The study of anatomo-pathological lesions carried out on fish cultured and delivered for human consumption is essential. These lesions are an indication of pathologies which can impacted human health status. It is in this light that this study was carried out on 2254 farmed fish specimens collected in the West Region of Cameroon, for better understanding of the diseases affecting fish and improvement of fish production. Macroscopic and histological examination of fish specimens revealed various anatomical pathologies in various parts of the body. Haemorrhagic lesions (19.0%), Erosion (18%), body deformities (1.1%) and color changes (0.6%) were observed, as well as cases of exophthalmia (0.2%). In the same vein, abnormalities of liver and gonad were found (1,3% and 2% respectively). Fish species and sex did not have a significant influence on the prevalence of the pathologies observed (p>0.05). The results showed that the parasite prevalence was insignificantly correlated with the appearance of the observed abnormalities (p>0.05). Morphological and histological alterations could be used as biological markers for degradation of environmental conditions and fish quality. Additional studies should be undergone with the aim of a better understanding of the various causes of fish pathologies and their consequences on fish farming and production.
