Fig. 8

Bayesian inference of recent migratory rates for the 13 East African O. niloticus populations. Oval light blue and rectangular light-blue shapes indicate natural and farm populations, respectively. The arrows contain percentage values showing the direction and magnitude of gene flow. Darker and thick arrows represent stronger gene flow, while thin, dotted arrows indicate weaker gene flow. Native and non-native populations are indicated by the letters, “N” and “NN”, respectively. This analysis is based on BayesAss program and for GenAlex program, see the Additional file 1: Table S3
