1. Marine Vertebrates and Low Frequency Sound: Technical Report for LFA EIS - Croll, Donald A.; Tershy, Bernie R.; Acevedo, Alejandro; Levin, Phil
Over the past 50 years, economic and technological developments have dramatically increased the human contribution to ambient noise in the ocean. The dominant frequencies of most human-made noise in the ocean is in the low-frequency range (defined as sound energy below 1000Hz), and low-frequency sound (LFS) may travel great distances in the ocean due to the unique propagation characteristics of the deep ocean (Munk et al. 1989). For example, in the Northern Hemisphere oceans low-frequency ambient noise levels have increased by as much as 10 dB during the period from 1950 to 1975 (Urick 1986; review by NRC 1994). Shipping...

14. Crocodile farming: a multi-million dollar industry - Adan, R.I.Y.
Crocodiles have a long breeding life, which ranges from 25-30 years. There are 27 species and subspecies of crocodiles throughout the world, 18 of which are in danger of extinction, the rest being threatened with declining population due to overhunting and habitat destruction. Two known crocodile species exist in the Philippines: Crocodylus mindorensis (freshwater crocodile) and C. porosus (saltwater crocodile). Killing adult crocodiles, as is being done now, drastically reduces the potential population. Moreover, toxic wastes from mines, destruction of marshes and riverine habitats, and the conversion of their natural habitats for fishponds additionally threaten their populations. Estimates indicate that...

15. Technology for the community: SEAFDEC-designed artificial reefs
An account is given of the fabrication and deployment of artificial reefs used in the SEAFDEC/AQD's Community Fishery Resource Management project, which focused on Malalison Island located in west Central Philippines. The project aimed to apply community-based techniques of fishery resource management through the collaboration of community organizations, biologists and social scientists. The 3 types of reefs (building blocks, concrete pipe culvert, and modified concrete pipe culvert) were deployed at Gui-ob reef covering an area of less than 1 ha.

16. Stock enhancement in Japan and Taiwan - Adan, R.I.Y.
Stock enhancement has been recognized as one of the essential strategies that can sustain and increase the resources of coastal fisheries. It has been practiced for over a century, with more than 100 species released to date in worldwide programs. Among the countries in Asia, Japan and Taiwan have already established the practice of stock enhancement. Details are given of the main species, number or seedstock produced and released in 1996 in Japan. The species released by the Taiwan Fisheries Research Institute 1976-1995 are also described.

17. Establishing a mangrove nursery - Sinohin, Veronica; Baconguis, Santiago
Mangroves play an important role in creating habitats for a diverse community of organisms ranging from bacteria and fungi to fishes and mammals. They grow in intertidal flats, estuaries and offshore islands. In the Philippines, mangrove forests have dramatically decreased in area since the start of the century, and therefore there is a need to reforest. However, first mangrove nurseries must be established since they serve as sources of planting materials for different mangrove species. Furthermore, nurseries would mean a sustainable source of livelihood for coastal communities because of continuous demand for propagules. A brief account is given of procedures...

18. Mangrove community structure survey - Salayo, Nerissa D.; Primavera, Jorge H.; Altamirano, Jon P.
Highlights are given of a mangove community structure survey conducted in the coastal barangays of Carles, Panay Island, Philippines, in April 2003. The survey aimed to qualitatively describe the species composition, community structure and plant biomass of mangrove forests. The 13 sample sites showed a total of 18 mangrove species, dominated by Avicennia marina. The findings, which indicate a modest yet declining diversity of mangroves in Carles, reinforce the need for their protection and management. This is due not only to their importance as habitats for fish and shellfish juveniles that replenish stocks for capture fisheries and aquaculture, but also...
