Ph.D. Student - Biological Sciences (Fish Health and Nutrition)
Research topic: Investigating the potential utilization of insect (Black soldier fly) meal as an alternative protein source in Tilapia feed
Director of Studies: Dr. Daniel Merrifield
2nd Supervisor: Dr. Mark Rawling
Insects are a promising source of protein for fish diets in aquaculture to replace conventional sources such as fish meal due to sustainability issues. This research will investigate the nutrition value of insect meals for omnivorous freshwater fish such as tilapia. In particular, black soldier fly (BSF: Hermetia illucens) meal will be used to replace conventional protein sources in the diets of the fish. The aim is to improve dietary sustainability whilst also promoting good fish health, robustness and growth performance. A series of experiments will be undertaken to elucidate the value of insect meals in this context.
