Limnology of Lake Wood: an Ancestral Lake of the Subanen Tribe
Philippine Journal of Science 150 (5): 1231-1243, October 2021 ISSN 0031 - 7683 Date Received: 14 Dec 2020 Limnology of Lake Wood: An Ancestral Lake of the Subanen Tribe Marjohn Y. Baludo1*, Rey Donne S. Papa3, and Francis S. Magbanua2 1Institute of Environmental Science and Meteorology; 2Institute of Biology University of the Philippines Diliman, Quezon City 1101 Philippines 3Department of Biological Sciences, College of Science; and Research Center for the Natural and Applied Sciences and the Graduate School University of Santo Tomas, Manila 1015 Philippines Relatively limited information exists on Lake Wood’s limnology and ecology, an ancestral lake of the Subanens. Here, we provide a limnological characterization of the lake – exploring its physical, chemical, and biological features. The data on lake morphometry were gathered using an echosounder; lower depth water samples were collected using a Niskin water sampler for physicochemical analyses while surface water samples were collected at five sampling sites for phosphate (PO4) analysis; and zooplankton samples were collected at several depths through vertical towing in March–April 2019. Lake Wood, located at 320 m above sea level, has an extensive surface area covering 7.38 km2 with a maximum depth of 85 m. Lake water comes from rainfall, small rivers, and groundwater and empties into the Dumanquilas Bay via its only outlet – the Biswangan River. Land use of the lake is predominantly cultivated land. Moreover, based on the trophic state index (TSI), the lake’s current trophic status is eutrophic. During the study periods, thermocline and oxycline formed at 15 m below the surface of the lake. -

(033) 320-0908, E-mail: [email protected]; [email protected]; ABSTRACT: Lake Lanao is one of the ancient lakes in the world and the second largest lake in the Philippines. At present, the lake is considered pristine, however, the biodiversity potential of the lake is now being threatened by various human activities such as the discharge of wastes from municipal sewers. Municipal sewage contains human faeces and water contaminated with these effluents may contain pathogenic (disease-causing) organisms and consequently, may be hazardous to human health if used as drinking-water or in food preparation. Meranao, the local dwellers of the lake depend largely on this body of water as their source of food and drinking water. Hence, the present study evaluates the water quality of Lake Lanao using microbiological analyses specifically along with five municipalities: Tamparan, Taraka, Wato-Balindong, Tugaya, and Bacolod-Kalawi Lanao del Sur. The study was conducted for three months of sampling periods. Findings showed the presence and the estimated number of coliform bacteria that may be associated with the occurrence of waterborne diseases in the surrounding municipalities. Keywords: Microbiological analyses, Water quality, Environmental monitoring, Lake Lanao I. INTRODUCTION gain awareness on the present condition of the lake and Lake Lanao is one of the most important inland body of water consequently, enlighten the local residents as to how human in the Philippines. -

