Estimating individual feed intake of fish held in groups has long been a challenge precluding precise knowledge of the individual variation of feed efficiency (FE) in fish. In this study, counts of the number of feed pellets (1.63 mg on average) eaten by individual tilapia (Oreochromis niloticus) held in 8 mixed sex groups of 15 fish were measured from video recordings made over a period of 10 days where fish were fed twice daily to achieve compensatory growth after 10 days of fasting.
A major driver of change in the Mekong River basin relates to hydropower development and the consequent changes in landscape and natural resource access regime that it induces. In this paper, we examine how the livelihoods of resettlers evolve following resettlement, and examine the determinants of that process. The study takes place in the context of the Theun Hinboun Expansion Project in Lao PDR.
Sustainable intensification has recently been developed and adopted as a key concept and driver for research and policy in sustainable agriculture. It includes ecological, economic and social dimensions, where food and nutrition security, gender and equity are crucial components. This book describes different aspects of systems research in agriculture in its broadest sense, where the focus is moved from farming systems to livelihoods systems.
