Special thanks are due in particular to the Department of Fisheries, which has coordinated project activities in Cambodia, and especially to two members of its staff most directly responsible, Srun Lim Song and Kim Sour. In addition, Harvey Demaine, Siriluck Sirisup, and Eric Meusch of the Asian Institute of Technology’s Aqua Outreach Program were essential partners in supporting early project activities in Cambodia. The fi nancial support of the Swedish International Development Cooperation Agency (Sida) is also gratefully acknowledged. 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
