ProjectImproving Management of Coral Reef And Fisheries in Comoros, Kenya, Madagascar, Mauritius and Seychelles - GCP/RAF/520/JPN 2023
Also available in:
The Small Island Developing States (SIDS), but also the coastal mainland countries in the region of Africa, are endowed with extensive coral reefs. These fragile ecosystems have been under the threats of climate change, reef degradation, sand mining, and overfishing, as well as IUU fishing. This is undermining fishery resources preservation, leading to a loss of catches and subsequent revenues for many fishing communities depending on them. As such, this project sought to assist in strengthening the management and conservation of coral reefs and its fisheries as key to enhancing the status of resources in the target countries, stopping the downward trend in production and ensuring long-term sustainable fisheries and resilient communities. -
Book (stand-alone)An Acoustic Approach to Resource Mapping of Pulau Payar’s Coral Reef - BOBP/REP/87 2000
Also available in:
No results found.This document discusses the rationale, the conduct and the results of a new approach — the hydro-acoustic method — tried out to map the reef substrate of four islands at Pulau Payar Marine Park, Kedah state, Malaysia. The decision to adopt the method was taken after an October 1997 workshop held under the Special Area Management Plan of the Pulau Payar project, with support from the Bay of Bengal Programme (BOBP). A private company carried out the reef mapping exercise, whose objective was to document the diversity of coral growth forms at Pulau Payar, map and quantify coral resources, and prepare an update on the coral reef status at Pulau Payar, assessing any damage to the reef. The exercise was carried out in view ofthe plans by the Department of Fisheries, Malaysia, to inventory all the reefs in the country’s islands. Over the years, coral survey techniques have depended heavily on the SCUBA method which is considered risky, time-consuming and costly. Further, i t is impossible to produce a broadscale map with the SCUBA diving method. The author believes that the “new, repeatable and non-destructive hydro-acoustic survey approach” heralds a new era in corat studies. -
Book (series)Estimating reef habitat coverage suitable for the humphead wrasse, Cheilinus undulatus, using remote sensing. 2010
Also available in:
No results found.This study evaluates the use of satellite images for mapping shallow reef areas and the habitat of humphead wrasse. A method for mapping the suitable habitat for adult humphead wrasse is developed based on the location of reef edges on available Landsat images and on the application of a buffer area around the edges, where the probability of finding adult humphead wrasse is highest according to Underwater Visual Survey (UVS) data. The method is used to estimate the habitat coverage of the specie s in Indonesia, Malaysia and Papua New Guinea, three of the most important exporting countries of the species. The total estimated habitat coverage was 11 892 km2 in Indonesia, 941 km2 in Malaysia and 5 254 km2 in Papua New Guinea. The estimates for Indonesia and Malaysia are approximately four times smaller than other available estimates of reef coverage for these countries, the difference being explained by the higher accuracy of the method used in the present study in identifying the location of shallow water fringing reefs. It is concluded that, for the purpose of estimating the suitable areas of humphead wrasse as a basis for defining population size and sustainable export quotas, the results obtained in the present study are more conservative and appropriate than previously available estimates of reef areas.
