Population structure and genetic diversity of Nile tilapia (Oreochromis niloticus) using microsatellite markers from selected water bodies in southwest Ethiopia.

Background: The Ethiopian southwest drainage has been designated a huge potential for fishery and aquaculture development. However, the genetic diversity of Nile tilapia along the main water bodies has yet to be uncovered. Therefore, this study used microsatellite markers to assess the genetic structure and diversity of Nile cichlid (Oreochromis niloticus) populations.
