Ethiopia is a country in the horn of Africa endowed with several aquatic resources, including over 20 natural lakes, 12 large river basins, over 75 wetlands, and 15 reservoirs. Micro and macro-dam construction and river impoundment have intensified in recent years and created innumerable large and small water bodies. These water bodies can have great potential for capture and culture fisheries. Yet use of aquatic resources from these water resources is limited only small scale fish capture in some lakes and a few rivers. This book is the first attempt made to present aquaculture potential, cage culture study and national aquaculture development strategy of Ethiopia. It shows the general picture of the aquaculture situation in the country based on scarce data and professional experience. The book will provide a solid basis for further scientific studies for the scientists, aquaculturist, organization working in food security area and the public at large for the benefit of local communities and the country. It will also be a good reference for the investors for investing in fish production in the country.
