451 Khin July Han REPRODUCTIVE BIOLOGY OF FEMALE INDO- PACIFIC KING MACKEREL, SCOMBEROMORUS GUTTATUS (BLOCH& SCHNEIDER, 1801) FROM KYAUKPHYU ENVIRONS, RAKHINE STATE In this study, a total of 240 samples were collected and dissected, from Kyaukphyu Market during the study period from February 2016 to January 2017. Identification was followed after Fisher and Whitehead (1974) and FAO (1984).The gonads were extracted from the specimens. Total body length, standard length, body weight and gonad weight were recorded and preserved in neutral buffer for further histological examination and to analyze the Gonosomatic indices (GSI).The GSI value of female is the highest (4.23± 3.12) in August and the lowest is (1.16 ± 0.06) in June. According to GSI value and based on its histological characteristics, four stages of cyclical changes i.e. maturity in March and July, spawning in April and August, , post spawning in May, September and October, resting in November, December, January, February and June were found in studied species. The breeding season of Spanish mackerel were two peaks in a year such as pre-monsoon and post-monsoon. 2019

455 Khin War War PLANT-PARASITIC NEMATODES ASSOCIATED WITH MONSOON RICE IN BANMAW ENVIRONS A total of 17 species of plant-parasitic nematodes belongs to 15 genera, 11 families and two orders were recorded in soil and root samples at different monsoon rice fields from Banmaw environs. In two orders, the total percent of genera (73.33%) in order Tylenchida was higher than in the order Aphelenchida (26.67%). In soil samples, the highest individual population of plant-parasitic nematodes (2280/100cc soil) was recorded in after harvest sample from rice field III (RF III) and the lowest (7/100cc soil) was in second sample (S II) from rice field I (RF I). All the root samples, the highest (2008/10g root) and lowest (33/10g root) population of plant-parasitic nematodes was recorded in sixth sample (S VI) and fourth sample (S IV) respectively from RF III. Among the recorded plant-parasitic nematodes, three species (Hirschmanniella oryzae, Meloidogyne graminicola, Aphelenchoides besseyi) were the major rice nematodes. In all collected samples, the highest (15246 individuals) and lowest (413 individuals) individual population were observed in H. oryzae and A. besseyi respectively. The highest individual number of major rice nematodes, lowest seed weight and yield were recorded in RF III. The lowest number of nematodes, highest seed weight and yield were observed in RF I. 2019
456 Yadanar Myo SPECIES COMPOSITION, ABUNDANCE AND DIVERSITY OF AVIAN FAUNA IN PAKOKKU ENVIRONS, MAGWAY REGION Avifauna was investigated in four study sites of the Pakokku environs during July 2015 to June 2016. A total of 126 bird species belonging to 81 genera, 41 families and 16 orders were recorded. Of these, 35 species were water birds and 91 species were terrestrial birds. The bird species were represented with 25 migrants and 101 residents. During the study period, two endemic species, namely Turdoides gularis (White-throated Babbler) and Mirafra microptera (Burmese Bushlark) were recorded. The highest species composition was found in order Passeriformes (51.59%, 65 species), followed by Pelecaniiformes (8.73%, 11 species). Relative abundance indicated six species as very common, 10 species as common and 110 species as uncommon in Pakokku environs. In the study area, the highest species richness and diversity values were evaluated in Site I (d =11.643, D= 0.077, H'= 3.199) and Site III (d= 10.934, D= 0.039, H'= 3.646). This situation may be related to the habitat conditions and availability of food sources. Pakokku environs may be considered rich in bird diversity due to occurrence of high number of bird species and individuals. 2019
457 Myo Sandar Win POPULATION, BREEDING STATUS, AND HABITATS UTILIZATION OF SARUS CRANE GRUS ANTIGONE IN AYEYARWADY REGION The present research deals with the estimate population, breeding status, and habitats of the globally threatened vulnerable species of Sarus Crane Grus antigone in Ayeyarwady Region. Data recorded by two methods of point transect and direct observation method in breeding season (June–October) and non-breeding season (November-May). Estimate population status survey was carried out toward end of the breeding season. This is the time when new chicks have fledged and recruitment rate can be estimated. At each Crane site, habitats were collected by rapid assessment by level 4 of Asian Wetland Inventory Handbook (Finlagson et al, 2002). According to the data, 299 individuals of Sarus Crane and 78 nests were recorded from June 2017 to May 2018. 2019
