The sustainability of domestic water supply from the Layawan Watershed in Oroquieta City critically depends on past and present conservation activities and the availability of funds from stakeholders such as households, communities, non-government organizations, private entities and government agencies. This study determined the willingness to pay (WTP) particularly of households in Oroquieta City to finance conservation projects in Layawan Watershed to ensure the sustainability of domestic water supply.
Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income.
The focus of this paper is on the governance of small-scale or municipal fisheries in the Philippines in light of the critical role they play in the livelihoods of coastal communities and in the nation as a whole. The information and insights presented in this lessons learned brief derive from the project entitled Strengthening Governance and Sustainability of Small-Scale Fisheries Management in the Philippines: An Ecosystem Approach.
The introduction of green mussels (Perna viridis ) is Padre viridis) in Padre Burgos, Philippines, is described. Spat settlement, although small so far, is a strong positive indication that mussel culture is feasible in the area. Upon successful completion of the project, the results will be used to set up guidelines for other sites not yet obtaining spat settlement and also to assist in locating other areas suitable for mussel culture.
The fishing industry in the Philippines was tantamount to a marine capture fishery in the 1950s to 1960s. Aquaculture and inland fishery production were not significant. Only during the 1970s did aquaculture and inland capture fisheries contribute significantly to fish production. From 250 000 t fish production in 1951, this increased substantially to 1.6 million t in the 1990s. An average 4.3% was contributed by fisheries to the gross domestic product from 1988 - 98. Fisheries export earnings reached P12 billion in the 1990s.
An historical account of the establishment of the Silliman University Marine Laboratory is given in this article.
A brief account of the USAID funded fish stock assessment collaborative Research Support Program is given, with emphasis on its Philippine module, devoted to empirical analyses, modelling and field studies aimed at improved management of exploited multispecies fish stocks.
Ifugao lies in the Cordillera Mountains in the north-central part of Luzon. It is famous for its colorful inhabitants, lush forests, crystal waters and magnificent rice terraces. The people have traditionally practiced rice-fish culture. Approximately half the area (total area 8,000 ha) of rice terraces are currently utilized for capture of mudfish (Ophicephalus striatus = Channa striata). There are no data on production of this piscivorous species in Ifugao, but from observations made, it is quite low.
Bais City with its two bays on the southeastern coast of Negros Island is historically the main source of shellfish in Negros Oriental, Philippines. Indigenous oyster species include the large, desirable Crassostrea iredalei (Talaba) and C. malabonensis (Kuko Kabayo) and the small, less desirable C. echinata, C. lugubrius and C. cucullata. Currently the dominant oysters are the smaller less desirable species.
The development of a saline tolerant tilapia strain able to grow fast is of importance in the Philippines, where 240 000 ha of brackish water ponds are available. To this end, founder hybridization between Oreochromis niloticus (with favorable growth traits) and O. mossambicus (with favorable salinity tolerance traits) was performed and followed by backcrossing with O. mossambicus to develop a strain highly tolerant to saline environments. Genetic selection for growth performance was subsequently conducted.
