a human resource base for development of research activities on coral reef issues. The training course is scheduled for September 1999, followed by establishment of monitoring sites by course attendees. Funding: These activities will be covered by MICOA, with support from CORDIO through participation of the East Africa Co-ordinator and generalization of course structure and materials for use elsewhere in the region. Co-ordinator: Helena Motta Institute: MICOA Collaborating institutions: CORDIO and Dr Michael Schleyer, Oceanographic Research Institute, South Africa – 92 –
