Fig. 3From: Geographical distribution of protozoan and metazoan parasites of farmed Nile tilapia Oreochromis niloticus (L.) (Perciformes: Cichlidae) in Yucatán, MéxicoSpatial clustering of the density (mean abundance) of the ectoparasite species infecting the Nile tilapia Oreochromis niloticus (L.) in Yucatán, Southern México. Red coloured cluster zones indicate higher mean density of the parasite species. The lighter toned cluster zones indicate lower mean density of the parasite species. The parasites are represented by acronyms as follows: a Cs, Cichlidogyrus sclerosus; b Ct, Cichlidogyrus tilapiae; c Cd, Cichlidogyrus dossoui; d Cl, Cichlidogyrus longicornis; e Ci, Cichlidogyrus sp.; f Gy, Gyrodactylus cichlidarum; g Tr, Trichodina sp.; h En, Enterogyrus malmbergi; i Vo, Vorticella sp.; j Cq, Cichlidogyrus quaestio; k Ch, Cichlidogyrus halli Back to article page
