Community-based stock enhancement of topshell in Honda Bay, Palawan, Philippines
MetadataShow full item record
In Palawan, Philippines, observed reduction of trochus shell resource in various areas was due to unregulated harvest mainly by compressor (hookah) divers and free diving fishers from other provinces. The latter migrate to Honda Bay for greater livelihood prospects (Gonzales, 2004), increasing the population of coastal communities along the Bay. According to fishers in Honda Bay, their shellfish resources were bountiful until traders and divers from other parts of the country came to Palawan in the 1970s, depleting topshell Trochus niloticus and other species. One of the objectives of Coastal Resource Management (CRM) is the regeneration of depleted resources and their sustainable use. On the other hand, the socio-economic objectives are: a) to alleviate poverty in coastal communities through added income and, b) to encourage responsible use of coastal resources through active participation of coastal communities in decision-making, planning, and implementation. The community-based topshell stock enhancement in Barangay Binduyan was assisted by the Fisheries Resource Management Project (FRMP) of the Bureau of Fisheries and Aquatic Resources of the Department of Agriculture (DA-BFAR). The objectives of this paper are to: 1) describe the processes in a community-managed stock enhancement project; 2) document monitoring and evaluation of the project; and 3) give recommendations to improve future community-managed stock enhancement project.

Conference paperT Sugaya - In JH Primavera, ET Quinitio & MR Eguia (Eds.), Proceedings of the Regional Technical Consultation on Stock Enhancement for Threatened Species of International Concern, Iloilo City, Philippines, 13-15 July 2005, 2006 - Aquaculture Department, Southeast Asian Fisheries Development CenterIn the 1960s, the Japanese economy was starting to industrialize. The rapid increase in business investment in new factories and equipment stimulated a yearly economic growth rate of approximately 12% (METI 1970). However, these developments have disrupted coastal landscapes through land reclamation and industrial effluents (Fishery Agency 1980a). Furthermore, overfishing has accelerated with increased consumer spending and demand for fish protein. Consequently, coastal fish resources such as red sea bream (Pagrus major), kuruma prawn (Marsupenaeus japonicus) and swimming crab (Portunus trituberculatus) have been depleted and income of coastal fisherfolk has decreased (Fishery Agency, 1980). Under such conditions, the Japanese government initiated the Stock Enhancement Program in 1963 (Fishery Agency, 1980; Imamura, 1999). The program initially targeted red sea bream and kuruma prawn in the Seto Inland Sea in southern Japan which covers almost 3,000 islands (Imamura, 1999). Because the fundamental concept of stock enhancement programs was to compensate juvenile loss caused by high larval mortality in the ocean, development of mass juvenile production techniques was emphasized (Fishery Agency 1980a; Matsuoka, 1989). Therefore, the release of juveniles became a typical form of stock enhancement in Japan. The current number of target species for stock enhancement has increased to almost 80 species. Stock enhancement is undertaken by both the national government and local governments together with conservation of fishing ground and regulation of fish catches for resource management (Resource Association 1983a; Imamura 1999; Fishery Agency 2000; JASFA 2003a). This article reports the present status of stock enhancement in Japan from the organizational and technical viewpoints.

The Thai Department of Fisheries is breeding some of the endangered species under the “Rehabilitation of Thai Local Fishes and Aquatic Animals Project.” Some of these species are bred for restocking in the wild.
Conference paperNA Lopez - In JH Primavera, ET Quinitio & MR Eguia (Eds.), Proceedings of the Regional Technical Consultation on Stock Enhancement for Threatened Species of International Concern, Iloilo City, Philippines, 13-15 July 2005, 2006 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe paper provides the lists of fisheries related species perceived to be extinct, rare, threatened and endangered as covered under the CITES, IUCN and the Bureau of Fisheries and Aquatic Resources (BFAR)-Fisheries Administrative Order (FAO) No. 208. The listings of freshwater fisheries resources constitute mostly finfishes that are all, except for one, found in the CITES list, the rest under the IUCN red lists and none in the BFAR list. Majority of the listed species are also specific to some areas like Lanao Lake, few in the RINCONADA lakes of Bicol and scarce in some other minor lakes where they are found to be endemic. Most of the indigenous cyprinid species are of commercial value to the locality and are the main source of fish protein in the daily life of the fisherfolk. The listings of marine finfishes constitute mostly sharks and seahorses which are all, except for one, found in the CITES list, the rest under the IUCN Red List and none in the BFAR-FAO list. Although BFAR listed 20 species of whales and dolphins under its FAO 208, marine mammals are not included in this report. Most of the indigenous shark species are becoming rare and extinct due to the rampant shark Status of Threatened Species and Stock Enhancement Activities in the Philippine Fisheries with the rising demand of shark fins smuggled or exported abroad. These marine finfishes are distributed in coastal waters. The listings of marine gastropods, mollusks, crustaceans and echinoderms are all found in the BFAR-FAO listings as Rare, Threatened and Endangered, while few and selective under the CITES and IUCN lists. Accordingly, these are the most common marine resource commodities that are over-exploited, gleaned and gathered illegally, and frequently exported or smuggled out of the country by unscrupulous traders.
