Some limnological features of the northern shore areas of Volcano Island, Lake Taal
MetadataShow full item record
Physico-chemical and biological features of the northern shore areas of Volcano Island, Lake Taal observed at monthly intervals from four stations during the period 1994 and 1996 indicate varied microhabitats inhabited by a variety of plants and animals. Physico-chemical characteristics of surface waters were: temperature, 28-35°C; dissolved oxygen content, 3.5-6.2 ppm; pH, 7.5-8.9; salinity, 0-24 ppt; and conductivity, 1.6-4.3 S cm-1. Substratum types were mainly sandy with pebbles or rocks or sandy-muddy. Characteristic submerged plants were the eelgrass Vallisneria gigantea and filamentous green algae. In the eelgrass region, atyid shrimps, mostly Ciridina gracilirostris, commonly occur. Snails such as Melanoides costellaris and Terebia granifera were the most abundant benthic animals collected. Other invertebrates identified from core samples were Corbicula manilensis, annelids, crustaceans and chironomid larvae.

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.
Conference paperRR Platon - In Conservation and Ecological Management of Philippine Lakes in Relation to Fisheries and Aquaculture: Proceedings … Seminar-Workshop held on October 21-23, 1997, INNOTECH, Commonwealth Ave., Diliman, Quezon City, Philippines, 2001 - Aquaculture Department, Southeast Asian Fisheries Development Center; Philippine Council for Aquatic and Marine Research and Development (PCAMRD), Department of Science and Technology; Bureau of Fisheries and Aquatic ResourcesSince 1976 the Aquaculture Department of the Southeast Asian Fisheries Development Center (SEAFDEC/AQD), through its Binangonan Freshwater Station has been continuously involved in research on various aspects of inland waters, with emphasis on Laguna de Bay. Lakes Paoay, Taal, Sampaloc and Naujan have also been studied to a limited extent. Research efforts focused on monitoring activities of various biological and physico-chemical parameters in the lake; pollution studies; improvement of practices towards an environmentally sound and sustainable aquaculture enterprise; socio-economic impacts of aquaculture on lakeshore communities and other related activities. The Department has been actively collaborating with various national and international agencies as well as non-government organizations in its effort, to improve its research capabilities. The research results have been published in both local and international scientific journals and proceedings.
