This study explored possible morphological variations among populations of Barbus altianalis from Uganda with the intent to provide a more cost-effective and reliable platform for elucidating the stocks under combined environmental and anthropogenic influence as a tool for improved fisheries management and conservation. Materials and Methods: Multivariate analysis of morphometric variables was performed to determine the morphological variation and discreteness among three populations of B. altianalis (N = 251) from the lacustrine (Lake Edward) and riverine (River Nile and Kazinga channel) systems in Uganda. Morphological variation was determined using a multivariate analysis of advanced truss and non-truss network systems on all individuals collected from commercial catches. Results: There was a significantly (p<0.001) higher level of heterogeneity among populations. Group means on the DFA1 showed that River Nile (-0.89) separated furthest from Lake Edward (0.79) and the Kazinga channel (0.68). River Nile had the highest number (80.5%) of individuals correctly classified while Lake Edward (67.2%) and Kazinga channel (60.5%) had more misclassifications between them, an indication that they could be much harder to separate. Conclusion: The observed patterns of variation were consistent with the geographical locations of the different water bodies, that the isolating mechanisms are subjecting the different populations to different selection pressure hence different phenotypic responses by the populations.]]>Boulenger, G.A.,190069182187Greenwood, P.H. and K.S.
