Development and conservation of Philippine mangroves: institutional issues
(Elsevier, 2000)
The decline of Philippine mangroves from half a million hectares in 1918 to only 120 000 ha in 1994 may be traced to local exploitation for fuelwood and conversion to agriculture, salt beds, industry and settlements. But ...
Are mangroves worth replanting? The direct economic benefits of a community-based reforestation project
(Cambridge University Press, 2006)
Competition for coastal land use and overexploitation have reduced or degraded mangrove coverage throughout much of their distribution, especially in South-east Asia. Timber production was the initial motivation for early ...
Ethnobiology, socio-economics and management of mangrove forests: A review
(Elsevier, 2008)
There is growing research interest in the ethnobiology, socio-economics and management of mangrove forests. Coastal residents who use mangroves and their resources may have considerable botanical and ecological knowledgeable ...
A review of mangrove rehabilitation in the Philippines: successes, failures and future prospects
(Springer, 2008)
From half a million hectares at the turn of the century, Philippine mangroves have declined to only 120,000 ha while fish/shrimp culture ponds have increased to 232,000 ha. Mangrove replanting programs have thus been ...
Seasonal abundance, distribution and recruitment of mud crabs (Scylla spp.) in replanted mangroves
(Elsevier, 2006)
The abundance and distribution of mud crabs were studied in a replanted mangrove forest in Buswang, Aklan, Philippines. Two fishing gears, lift nets and bamboo traps, were used to monitor relative abundance of Scylla spp. ...
Effect of aquaculture on world fish supplies
(Nature Publishing Group, 2000)
Global production of farmed fish and shellfish has more than doubled in the past 15 years. Many people believe that such growth relieves pressure on ocean fisheries, but the opposite is true for some types of aquaculture. ...
Baseline assessment of fisheries for three species of mud crabs (Scylla spp.) in the mangroves of Ibajay, Aklan, Philippines
(University of Miami, Rosenstiel School of Marine and Atmospheric Science, 2007)
Stock enhancement through habitat restoration and habitat release have both been considered as approaches to the management of declining Scylla spp. Prior to stock enhancement trials, the present study was conducted to ...
Size and diel differences in activity patterns of Metapenaeus ensis, Penaeus latisulcatus and P. merguiensis
(Taylor & Francis, 2000)
The nursery function of mangroves as shelter has been postulated to explain the positive correlation between shrimp catches and mangrove area. This study was undertaken to document shelter use and other activities in ...
Collection of the clam Anodontia edentula in mangrove habitats in Panay and Guimaras, central Philippines
(Kluwer Academic Publishers, 2002)
The mangrove clam Anodontia edentula is highly prized in the Philippines for its flavor and large size. Because this infaunal species is found down to one meter deep in mangrove areas, harvesting the clam reportedly damages ...
Coastal ecosystem-based management with nonlinear ecological functions and values
(American Association for the Advancement of Science, 2008)
A common assumption is that ecosystem services respond linearly to changes in habitat size. This assumption leads frequently to an “all or none” choice of either preserving coastal habitats of converting them to human use. ...
