A study of the biology of the commonly cultured finfish and shellfish species in tropical Africa is provided.  The course begins with an introductory discussion of the attributes of cultivable species, followed by in-depth study of the morphology, anatomy, respiration, food and feeding habits, growth characteristics, and reproductive habits of selected species.  Local examples of species with potential for culturing will also be considered.  Emphasis will be placed on the relationship between the biological attributes and culture methods.
