FLOODPLAIN RIVER FOOD WEBS IN THE LOWER MEKONG BASIN A Dissertation by CHOULY OU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kirk O. Winemiller Committee Members, Masami Fujiwara Thomas D. Olszewski Daniel L. Roelke Head of Department, Michael Masser December 2013 Major Subject: Wildlife and Fisheries Sciences Copyright 2013 Chouly Ou ABSTRACT The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened by major hydropower development and over-exploitation. Knowledge of river food web ecology is essential for management of the impacts created by anthropogenic activities on plant and animal populations and ecosystems. In the present study, I surveyed four tropical rivers in Cambodia within the Mekong River Basin. I examined the basal production sources supporting fish biomass in the four rivers during the dry and wet seasons and explored the relationship between trophic position and body size of fish at various taxonomic levels, among local species assemblages, and across trophic guilds. I used stable isotopes of carbon and nitrogen to estimate fish trophic levels and the principal primary production sources supporting fishes. My study provides evidence that food web dynamics in tropical rivers undergo significant seasonal shifts and emphasizes that river food webs are altered by dams and flow regulation. Seston and benthic algae were the most important production sources supporting fish biomass during the dry season, and riparian macrophytes appeared to be the most important production source supporting fishes during the wet season. -

Seasonal Hydrology Shifts Production Sources Supporting Fishes in Rivers of the Lower Mekong Basin
1342 ARTICLE Seasonal hydrology shifts production sources supporting fishes in rivers of the Lower Mekong Basin Chouly Ou and Kirk O. Winemiller Abstract: Seasonal hydrology is assumed to be an important reason why the Lower Mekong Basin supports highly productive and biodiverse inland fisheries. We used C and N stable isotope ratios of tissue samples to estimate primary production sources supporting fish biomass in the Mekong and three large tributaries in Cambodia. We used a Bayesian mixing model to estimate relative contributions of four alternative production sources — seston, benthic algae, riparian grasses, and riparian macro- phytes. There was little seasonal variation in isotopic signatures of riparian plants, but benthic algae and seston showed large seasonal shifts in carbon ratios. Seston and benthic algae were the most important production sources supporting fish biomass overall during the dry season, and riparian vegetation was the most important source during the wet season. Sources contributed differentially to biomass of trophic and habitat guilds, especially during the dry season. A dam on the upper Sesan River has changed hydrology, channel geomorphology, and other factors and, compared with the other three rivers, its fish biomass appears to derive from algae to a greater extent. Résumé : L’hydrologie saisonnière est présumée être une importante raison expliquant le fait que le bassin du cours inférieur du fleuve Mékong supporte des pêches continentales très productives et d’une grande biodiversité. Nous avons utilisé les rapports d’isotopes stables du C et du N d’échantillons de tissus pour estimer les sources de production primaire qui supportent la biomasse de poissons dans le Mékong et trois grands affluents au Cambodge. -
Chromosomal Analysis and Nors Polymorphism of Bagarius SUCHUS (Siluriformes: Sisoridae) by Conventional Banding and FISH Techniques
Available online at www.globalilluminators.org GlobalIlluminators FULL PAPER PROCEEDING Multidisciplinary Studies Full Paper Proceeding ETAR-2014, Vol. 1, 46-59 ISBN: 978-969-9948-23-7 ETAR 2014 Chromosomal Analysis and NORs Polymorphism of Bagarius SUCHUS (Siluriformes: Sisoridae) by Conventional Banding and FISH Techniques Nuntiya Maneechot1*, Weerayuth Supiwong2, Alongklod Tanomtong3* 1,2,3KhonKaen University – KhonKaen, Thailand Abstract In the present study, conventional staining and NORs banding as well as Fluorescence in situ hybridization (FISH) using the 18S rDNA and telomeric (TTAGGG)n probes were applied to stain the chromosomes of crocodile catfish, Bagariussuchus (Siluriformes, Sisoridae) from the Chao Praya River, Thailand. Kidney cells of 6 male and 6 female crocodile catfishes were used as a sample. The mitotic chromosome preparations were done directly from kidney cells. The results showed that the diploid chromosome number of B. suchus was 2n=56, the fundamental numbers (NF) were 102 in both male and female. The karyotype comprises 17m+17sm+12a+10t. The nucleolar organizer regions (NORs) were detected by Ag-NORs banding and 18S rDNA probe mapping. The 18S rDNA are terminally located on the short arm adjacent to the telomere of the single pair of the 1st chromosome pair whereas NOR-bearing chromosome is only one chromosome of the 1st chromosome pair (1a 1b, polymorphic characteristic) at the subtelomeric region of the short arm. Moreover, FISH with telomeric probe showed hybridization signals on each telomere of all chromosomes and interstitial telomeric sites were not detected. There were variations in signals of FISH and their position in the karyotype along with variation in DNA sequences. -

Grant Amount: $19,885 Project Dates: November 01, 2012 – October 31, 2013 Implementation Partners for this Project (please explain the level of involvement for each partner): During the project period, lecturers, researchers and students of Royal University of Phnom Penh (RUPP) worked closely with local communities in the 3S region. Local communities were the key partners in the project. They were actively involved in the majority of the project activities including fish species monitoring and recording. More importantly, they assisted us in indentifying the major issues they are facing as well as gaps in their knowledge and awareness about fishery law and regulation. Other key partners were the staff of the Fisheries Department in Seim Pang district and Stung Treng province. Our local researchers of RUPP and district and provincial fishery officials were collaborating in awareness raising and distribution of educational materials about fish species conservation and fishery law to local villagers in the region. They were invited to be speakers in our awareness raising workshop and to our final project workshop. They did not only participate actively in the workshop but also provided feedback and recommendation for future directions of the project. -
