Fish From the Shell: Its Potential in the Quest for Adequate Protein in Ghana

By Prof. Kobina Yankson, UCC Auditorium, March 18, 2004

CHAIRMAN: Rev. Prof. E. A. Obeng (Vice-Chacellor)

Synopsis

Ghana is a protein deficient country with access to less than 40% (Average) of the normal protein requirements for the human body. There is therefore the need to fully exploit all available sources of protein in order to improve on the health of the people which in turn, would impact on productivity. Of the available animal protein in Ghana finfish constitutes nearly 70% with the reminder coming from livestock and poultry. Unfortunately, since the early 1990s finfish production in Ghana, from both capture fishery and aquaculture, has consistently left a huge demand gap of more than 200,000 metric tones annually. Shellfish is one source of animal protein with immense potential in Ghana, but yearning for exploitation. Examples of such shellfish are the West African mangrove oyster (crassostrea tulipa) the West African bloody cockle (Anadara senills), the freshwater oyster (Etheria sp), the freshwater mussel (Aspatheria sp) and the Volta clam (Egeria radiate).

During the past 30 years, the lecturer and his research collaborators have conducted field and laboratory studies on the first three shellfish species named above as well as two foreign species. The thrust of the research has been on the biology and culturing of these edible bivalve mollucs; and this lecture highlights those findings that could be utilized for their mass production. It is emphasized that there is now a body of knowledge and technological know-how available at the department of Zoology, UCC that can be harnessed to establish a pilot oyster farm. The transfer of technology from such a farm to prospective oyster farmers would ensure the production of oysters to bridge our protein requirement gap as well as provide jobs for the coastal people, and oyster shells for the building, mining and poultry industries.

Being among the best graduating students of his class, Professor Yankson was selected to do a year's programme leading to the award of the Bachelor of Science Honours degree, (B.Sc Hons) in 1974. After his national service as a Demonstrator in the Department of Zoology he was appointed full time Demonstrator in 1975. While serving as Demonstrator, he enrolled into the Masters programme of the Department on part-time basis and was awarded the M.Sc. (Zoology) degree in 1977.

He returned to his alma mater to continue his teaching and esearch duties and was subsequently promoted Senior Lecturer in 1987.

In 1988, he returned to the University of Wales, Swansea as a Postal-Doctoral Research Fellow. He also served as a visiting Research Scientist at Cell Systems, Cambridge Science Park, and U.K before returning to Cape Coast in 1989. In 1999, he was a visiting Scientist at the Plymouth Marine Laboratory, U.K.

He was promoted Associate Professor of Zoology in 19994 and attained full professorship status in 2001.

Professor Yankson has taught several courses at both the under-graduate and post-graduate levels. He has supervised several project works and theses of masters and Ph.D. students.

He has researched and published extensively in the areas of Biology and culture of bivalve molluscs (i.e. cockles, oysters and mussels), Brackishwater Ecology and Fisheries, Parasitic Malacology and Macro-Invertebrates of Coastal Waters. His 40 publications include refereed journal articles, a book, conference proceedings and popular articles.

He has attended numerous local and international workshops and conferences at which he presented papers. He enjoys membership of many international Professional Association including the New York Academy of Sciences, Malacological Society of London, Network of Tropical Fisheries Sciences, African Academy of Sciences, West African Sciences Association and the Ghana Science Association.

Professor Yankson has won several professional honours, awards and fellowships some of which are the Darwin Initiative Fellowship; Fellow of the Institute of Biology, Ghana; Commonwealth Academic Staff Fellowship; Cited in "Who is Who" in Science and Technology Education in Africa', and selected ‘Man of the Year 1998' by the American Biographical Institute, etc.

His professional services include being External Examiner and Assessor for all the Public Universities in Ghana and CSIR, Referee for a number of local and International Science journals and Editorial Board Member for a number of Scientific Journals and Magazines including the Everyday Science for Schools Magazine. He was President of the West African Science Association and National President, Ghana Science Association 1993-95.

Professor Yankson has served on a number of national committees/bodies. He served on the National Committee on Marine and Coastal Ecosystems from 1986-87.
