This book is a result of concerted research efforts to come up with a meaningful solution in the recovery of the diminishing food resources of the once vibrant fishery of the indigenous fish species of Lake Victoria (Oreochromis variabilis). Both the ecology and aquaculture potential of the candidate species are hereby extensively examined. The results give a promising future towards the domestication of the fish species and its conservation. This work is beneficial to both scholars and many communities who may be interested in farming this tilapia species, a renowned delicacy of the people from Lake Victoria region. Graduate students pursuing environment, ecology and aquaculture options will benefit from a highly scientific way of interpreting and communicating analyzed scientific data. The book serves as a teaching aid to university instructors especially in the field of ecology.
