Dr. Mirera Oersted David is a Senior Research Officer working for Kenya Marine and Fisheries Research Institute (KMFRI) and currently the Assistant Director in charge of Mariculture Research and Development. Dr. Mirera has significant experience in mariculture development in Kenya and the Western Indian Ocean (WIO) Region. He was in the taskforce that developed the 1st aquaculture policy for Kenya and is the brainchild of community mariculture development in Kenya through milkfish and mud crab farming. Has been engaged in several mariculture development interventions including providing an expert assessment of the suitability of mud crab farming in Seychelles, Potential of mariculture development in Kenya and Evaluation of the level of implementation of mariculture and fisheries interventions and collaboration between the United Republic of Tanzania and FAO. Dr. Mirera has made several innovations in mariculture that include development of drive-in cages for mud crab cages, fabrication of innovated plastic cages for mud crab fattening, design and development of simple marine earthen ponds that are regulated by the tides and introduction of freshwater Nile tilapia into marine waters. He is a mentor and supervisor of several MSc. Students from different Universities and is an external examiner to three universities in Kenya. He has successfully implemented a number of research and development projects in aquaculture with different partners. Dr. Mirera is the leader for aquaculture under the Earth System Governance Task Force on Ocean Governance, Kenyan representative to the African Research Network for Marine Aquaculture (AFriMAQUA) project, and undertakes review for different peer reviewed journals and projects.
