| Summary, etc. |
This study determined the quality of water and aquatic resources of Mangabol lake during wet and dry season as basis for environmental education. Specifically, it is concerned with the analyses of the quality of water in terms of its physical, chemical and biological characteristics; the aquatic resources in terms of variety of fish and volume of fish catch; the significant difference in the quality of water, and the significant relationship between the quality of water and aquatic resources of Mangabol lake during wet and dry season. Adviser intervention. Data for this study were collected and investigated with the descriptive- comparative method of research (Stangor, 2011) using laboratory analysis to describe the differences in the quality of water and aquatic resources at Mangabol lake during wet and dry season. The physical and chemical characteristics of Mangabol lake met the criteria of DENR for Class C Water Quality for the propagation and growth of fish and other aquatic resources. It is suitable for aquaculture and fishery development. The biological characteristics also fall within the standards during the dry season, however, the values get beyond the standards during wet season. There are 17 varieties of fish harvested at Mangabol lake. These are pantat, tilapia, gele-gele, dalag, carpa, arojo, gurami, tawis, alireg, guramping. ayungin, siringan, alalo, larangan, bonor, bisokol, and beldat. The volume of fish catch in kilograms is greater during the wet season than during the dry season. The quality of water during wet and dry season only differ in depth, turbidity, total suspended solids, salinity, nitrite, chlorophyll-a, total coliform, and fecal coliform. These water quality characteristics are higher during the wet season than in the dry season. The other characteristics such as temperature, pH, dissolved oxygen, and phosphate remain almost the same in both seasons. The water quality depth, turbidity, temperature, total suspended solids, salinity, dissolved oxygen and chlorophyll-a are directly related to the aquatic resources in terms of volume of fish catch during wet and dry season. When the water quality is within the standard for fishery water, the volume of fish catch in kilograms is greater.Although most of the characteristics are way below the criteria, efforts to continually preserve the quality of water and aquatic resources of lake must continue. The maintenance of good water quality does not only depend on the agencies of the government but lies in the hands of the community that benefits from it. In the prevention of the degradation and pollution of the lake, the researcher recommends that proper information dissemination about the present condition of the lake must be undertaken. A brochure containing measures to be carried out in preventing the degradation and pollution of Mangabol lake must be given to the fisherfolks and the farmers at San Gabriel 2d, Bayambang, Pangasinan in order that they apply ecologically sound farming and aquaculture actices. |
