Variation in short-term survival of culture sandfish (Holothuria scabra) released in mangrove-seagrass and coral reef flat habitats in Solomon Islands

The specific aims of our study were: (1) to determine whether cultured juvenile H. scabra released near mangrove–seagrass and coral reef flat habitats suffered different levels of predation, and (2) to identify the predators of juvenile H. scabra and determine whether cages provided short-term protection for released individuals.

Variation in short-term survival of cultured sandfish (Holothuria scabra) released in mangrove-seagrass and coral reef flat habitats in Solomon Islands

Juvenile cultured sandfish (Holothuria scabra) with a mean size of 35.6 F11.4 S.D. were released on soft substrata near mangrove–seagrass and lagoonal coral reef flat habitats in the Western Province of Solomon Islands. Mean survival of H. scabra at the mangrove–seagrass sites was 95–100% 1 h after release and approximated 70% 3 days later. At the coral reef flat sites, however, mean survival was as low as 37.5% 1 h after release and total mortality occurred in two of the three releases within 48 h. Mortality of the juvenile H.

A global protocol for monitoring of coral bleaching

Coral bleaching and subsequent mortality represent a major threat to the future health and productivity of coral reefs. However a lack of reliable data on occurrence, severity and other characteristics of bleaching events hampers research on the causes and consequences of this important phenomenon. This handbook describes a global protocol for monitoring coral bleaching events, which addresses this problem and can be used by people with different levels of expertise and resources.

ReefBase 2.0: a contribution to environmental conservation on a global scale.

The 1997 International Year of the Reef sees the release of ReefBase 2.0: a global database on coral reefs and their resources. It provides the most comprehensive and accessible repository of information to date. Containing information on over 7000 coral reefs in more than 123 countries, ReefBase 2.0 offers an extensive range of time-related data pertaining to coastal tourism, benthic environment ecology, fish population statistics, oceanography, socioeconomics, mariculture, and harvest activities. It also outlines the stresses causing reef degradation as well as management initiatives.

Valuation of coral reef systems: case study of Philippine coral reefs (Taklong Island national marine reserve)

This report is an outcome of a collaborative effort between ICLARM and the University of Philippines - Visayas with funding support from Sida under the project "Valuation and policy analysis for sustainable management of coral reefs". The report summarizes various outputs provided by Taklong Island National Marine Reserve( TINMAR) that directly benefit the coastal communities and other resource users. The biological studies reviewed in the report also indicated that fish biomass has increased which can be attributed to the protection of the area as a marine reserve.

Annual report 2008/09

Along with a feature on our climate change work, this year’s Annual Report covers topics like fish breeding, coral reef work, post-cyclone rehabilitation, big numbers, and helping the most disadvantaged through aquaculture, to name just a few.

Fisheries, trade and utilization of sea cucumbers in Malaysia

Sea cucumber fisheries in Malaysia are exploited off the coastal waters around the coral reef regions in Sabah in East Malaysia. In Peninsular Malaysia, this resource is minimally exploited because more than 90 % of the coral reef islands in both the east and west coasts have been gazetted as marine parks or as fisheries prohibited areas, where fishing activities are prohibited in the vicinity.

Growth of spiny lobster (Panulirus penicillatus) caught off San Vicente, Cagayan, Philippines.

Estimates of growth parameters for male and female Panulirus penicillatus caught in coral reef areas off San Vicente, Cagayan, Philippines are presented. Length-weight relationship parameters are also given. The results indicate that the slope (b) is significantly below 3.0 and does not differ significantly between males and females.
