abstract
The present study was conducted from august 2014 to July 2016 in order to assess fish diversity and its conservation status in Cavally river in an area of intensive mining activities. A total of 76 species were recorded including 8 orders, 20 families and 37 genera. Twenty (20) species were registered for the first time in this river. Characiformes appeared to be the most prolific order in fish population. Among the species sampled, 3 species (Micralestes eburneensis, Chromidotilapia cavalliensis and Coptodon walteri) were endemic to the Cavally River. Fish diversity was higher in upstream area of the zone of intensive mining activities. According to fish conservation status, 52 species were Least Concern (LC), 7 species were Near Threaten (NT), 12 species were Not Evaluated (NE), 4 are Vulnerable and only one species was Data Deficient.
