Fig. 2.
The 214 length-weight relationships of O. niloticus were plotted in log (a’) vs b. Fourteen outliers were marked in the graph with blank circles and were eliminated in subsequent analyses. Regression line: log(a’) = 1.16-0.95b, n = 200, R2 = 0.702, p < 0.05.

Frequency distribution of index b based on 200 records for O. niloticus, 5th percentile= 2.07 and 95th percentile = 3.21. Gaussian distribution line was superimposed.
Fig. 1.
The distribution was available on the FishBase website (Froese and Pauly, 2023), and Oreochromis niloticus (Linnaeus, 1758) was found in 92 countries. In the figure, the light gray sections were the native areas and the black sections were the invasive areas. In the 36 countries with the Length-weight relationships (LWRs) of O. niloticus data, the solid circles represented the native populations and the triangles indicated the invasive populations.
