This study described the fish population in three mining areas. The fish fauna was sampled during eight surveys from November 2017 to January 2019 with two fishing gears (Gill nets and dip nets). A total of 53 species was inventoried in the 3 zones, 38 species in TORTIYA (Diamond area), 28 species in LAUZOUA (Manganese area) and 27 species in HIRE (Gold area). The proportion of constant species is relatively higher at all sites (36 – 62.5%). Invertivores dominated fish communities on all prospected stations. Rarefied richness and Shannon-Weaver index are significantly (kruskal- Wallis test; p <0.05) higher at TORTIYA comparatively to HIRE and LAUZOUA. As for the Pielou’s evenness index, it does not vary significantly (p˃ 0.05) between areas. Similarity analyses (ANOSIM) showed that the composition of the fish assemblage did not change significantly (p˃ 0.05) in the locality of TORTIYA. At the localities of HIRE and LAUZOUA the compositions change significantly (p˂
0.05).Pages: 176-185 | 677 Views 74 DownloadsDownload Full Article:
