GUIDE TO THE CLASSIFICATION OF FISHING GEAR IN THE PHILIPPINES By AGUSTIN F. UMALI, Ichthyologist Illustrations by Silas G. Duran RESEARCH REPORT 17 Fish and Wildlife Service, Albert M. Day, Director United States Department of the Interior, Oscar L. Chapman, Secretary UNITED STATES GOVERNMENT PRINTING OFFICE : 1950 For sale by the Superintendent of Documents, United States Government Printing Office Washington 25, D. C. - Price 40 cents ABSTRACT One of the serious handicaps in the administration and manage ment of the fisheries of the Philippines has been the lack of standardized nomenclature for fishing gear. This publication attempts to solve the problem. It is divided into five parts: The first presents a basic clas sification of fishing gear; the second is a key by means of which fishing gear can be identified and new terms for fishing gear can be properly classified; the third defines and illustrates various types of fishing gear; the fourth is a tabular classification of local Filipino di alect names; and the fifth is a glossary including definitions of more than a thousand terms.

Systematic Taxonomy and Biogeography of Widespread
Systematics and Biogeography of Three Widespread Australian Freshwater Fish Species. by Bernadette Mary Bostock B.Sc. (Hons) Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Deakin University February 2014 i ABSTRACT The variation within populations of three widespread and little studied Australian freshwater fish species was investigated using molecular genetic techniques. The three species that form the focus of this study are Leiopotherapon unicolor, Nematalosa erebi and Neosilurus hyrtlii, commonly recognised as the three most widespread Australian freshwater fish species, all are found in most of the major Australian drainage basins with habitats ranging from clear running water to near stagnant pools. This combination of a wide distribution and tolerance of a wide range of ecological conditions means that these species are ideally suited for use in investigating phylogenetic structure within and amongst Australian drainage basins. Furthermore, the combination of increasing aridity of the Australian continent and its diverse freshwater habitats is likely to promote population differentiation within freshwater species through the restriction of dispersal opportunities and localised adaptation. A combination of allozyme and mtDNA sequence data were employed to test the null hypothesis that Leiopotherapon unicolor represents a single widespread species. Conventional approaches to the delineation and identification of species and populations using allozyme data and a lineage-based approach using mitochondrial 16S rRNA sequences were employed. Apart from addressing the specific question of cryptic speciation versus high colonisation potential in widespread inland fishes, the unique status of L. unicolor as both Australia’s most widespread inland fish and most common desert fish also makes this a useful species to test the generality of current biogeographic hypotheses relating to the regionalisation of the Australian freshwater fish fauna. -

Quilang1,2* 1Natural Sciences Research Institute, University of the Philippines Diliman, Quezon City 1101 Philippines 2Institute of Biology, College of Science, University of the Philippines Diliman, Quezon City 1101 Philippines 3Institute of Human Genetics, National Institutes of Health University of the Philippines Manila, 625 Pedro Gil St., Ermita, Manila 1000 Philippines The molecular phylogeny of the Philippine tigerperches is first described in this study. Eight species were analyzed: these include one endemic species (Leiopotherapon plumbeus); one introduced species (Bidyanus bidyanus); and six native species (Terapon jarbua, Terapon puta, Terapon theraps, Pelates quadrilineatus, Helotes sexlineatus, and Mesopristes cancellatus). Primers were designed to amplify and sequence the 12S rRNA (12S), cytochrome c oxidase subunit I (COI), and cytochrome b (CytB) genes. The concatenated 12S, COI, and CytB sequences (3529 bp) were used to construct the phylogeny of the tigerperches using Maximum Parsimony (MP), Neighbor Joining (NJ), Maximum Likelihood (ML), and Bayesian Inference (BI) analyses. All four analyses supported the monophyly of tigerperches. Except for the MP tree, all phylogenetic trees showed that Terapon jarbua was the first to have diverged from the rest of the tigerperch species examined. The congeneric T. jarbua, T. puta and T. theraps did not group together, suggesting their non-monophyly. However, SH test on the unconstrained (actual observation) and constrained (the three congeneric species were forced to group together) NJ trees showed no significant difference (p = 0.55). -
Current Status of Philippine Mollusk Museum Collections and Research, and Their Implications on Biodiversity Science and Conservation

Such assessments can contribute to a more comprehensive evaluation of natural history museums in the Philippines, as well as biodiversity management. This review showed that local museums in the Philippines have much to improve in terms of their accessibility and geographic coverage in order to effectively cater to research and conservation needs of the country. Online access to databases was lacking for local museums, making it cumbersome to retrieve collection information. The UST museum held the most species and subspecies across all museums (4899), comparable to the national museums of countries such as the USA and France. In terms of size, there were larger Philippine mollusk collections in museums abroad. Majority of mollusk specimens come from Regions 4 and 7, while the CAR and Region 12 were least sampled. Publications on Philippine mollusks are dominated by taxonomic and biodiversity research. -

