B   Brief Auto-biography

Benson Ojowi Obwanga has taught at the university level for over 15 years specializing in Zoology of invertebrates and vertebrates of aquatic origin. He has focused his research energies to understand the ecology of aquatic ecosystems, their exploitation by man, interactions and linkages with terrestrial ecosystems and the anthropogenic impacts on these systems vis a vis the climate change conversation. Specifically, has worked to understand the feeding habits of the Nile tilapia (Oreochromis niloticus) in its natural habitat and how this can inform the feeding of this economically important food fish that is widely farmed  not only in Kenya by farmers, but globally. At the moment, he is working on trials using blue green algae (Spirulina plantensis) common in alkaline as a supplement in diets used for production of Oreochromis niloticus. His research outputs have been shared widely to the benefit of the target ecosystem that includes peers, students and farmers. His works have contributed to the conversation on food nutrition and security.  Obwanga who has a diverse network of research partners nationally and internationally has written and won several national and international research grants. He has also implemented several research projects as well as carried out several consultancies in Kenya and beyond. Obwanga is also keen on sustainability of natural resource use and biodiversity conservation.
