A 106-page guide is a user-friendly presentation of technical botanical description and illustrations of Philippine mangrove species in Panay Island, Guimaras and Aurora Province. Vegetative and reproductive structures of 34 mangrove species that are readily observed in the field are emphasized and presented in color photographs and as graphic icons. Also discussed: importance of mangroves; mangrove decline and legislation; conservation and rehabilitation; and mangrove-friendly aquaculture.

Estuarine, Coastal and Shelf Science, 1998 - ElsevierA total of 4845 penaeids belonging to nine species—Metapenaeus anchistus, M. ensis, M. moyebi, M. philippinensis, Penaeus merguiensis, P. monodon, P. semisulcatus, P. latisulcatus and Metapenaeopsis palmensis—were collected by pocket seine monthly over 13 months from mangrove and non-mangrove sites in Guimaras, Philippines. The restricted distribution of the three dominant species—M. ensisandP. merguiensisto the brackish water riverine mangrove, andM. anchistusto the high-salinity island mangrove and tidal flat—is probably related to different salinity and substrate preferences. Abundance and size composition of the major species suggest a strong nursery role for the riverine mangrove (high juvenile densities, relatively small sizes year-round), limited nursery use of the island mangrove (fewer shrimps, larger size ranges, presence of maturing females) and a non-nursery use (e.g. foraging) in the tidal flat. Penaeid recruitment to the river had two peaks in November and May when the average salinity was ∼20 (Practical Salinity Scale) and water temperatures were high (30–31 °C). The spatio-temporal pattern of penaeid species in Guimaras shows partitioning across habitats and seasonal recruitment influenced by physical and biological factors.

Fish for the People, 2004 - Secretariat, Southeast Asian Fisheries Development CenterAlthough multilateral agencies in Southeast Asia have long been promoting that mangroves, and other wetlands, are wastelands to be put into better use, such as conversion to ponds. However, there is a need for Mangrove Friendly Aquaculture (MFA) technology in the intertidal forest, or swamp, which does not require the clearing of trees. MFA may be defined on 2 levels: 1) silvofisheries or aquasilviculture, where the low density culture of crabs, shrimps and fish is integrated with mangroves; and, 2) mangrove filters where mangrove forests are used to absorb the excess nutrients in the effluents from high-density culture ponds. A review is made of MFA practices belonging to the first category. Discussion is on a country basis, moving from traditional systems in Indonesia, to the introduced technologies in Indonesia, Vietnam, the Philippines and Malaysia. It is hoped that this review will be of use to scientists, aquaculturists, policy makers and governmental/NGOs interested in making aquaculture more ecologically sound and socially responsible.
Aqua-mangrove integrated farming: shrimp and mud crab culture in coastal and inland tidal flats with existing reforested or natural growth of mangroves AT Triño - 2000Throughout the tropics, mangroves are being destroyed at an increasing rate for the development of aquaculture ponds. In the Philippines, for instance, mangroves were about 400,000 to 500,000 ha in 1918 but were reduced to 100,564 ha in 1987. On the average, about 3,500 ha of mangroves are lost every year in the country to accommodate the aquaculture industry (Baconguis et al., 1990). Loss of mangroves means loss of habitat, fishery, income, and livelihood for many coastal inhabitants. The annual catches of major fishing grounds in the Philippines were positively correlated with the areas of existing mangroves (Bagarinao, 1998). Restoration programs of the government such as mangrove reforestation and afforestation were attempted but could not catch up with the unending destruction. An alternative source of income which is directly supportive of resource management was therefore proposed to mitigate ecosystem degradation with the fisher communities in mind. Fishing villages in the Philippines are generally located in the fringes of arable land along coastal plains and are dependent on fishing as a source of income. The common denominator of these villages is the presence of large areas of tidal flats with existing mangroves. To utilize the aquaculture potential of these mangroves, aqua-mangrove integrated farming development projects were introduced to provide alternative livelihood for the fishers in the village. This integrated approach to conservation and utilization of mangrove resource allows for maintaining a relatively high level of integrity in the mangrove area while capitalizing on the economic benefits of brackishwater aquaculture. The projects took off from the concept of co-management, that is, taking into account the partnership between the local community, the local government unit, and the SEAFDEC Aquaculture Department (SEAFDEC/AQD) in the management of the project.
