Characterization of oreochromis niloticus strains of fwanyanga fishery of zambia using morphometric methods

Oreochromis niloticus fish was collected from Fwanyanga Fishery in April, 2020. A Dendrogram was used to delineate the sampled specimens using PC-ORDTM Software and the differences among strains were tested using One-way ANOVA in Statistix 9 Software (P = 0.05). Morphometric analysis showed that the sampled fish could be characterized into three different strains. These results showed that the tested fish samples could be grouped into 3 types based on morphometric characters. The morphometric differences among the sampled O. niloticus strains may have appeared due to genetic differences among the collected specimens. The studied fish were all in good condition (K = 1.66 to 1.86).
