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. -

Employing Geographical Information Systems in Fisheries Management in the Mekong River: a Case Study of Lao PDR
Employing Geographical Information Systems in Fisheries Management in the Mekong River: a case study of Lao PDR Kaviphone Phouthavongs A thesis submitted in partial fulfilment of the requirement for the Degree of Master of Science School of Geosciences University of Sydney June 2006 ABSTRACT The objective of this research is to employ Geographical Information Systems to fisheries management in the Mekong River Basin. The study uses artisanal fisheries practices in Khong district, Champasack province Lao PDR as a case study. The research focuses on integrating indigenous and scientific knowledge in fisheries management; how local communities use indigenous knowledge to access and manage their fish conservation zones; and the contribution of scientific knowledge to fishery co-management practices at village level. Specific attention is paid to how GIS can aid the integration of these two knowledge systems into a sustainable management system for fisheries resources. Fieldwork was conducted in three villages in the Khong district, Champasack province and Catch per Unit of Effort / hydro-acoustic data collected by the Living Aquatic Resources Research Centre was used to analyse and look at the differences and/or similarities between indigenous and scientific knowledge which can supplement each other and be used for small scale fisheries management. The results show that GIS has the potential not only for data storage and visualisation, but also as a tool to combine scientific and indigenous knowledge in digital maps. Integrating indigenous knowledge into a GIS framework can strengthen indigenous knowledge, from un processed data to information that scientists and decision-makers can easily access and use as a supplement to scientific knowledge in aquatic resource decision-making and planning across different levels. -
Ikan Lokal Tengadak (Barbonymus Scwanenfeldii) Asal Kalimantan Sebagai Andalan Untuk Ikan Budi Daya
Prosiding Seminar Nasional Ikan ke 8 Ikan lokal tengadak (Barbonymus scwanenfeldii) asal Kalimantan sebagai andalan untuk ikan budi daya Irin Iriana Kusmini, Rudhy Gustiano, Mulyasari, Iskandariah, Glenni Hasan Huwoyon Balai Penelitian dan Pengembangan Budi daya Air Tawar Jl. Sempur No. 1 Bogor Surel: [email protected] Abstrak Pengembangbiakan ikan tengadak tidak terlalu sulit dan tidak memerlukan media air bersih, ka- rena ikan ini di habitat asalnya hidup di air yang keruh (sungai). Tujuan penelitian ini adalah mengetahui potensi ikan tengadak asal Kalimantan sebagai kandidat budi daya secara genotip dan fenotip. Metodologi yaitu dengan koleksi dan adaptasi ikan tengadak asal Kalimantan ke media budi daya, identifikasi, karakter genetik dan morfometrik, pembenihan ikan tengadak (embriogenesis dan pertumbuhan benih). Hasil pengamatan menunjukkan ikan tengadak mem- punyai kemampuan adaptasi pada lingkungan yang baru selama lima minggu masa pemeliha- raan dengan sintasan rata-rata 69,28 + 19,64 %. Umur 50-60 hari benih ikan tengadak sudah mencapai ukuran 1-2 cm dengan sintasan 50-60%. Secara kekerabatan baik secara fenotip mau- pun genotip ikan tengadak mempunyai kekerabatan yang lebih dekat dengan ikan tawes albino dibandingkan dengan ikan tawes asal Jawa Barat. Dengan keberhasilan reproduksi ini, maka ikan tengadak mempunyai prospek untuk dikembangkan sebagai ikan budi daya. Kata kunci : tengadak (Barbonymus scwanenfeldii), ikan tawes, potensi, budi daya, kalimantan Pendahuluan Ikan tengadak (Barbonymus schwanenfeldii) merupakan ikan asli Provinsi Kali- mantan. Ikan ini merupakan salah satu jenis ikan lokal yang potensial untuk dikem- bangkan sebagai ikan budi daya (Kristanto et al. 2008 dan Rochman et al. 2008). Do- mestikasi jenis ikan lokal menjadi sangat penting guna keperluan usaha budi daya dan penebaran ikan kembali ke alam. -

The Mekong Region has abundant biodiversity with rich forests, and is second ranked worldwide in terms of diversity of fish species. One special feature is the sustainable lifestyles led by its many people, who utilize the natural environment. The environment of the Mekong basin is not an untouched wilderness, but coexists with human livelihoods. To the socially vulnerable, in particular, the existence of a natural environment in which they can obtain food is critically important. From the start of the 21st century, many development projects have been proposed, purportedly to eliminate poverty. The changes in society and the environment that accompany these development projects, however, can easily lead to environmental destruction and removal of the inhabitants, resulting in the loss of means of livelihood and places for the people to live. Development does not always benefit people financially, but runs the risk of depriving people of independence and forcing them into poverty. -

Rest of the day free. Nestled at the confluence of the Mekong and Nam Khan rivers, in northern Laos, Luang Prabang is considered the heart of Laotian culture. This ancient royal town and UNESCO-World Heritage Site still retains an ethereal ambiance. Much of the town’s allure is the plethora of golden ‘Wats’ – Buddhist temples and pagodas. Two of the most celebrated are 16th century Wat Xieng Thong, which epitomizes the elegance of the regional architecture and Wat Khili, housing priceless Lao Buddhist archives. Day 02: Luang Prabang | Private Blessing Ceremony, '20th UNESCO Anniversary’ Walking Tour and Ethnology Centre Visit Today take part in a private blessing ceremony, administered by Buddhist monks. To commemorate Luang Prabang’s 20th Anniversary as a UNESCO World Heritage Site, ‘A Walk through the Heritage of Luang Prabang’ guidebook was published, highlighting the town’s magnificent historical and heritage aspects. With this inspiring book in hand, embark on a bespoke guided walking tour along narrow streets, discovering distinct Indochina-era and Lao-style architecture. Later, visit the Traditional Art and Ethnology Centre, where exhibits present a rare and fascinating look into Laos’ diverse ethnic minority cultures. Learn more with an informative chat with one of the Centre’s founders. Day 03: Luang Prabang – Pakse – Ban Khiet Ngong | Life Immersed in Protected Wetlands In southern Laos, drive from Pakse, passing through Dong Hua Sao National Park and Bolaven Plateau, arriving at Ban Khiet Ngong Village and Kingfisher Ecolodge. -
