Peter starts his PhD in Evolutionary Fish Parasitology

Nestory Peter Gabagambi has started his PhD study in evolutionary fish parasitology. In his study Peter will focus on the interaction between a tapeworm and its fish host in Lake Nyasa/Malawi.

Nestory Peter Gabagambi from Tanzania has started his PhD project at UiB. We know Peter from before as he took his MSc degree at UiB a few years back. His PhD on evolutionary fish parasitology is supervised by Professor Arne Skorping (principal supervisor) and Dr. Mwita Chacha (co-supervisor). Here is the project in Peter's own words:

In this project, I will study the infestation effect of a tapeworm Ligula intestinalis on a biology and ecology in a fish host Engraulicypris sardella in Lake Nyasa/Malawi. The E. sardella fishery is of importance to the economy of Tanzania and a crucial source of protein to the local communities around the coastline of the lake.

However, recently this lake has been invaded by this parasite that could be a potential threat to the fisheries of E. sardella. In this project, I will record the prevalence and distribution of this parasite and I will explore a couple of hypothesises that might help us to understand how we can control this parasite lake wide.
