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

ABSTRACT:

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.

Methods

One hundred and sixty-seven fish were collected from Alwero Dam, Baro River, Gilgel Gibe I Dam and Gojeb River southwest of Ethiopia. Genomic DNA was extracted from 40 tissue samples using a Qiagen DNA tissue extraction kit and genetic polymorphism was estimated using GenAlEx6.502 software.

Results

The result showed that four loci were polymorphic and produced 3-6 alleles per locus, while the num
