Personal Profile

Dr (Mrs) Ruby Asmah is Principal Research Scientist with the Fisheries and Aquaculture Division of the Council for Scientific and Industrial Research - Water Research Institute (CSIR-WRI), a Deputy Programme Coordinator for the MPhil Programme in Fisheries and Aquaculture at the CSIR College of Science and Technology (CCST) and a Senior Lecturer in Aquaculture Water Quality Management at the College. She has vast experience in aquaculture development, particularly in relation site selection, water quality management and general farm practices. She is also an expert in environmental monitoring and impact assessments, ecological studies and water resources management. The focus of her research in the recent years has centered on lakes and reservoirs in Ghana, with a view of ensuring sustainable use of these resources in relation to aquaculture development, fisheries, mining and industrial development and climate change. In addition to research and teaching, she is a consultant to international mining companies in Ghana advising them on water quality and ecological issues. She has also undertaken consultancy missions for the United Nations Food and Agriculture Organization. She has supervised a number of students at both masters and doctoral levels at various Ghanaian Universities. She is an external examiner and a reviewer for international peer-reviewed journals. She has obtained research grants from funding agencies including the Royal Society and Leverhulme Trust, DANIDA, the World Bank (through the Fisheries Commission, Ghana). She serves on a number of National and International Technical Committees, including the Natural Resources Technical Review Committee at the Environmental Protection Agency, Ghana, the Aquaculture working group at the Africa Union InterAfrica Bureau for Animal Resources, etc. She has several peer reviewed journal publications, a book, book chapters and conferences papers to her credit.

Research/Special Interests:

Aquaculture systems and operations, appraisal of aquaculture projects and marketing, Geographical Information Systems applications, water resources management, environmental impact assessments

 Current Research:

A proposal on - improving the aquaculture sector in Ghana through improved post-harvest handling of culture fish - is in preparation.
