Abstract
Lake Danao is a picturesque inland body of water having an area of 685 ha located in the municipality of San Francisco in Pacijan Island, Camotes, Cebu. At the middle of the lake is a circular islet with an area of one acre. This lake is a potential area for cultivation of fishes in pens and cages. To date there are only two agencies which use the lake for fish production, namely; the Department of Agriculture Regional Office No 7 Carmen-Lake Danao Fishery Complex Research Outreach Station and the CSCST-Fishery and Industrial College, San Francisco, Cebu. The following are the ranges of selected water quality parameters: salinity, 0-0.5 ppt; water temperature, 27-29 °C; pH, 8.5-9. The lake has no definite inlet and outlet of water and is free from pollutants. The water is clear with assorted vegetation. The soil is coarse, silty and sandy. The present study has shown the feasibility of growing tilapia in cages in Lake Danao.

    An environmental assessment of the aquaculture potential of Lake Gawaan, Lake Lenneng and Lake Banao/Danum at the Mt. Province 

    Dang-awan, Rebecca G.; Estima, Martha; Gayagay, Petra; Pagtan, Aida; Ramos, Ma. Abegail A. (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 Resources, 2001)
    This study reviews the existing conditions of the three Mt. Province lakes: Lake Gawaan, Lake Lenneng and Lake Banao/Danum. Three mechanisms were employed. First is the overview of the resource capabilities. This includes the geographical, physical and biological characteristics, as well as the identification of nearby communities and the possible market distribution channels. The physical characteristics are the watershed type, color of water, kind of shoreline, source of water, water fluctuation levels and transparency/turbidity. Biological and chemical characteristics comprise the primary productivity, dissolved oxygen, nitrate, pH, ammonia, and stock availability (catch composition, gear type, seasonal distribution and production rate). The second mechanism is the understanding of the limitations of the area and development prospects which could cater to the needs of the growing population. This tackles suitable aquaculture practices that may be adopted at the areas concerned in order to increase fish production at the Mt. Province. The last mechanism is to determine if the combined efforts of the non-government organizations, government agencies and other concerned groups could be improved to prevent a piece-rate resource development program. Results showed that favorable conditions for fish culture are present in the three lakes. Culture of fish in net cages and pens appears suitable for the lakes.

    Assessment of local government's implementation of open access policy in Taal Lake, Philippines: Effects on lake conservation and management 

    Mercene-Mutia, Ma. Theresa (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 Resources, 2001)
    The effects of local government's implementation of the current national policy on open access in municipal fisheries are assessed in terms of their impact on the fishery resources of Taal Lake. Local officials and fisherfolk were interviewed and their responses were analyzed for trends in perceptions on how local open access policies affect fishing practices and productivity in the lake. A policy matrix containing certain areas of concern of local governments related to sound decisionmaking on lake fishery was designed. The study shows that local government implementation of open access policy in Taal Lake tends to have negative effects on the lake's fisheries. Open access allows for the unregulated entry of fishing practices like fish cage culture which tend to increase the pollution load in the lake. Pollution due to fish farming in cages seems to even exceed loads from domestic wastes and agricultural runoff. While fish cages flourished in the lake, the income of small fisher folk has declined because of dwindling catch from capture fisheries. It is recommended that national government agencies (e.g., Department of Agriculture, Bureau of Fisheries and Aquatic Resources, Department of Environment and Natural Resources) should forge an agreement with local government units for a continuing assessment of the fishery resources in Taal. This needs to be coupled with technical assistance to undertake sustained efforts to improve the conservation, productivity and management of the lake's aquatic resources. There is also a need to increase the budgetary allocations for new research and extension activities to address problems and issues of the fishery sector in the lake and for upgrading the capability of local and sectoral policy and decision makers on the lake's fisheries.
