Coral reefs are widespread along the east African coast and Seychelle islands. Their roles in island building and coastal protection are often underestimated, they are also important fishery habitats and major tourist attractions. The east African marine fishery production, estimated at 1.4-4.9 tonnes per km super(2), is principally a result of artisanal fishing. Siltation, trampling, and destructive fishing methods are the main cause of coral reef degradation along the east African coast and associated islands. Legislation has been implemented to protect coral reefs by establishing marine parks and reserves. However, poaching and anchor damage are widespread on these protected reefs. Legislative provision to increase the benefit to fishing communities may reduce poaching. The establishment of exclusive nature reserves may be one way to ensure preservation of some coral reefs in the region.

ReefBase a global database of coral reefs systems and their resources was initiated at International Center for Living Aquatic Resources Management (ICLARM), Philippines in November 1993. The CEC has provided funding for the first two years and the database was developed in collaboration with the World Conservation Monitoring Centre in Cambridge, UK, as well as other national, regional, and international institutions. The ReefBase project activities and what ICLARM will do to accomplish the project objectives are briefly discussed.

The region's scientists work together to formed the SEACORM Net (Southeast Asia Coral Reef Monitoring Network) for better integration of information and resources. The group intends to establish a strong working relationship between member countries, share information and lessons learnt, inform and update each other on research and monitoring activities in each country, and provide a mechanism for cross-country assistance and collaboration.

The Global Coral Reef Monitoring Network (GCRMN) is an operational unit of the International Coral Reef Initiative (ICRI), established in 1995 and maintained by the Australian Institute of Marine Science (AIMS). The main responsibilities are to provide data and information on the global status of coral reefs, assess how people use and interact with reefs, assist coral reef management, and raise awareness among all stakeholders of the status of reefs and the need for urgent action. It is represented by 17 regional nodes, with overall coordination by a global coordinator based at AIMS.

Two relatively inexpensive light traps to capture pre-settling reef fish and invertebrates are described. A trap made from a plastic bucket (with plastic bottles, a small plastic waste bin and two sheets of plywood) that costs US$15 appears to be just as effective as a large aluminium and plexiglass trap that costs US$275.