458 Myint Naung SPECIES COMPOSITION OF AVIFAUNA IN NORTHERN PART OF ALAUNGDAW KATHAPA NATIONAL PARK, SAGAING REGION The study was conducted on the occurrence of bird species in northern part of Alaungdaw Kathapa National Park during the study period from September 2012 to August 2015 with the objectives to identify the avifauna and to examine the species composition and relative abundance of bird species. Sampling sites were stratified based on the vegetation type and fixed radius point count technique was employed. A total of 109 species belonging to 76 genera, 38 families under 13 orders were recorded. The maximum percentage of family composition was observed in Picidae. Black-crested bulbul Pycnonotus flaviventris was found as very common species although Great Hornbill Buceros bicornis, Oriental-scops Owl Otus sunia and Daurian Redstart Phoenicurus auroreus were recorded as uncommon species. The species composition of bird in dry season was significantly different with other seasons. Globally threatened species such as Great Hornbill Buceros bicornis and Red-breasted Parakeet Psittacula alexandri as Near-threatened species, and Great Slaty Woodpecker Mulleripicus pulverulentus as vulnerable according to IUCN Redlist (2015) were recorded. This result is hoped to provide some data to attract more ecotourism in future. 2019
459 Htay Khaing SPECIES COMPOSITION AND THE EFFECTS OF WATER LEVEL FLUCTUATION ON WATERBIRD POPULATION AT INMAGYI WETLAND IN MYINMU TOWNSHIP, SAGAING REGION The species composition and the effects of water level fluctuation on waterbird population was determined by using fixed radius point count method at Inmagyi Wetland in Myinmu Township, Sagaing Region. A total of 31 waterbird species belonging to 27 genera, 12 families and seven orders were recorded in study areas. The study was conducted from July 2016 to June 2017. Out of 31 species, 19 species were residents and 12 species were winter visitors. Three globally Near Threatened species, Spot-billed Pelican Pelecanus philippensis, Painted Stork Mycteria leucocephala and Black-headed Ibis Threskiornis melanocephalus were observed during the study period. The study area was divided into two habitats, that is, marshy swamp and open water body to study the effects of water level fluctuation on waterbird population. The result of the Pearson’s test indicated that negative correlation (r = -0.171) was observed between water level and waterbird population in marshy swamp habitats and almost no correlation (r = 0.005) was observed in open water body habitat. However the population of waterbirds in marshy swamp were significantly different from open water body. This study revealed that Inmagyi Wetland has habitat heterogeneity and seasonal fluctuation of water level that had attracted residents and winter visitors of waterbird species to perform various activities such as feeding, roosting and breeding. 2019
460 Aung Zaw Myint MINERALOGICAL AND GEOCHEMICAL CONSTRAINTS ON THE GENESIS OF GRANITE-RELATED W-SN-MO MINERALIZATION IN PADATGYAUNG-MYINMAHTI AREA, EAST OF NAY PYI TAW, CENTRAL MYANMAR* Padatgyaung-Myinmahti area is located 80km E from Nay Pyi Taw and lies at the eastern margin of the Shan Plateau. W -Sn-Mo mineralization is spatially associated with the biotite granite of Early Eocene age and low-grade metasediments of Carboniferous to Early Permian Mergui Group. The biotite granite is slightly weathered and intensively greisenized in some places. Quartz veins generally trendN-S and NE-SWwith steep dipping (80°-90°). Cassiterite is common in greisenized zone whereas wolframite and molybdenite is prevalent in quartz vein. Greisen is mainly composed of quartz and muscovite with rare fluorite. The quartz veins contain wolframite and molybdenite associated with the minor amount of galena, pyrite, chalcopyrite, sphalerite, arsenopyrite, bismuthinite, cassiterite, scheelite, bornite and covellite. Wolframite composition ranges from hubneritic to ferberitic composition. Geochemical data indicates that the granites are peraluminous and highly fractionated, and characterized by high SiO2and high A/CNK [molecular Al2O3/ (CaO+Na2O+K2O)] values(>1.1). The granite has tectonic affinities with WPG (within-plate granite) or post-orogenic setting. Trace element geochemistry, distinct negative anomalies of primitive-mantle normalized Ba, Sr, Ti, Nb and the positive Pb, Rb, Y anomalies reveal that distinct crustal sources have been involved in the formation of granite and associated W-Sn-Mo mineralization. 2019