Length-Weight Relationship and Condition Factor of Silver Therapon, Leiopotherapon Plumbeus (Terapontidae) from Two Brackishwater Habitats 1Dionisia A
Length-weight relationship and condition factor of silver therapon, Leiopotherapon plumbeus (Terapontidae) from two brackishwater habitats 1Dionisia A. Santos, 1Adrian D. C. Manliclic, 1,2Mark N. C. Corpuz 1 Institute of Fisheries and Aquatic Sciences, Center for Research on Aquaculture and Aquatic Resources in Brackishwater Systems, Bataan Peninsula State University, Bayan, Bataan, Philippines; 2 School of Environmental Science and Management, University of the Philippines Los Baños, Los Baños, Philippines. Corresponding author: M. N. C. Corpuz, [email protected] Abstract. This study evaluated the length-weight relationship, (W = aTLb) and condition factor dynamics [K = W/(aTLb)] of endemic silver therapon (Leiopotherapon plumbeus, Kner 1864) based on measurements from specimens collected in two brackish water habitats. Fish specimens were collected from fishponds located in Sampalucan, Orani, Bataan (n=500), and in Almacen river (n=380) in Hermosa, Bataan. Length and weight was affected by sex, sites and seasons. The sexual variation in growth rate as inferred by the length-weight relationship was significant, with females being positively allometric (b=3.11), whilst males were negatively allometric (b=2.88). Spatial variation in growth rate was significant between Sampalucan (b=3.07) and Almacen (b=3.02) despite of both being isometric. The growth coefficient in the wet season displayed isometry (b=3.05), whereas in the dry season, it was negatively allometric (b=2.71). The K values were close to the ideal score of 1. The mean condition factor was significantly influenced by sex (1.023±0.015 for females; 0.949±0.006 for males), sampling sites (0.991±0.005 in Sampalucan; 0.983±0.007 in Almacen), and season (1.017±0.008 in the wet season; 0.974±0.014 in the dry season). -
Aeromonas Veronii and Plesiomonas Shigelloides (Gammaproteobacteria) Isolated from Glossogobius Aureus (Gobiidae) in Lake Sampaloc, Laguna, Philippines
SHORT COMMUNICATION | Philippine Journal of Systematic Biology DOI 10.26757/pjsb2020a14009 Aeromonas veronii and Plesiomonas shigelloides (Gammaproteobacteria) isolated from Glossogobius aureus (Gobiidae) in Lake Sampaloc, Laguna, Philippines Janelle Laura J. Gacad1, * and Jonathan Carlo A. Briones1, 2, 3, Abstract Bacterial infections are high-risk factors in fisheries, with reports of high mortality among diseased fish stocks posing a threat to both capture and aquaculture fisheries in inland waters. Diseases-causing bacteria in fishes may lead to decreased yield and economic loss to fishers, whose livelihood primarily depends on landed catch. Lake fisheries are most affected by such disruptive changes because of limitations in water turnover aggravated by wastewater inputs. In this study, we isolated and characterized gut bacteria from landed catch of the gobiid Glossogobius aureus from Lake Sampaloc, a small but commercially important aquaculture area in Luzon. Isolated axenic gut bacteria were identified through Gram stain reaction, microscopy, API biochemical tests, and 16s rRNA gene sequencing. From these, we identified two species with known fish pathogenicity, namely Aeromonas veronii and Plesiomonas shigelloides which are known to thrive in disrupted and nutrient-rich habitats and cause visible damage to fish health. Interestingly, our samples have shown no such visible signs of the disease. It is therefore important for future researches to determine what conservation and management practices in small inland waters like lakes will limit potential environmental stressors that may trigger susceptibility of both capture and farmed fish species to infection. Ultimately, rehabilitation of inland water aquaculture areas such as Lake Sampaloc is essential not only to fish conservation but also to public health and local food security. -

Pandin Lake Development and Management Plan
PANDIN LAKE DEVELOPMENT AND MANAGEMENT PLAN Volume 1 PANDIN LAKE DEVELOPMENT AND MANAGEMENT PLAN PREFACE This Pandin Lake Development and Management Plan (DMP) is a result of collaborative endeavour among Laguna Lake Development Authority (LLDA), the City Government of San Pablo, and the various stakeholders of Pandin Lake including fishers, landowners, barangay officials, women’s group, youth, non-government organizations, academe, and other government agencies. At present, the Seven Crater Lakes of San Pablo City are swarmed with issues and problems which include but not limited to the following: conflicting interests of stakeholders such as the non-implementation of appropriate zoning plan for fish cages and fishpens; presence of informal settlers along lakes’ shoreline; decreasing lake productivity due to pollution loading; and policy and institutional disputes. In an attempt to address these multi-faceted problems, the LLDA instigated the drafting of a Framework for the Formulation of Development and Management Plan (DMP) for the Seven Crater Lakes. This initiative was undertaken in recognition of the need to mobilize all sectors and stakeholders of the Seven Crater Lakes for a sustained and concerted effort at conserving, protecting and restoring these lakes and the vital resources and amenities that they produce and provide to the people in general. The Framework for the Formulation of Development and Management Plan for the Seven Crater Lakes was approved by the LLDA Board of Directors via Board Resolution No. 464 on 02 April 2014. The main objective of the Framework is to come up with individual Development and Management Plan for each of the Seven Crater Lakes through the involvement of all the concerned stakeholder groups in the process of formulating the DMP based on the perceived problems that they actually confront and experience every day.
