AcknowledgementCHAPTER | Topic vii Foreword The WorldFish Center is committed to improving the lives of poor people who depend upon living aquatic resources for food and livelihood, a commitment reaffi rmed through our global Fish for All initiative. Making headway in pursuit of this goal requires a strategic focus on regions where the connection between poverty and aquatic resources management is most pronounced, and where opportunities exist to improve diets and raise incomes through better management. The importance of Cambodia’s freshwater fi sheries to the food security and the livelihoods of its rural population is globally exceptional. In many respects, however, the challenges of improving fi shery resources management in Cambodia are representative of

  • 3. the Power Sector 3.1 Laws and Regulations
    Final Report Chapter 3 The Power Sector 3. THE POWER SECTOR 3.1 LAWS AND REGULATIONS The legal and regulatory framework of the power sector of Cambodia is governed by the following laws: Electricity Law Other applicable laws, polices and regulations 3.1.1 Electricity Law The power sector of Cambodia is administered and managed under the Electricity Law which was enacted in February 2001. The Law provides a policy framework for the development of a largely unbundled sector, with substantial private sector participation in generation and distribution on a competitive basis. The Law aims at establishing: 1) the principles for operations in the electric power industry; 2) favourable conditions for investment and commercial operation; 3) the basis for the regulation of service provision; 4) the principles for protection of consumers interests to receive reliable services at reasonable cost; promotion of private ownership of the facilities; and establishment of competition. 5) the principles for granting rights and enforcing obligations; and 6) the Electricity Authority of Cambodia (EAC) for regulating the electricity services. The Law has two key objectives: 1) establishing an independent regulatory body, EAC; and 2) liberalizing generation and distribution functions to private sectors. Two functions of policy making and regulation are clearly separated as shown in Figure 3.1.1. The Ministry of Industry, Mines and Energy (MIME) is responsible for policy making, including drafting laws, declaring policies, formulating plans, deciding on investments, etc. EAC is responsible for regulatory functions, including licensing service providers, approving tariffs, setting and enforcing performance standards, settling disputes, etc. The liberalization and deregulation of the sector has stimulated the private sector with resulting proliferation of independent power producers (IPP) and rural electricity enterprises (REE) in addition to the traditional public utility, the Electricite du Cambodge (EDC).

    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.

The present study was undertaken in order to untangle some of the problems of classification which have beset this group. The genera have not been studied in toto since the days of Bleeker and Gunther. In this study I have made an attempt to clarify the relationships of the various genera, which in some cases has involved revision of generic limits. Lack of time and material has precluded a thorough analysis of the species within any genus; for the same reason no skeletal examinations were possible. It is hoped, however, that a clarification of generic limits through study of external characters will make it easier in the future for interested workers, with sufficient material at hand, to do further and much-needed work on both the genera and the species.

All three species were estimated to have short lifespans (< one year) and breed throughout the year with plural generation alternations within a year. Environment in high temperature accelerated initial growth in all species. In C. aesarnensis, while higher temperature was considered to lead to earlier maturation and downsizing of maturation size, evolutionary downsizing owing to overfishing was of another concern. As the recent economic development and population growth within the country has led to an increase in fish demand and deterioration of the environment, all the species are considered to be in danger of stock decline. Therefore, in the present study, some ideas for stock managements for these species based on biological aspects are discussed. Introduction Lao PDR is a country with rich resources of indigenous fish species, particularly in the basins of the Mekong River and its tributaries. Estimates of the numbers of indigenous fish species in this region range from 700 to more than 1,200 (Kottelat 2001; Sverdrup-Jensen 2002). Among these, various indigenous small-sized fishes are distributed across the country regardless of taxa.

A fundamental goal is to ensure civil society is engaged in biodiversity conservation. www.cepf.net 1 Report on fish catch monitoring - Laos Methodology 8 villages were included in the study in Bokeo from 3 districts (HouayXai, Paoudom and Pakta. Training in how to use the recording form was provided to all target fishermen by a combination of provincial, district and project staff. Data on fish catch was recorded once a week for 10 months, May 2010 to February 2011. 1,811 forms were completed. Key results 57 species of fish were recorded from Houayxai, 35 from Paoudom and 27 from Pakta. There were a total of 79 species from the 3 districts. These are not all river species and indeed not all native, since several villages reported catches from reservoirs, for example of tilapia. Catches were also made in several tributaries as well as the mainstream Mekong, so the results for Laos are not truly comparable with those from Thailand. A total weight of more than 4,600 kg was caught.

  • 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.

Fish were collected with 3 randomized samplings per season at 6 stations using 6 sets of gillnets. A total of 45 fish species were found and most were in the Cyprinidae family. The catch by gillnets was dominated by Parambassis siamensis with an average CPUE for gillnets set at night of 807.77 g/100 m2/night. No differences were detected on CPUE between the seasonal surveys. However, the CPUEs were significantly different (P<0.05) between the stations. The Pak Narmkam station had a higher CPUE compared to the Pak Narmpung station (1,609.25±1,461.26 g/100 m2/night vs. 297.38±343.21 g/100 m2/night). The results of the study showed that the Nong Han Wetlands is a lentic lake and the fish abundance was found to be medium. There were a few small fish species that could adapt to living in the ecosystem. Keywords: fish species, fish composition, abundance, CPUE, Nong Han wetland 1.