Geometric Morphometric Analysis of Body Shape Variation Among And
Research Journal of Fisheries and Hydrobiology, 5(1): 44-51, 2010 © 2010, INSInet Publication Body Shape Variation Between Two Populations of the White Goby, Glossogobius giuris (Hamilton and Buchanan) 1Sherwin S. Nacua, 2Emma L. Dorado, 3Mark Anthony J. Torres and 3Cesar G. Demayo 1Biology Department, MSU, Marawi City; 2Notre Dame of Marbel University, Koronadal City, South Cotabato; 3Department of Biological Sciences, MSU-IIT, Iligan City, Philippines Abstract: The major objective of this study is to determine the body shape variation among and between the two populations (Lake Lanao and Lake Buluan) of Glosssogobius giuris (Hamilton and Buchanan), using landmark-based geometric morphometrics. A total of 33 specimens from Lake Lanao (17 males, 16 females) and 31 from Lake Buluan (16 females, 15 males) were examined. Nineteen landmark points were digitized on the specimens from which relative warp scores were derived. Discriminant function analysis showed that both populations exhibit sexual dimorphism. Body shape between the two populations also shows significant difference, with Lake Lanao gobies having bigger head aspect ratio (low) and mouth with a narrower body and more elongated dorsal and anal fins. These characteristics are suggestive of a more efficient carnivore with a more active habit or a fast flowing environment for Lake Lanao gobies. Key words: landmark-based geometric morphometrics, Procrustees distance, relative warp analysis INTRODUCTION freshwater fishes, among them the White Goby, Glossogobius giuris (Hamilton and Buchanan). Exposed to different environmental conditions, The White Goby is a freshwater fish that lives in fishes, like all organisms are capable of making freshwater but spawns in seawater. It is widely adaptations to enable them to survive. -
Aquaculture Practices and Their Impact on Philippine Lakes
Aquaculture Practices and Their Impact on Philippine Lakes Dennis B. Araullo Bureau of Fisheries and Aquatic Resources Quezon Avenue, Quezon City Araullo DB. 2001. Aquaculture practices and their impact on Philippine lakes, pp. 25-28. In CB Santiago, ML Cuvin-Aralar and ZU Basiao (eds.). Conservation and Ecological Management of Philippine Lakes in Relation to Fisheries and Aquaculture. Southeast Asian Fisheries Development Center, Aquaculture Department, Iloilo, Philippines; Philippine Council for Aquatic and Marine Research and Development, Los Baños, Laguna, Philippines; and Bureau of Fisheries and Aquatic Resources, Quezon City, Philippines. 187 pp. Introduction The rapid progress and development in the aquaculture sector during the past years has made an important contribution to the overall fish production in the Philippines. In 1996, 35.4% of the total fish production or 980,857 mt came from the aquaculture sector. Although milkfish from brackishwater ponds comprise the bulk of the produce, tilapia production from freshwater aquaculture in lakes, ponds and reservoirs is increasing annually. Fish cages and fish pens proliferate in most inland waters. The operation of such structures as livelihood for the coastal inhabitants has been recognized as a profitable venture. Many have gone into tilapia culture in ponds and small experimental cages in lakes and reservoirs in the 1980's. The success of tilapia culture in cages in the Bicol Region and Magat Dam in Isabela triggered the interest of other enterprising businessmen to expand the practice to other inland waters. However, problems of mass fish kill caused by deteriorating water quality have been reported. There is a need to strictly regulate the aquaculture practices; otherwise, more problems in the aquatic environment will be encountered. -
The Status of Philippine Lake Studies: Scholarly Deficit in Social Science and Small-Lake Research
Asia-Pacific Social Science Review 15 (1) 2015, pp. 78-101 The Status of Philippine Lake Studies: Scholarly Deficit in Social Science and Small-Lake Research Bing Baltazar C. Brillo University of the Philippines Los Baños, Philippines [email protected] This study surveys the literature on Philippine lake studies using a representative sample from the library databases of the three leading universities in the country. The paper proceeds as follows: firstly, it categorizes the existing lake studies by scholarly orientation (natural science perspective or social science perspective) and by physical size of the particular lake under study (big lake or small lake); secondly, it charts and assesses the overall trajectory of lake studies in the country. The paper concludes that Philippine lake studies are dominated by the natural science-based studies and heavily concentrated on big-lake research. This finding illustrates the gaps in the literature, specifically: one, the need to account for all the existing lakes in the country; two, the need for more social science-based studies on lakes; and three, the need for more outputs on small-lake research. The paper closes with the call to balance scholarly deficit as the way towards meaningful progress in lake studies in the country. Keywords: Philippine Lakes, Small-Lake Studies, Big-Lake Research, Lake Studies, Natural Science, Social Science and Lake INTRODUCTION day modern societies, lakes—natural or artificial reservoir —have catered to human needs, from Lakes are important! This statement is rudimentary uses (such as drinking water, supported by the fact that over 90% of the source of food, and transportation) to more liquid freshwater on the earth’s surface is sophisticated utilization (such as agricultural contained in lakes (Shiklomanov, 1993; irrigation, fish farming, flood control, and International Lake Environment Committee hydroelectric power). -

In CB Santiago, ML Cuvin-Aralar and ZU Basiao (eds.). Conservation and Ecological Management of Philippine Lakes in Relation to Fisheries and Aquaculture. Southeast Asian Fisheries Development Center, Aquaculture Department, Iloilo, Philippines; Philippine Council for Aquatic and Marine Research and Development, Los Baños, Laguna, Philippines; and Bureau of Fisheries and Aquatic Resources, Quezon City, Philippines. 187 pp. Abstract Geographically located in Central Mindanao, Lake Lanao is the second largest lake in the Philippines. The lake is famous locally for its various uses and internationally for its endemic cyprinids. This paper intends to inform the local leaders and the national planners about Lake Lanao's dwindling fisheries resources, the extinction of some endemic cyprinids, and the current interventions as well as suggested action plans to increase fish production and to conserve the remaining species in the lake. The past and present studies on the lake are also reviewed. Early and latest statistics on the lake's fisheries production are presented to invite the interest of all sectors in coming up with the integrated approach to protect, conserve and increase its fisheries production. Local and national interventions to conserve and increase fisheries production are discussed. These include the setting up of BFAR Fisheries Station in Kialdan, Marantao; the establishment of a fish hatchery in Poona, Marantao by Southern Philippines Development Authority; the formation of Save Lake Lanao Movement by the local leaders; the creation of Lake Lanao Research and Development Council; the current concern of Philippine Council for Aquatic and Marine Research and Development-DOST; and the extension and research and development thrusts of the Mindanao State University, College of Fisheries in Marawi City.
