Willingness to pay for conserving Layawan watershed for domestic water supply in Oroquieta City, Philippines

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.

Sumilon Island: Philippine marine park pilot site enjoys early success

Since 1974, Sumilon, a 23-ha island near the southeastern tip of Cebu, Philippines, has been managed by Silliman University as a natural reserve in cooperation with the municipality of Oslob, Cebu. The use of the island as a marine park pilot site has been made possible through the Marine Parks Development Program within the Ministry of Natural Resources. This articles gives an account of this pilot project.

Socioeconomic and bioeconomic performance of Philippine fisheries in the recent decades

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.

Reviving the Bais City oyster industry

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.

Response to selection for growth in an interspecific hybrid between Oreochromis mossambicus and O. niloticus in two distinct environments

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.

Overview of sea cucumber aquaculture and sea-ranching research in the South-East Asian region

South-East Asia has traditionally been the global centre of production of tropical sea cucumbers for Chinese markets. Early research into culture methods took place outside this region, notably in India, the Pacific region and China. However, recent investment in Holothuria scabra (sandfish) culture has led to some significant advances within this region. The Philippines and Vietnam have been at the forefront of recent efforts, with involvement from substantial national programs and local institutions as well as international donors and scientific organisations.

Operationalizing the ecosystem approach to small-scale fisheries Management in the Philippines: The Iligan Bay Alliance of Misamis Occidental

This paper describes the application of the participatory diagnosis and adaptive management (PDAM) framework to analyze the governance of small-scale fisheries and the potential for adopting the Ecosystem Approach to Fisheries (EAF) in Misamis Occidental, Philippines. Using the Rapid Appraisal of a Fisheries Management System (RAFMS) as a complementary methodology, the paper provides key information on stakeholders’ perception on scaling-up of fisheries management.
