Species depauperate communities and low abundances of monogenean gill parasites at the edge of the natural distribution range of their cichlid hosts in northern Africa
In Morocco, no work has been carried out on parasitic monogeneans of cichlid fish as far. An examination of the gills of 375 fish from three native species of Cichlidae: Oreochromis aureus, Coptodon zillii and Co...
