  1. Substrate type is categorized according to rock (r: small rocks; R: large rocks; sr: solid rock) and sediment (ns: no sediment; s: few sediment; ss: some sediment; sss: much sediment). NT: total number of individuals screened for parasites. NG: number of individuals screened for parasites on the gills. Groups of parasites which are known from Lake Tanganyika fishes [87], but which were not observed in this study, include pentastomids [88, 89], cymothoid parasitic isopods, lernaeid copepods [90], cestodes [89, 91] and leeches [92, 93]. Of these, the isopods and copepods ([90]; Vanhove pers. obs.), pentastomids [94], cestodes ([95]; Vanhove & Pariselle, pers. obs.) were also observed in cichlids, as well as bivalves on the gills (Vanhove & Grégoir, pers. obs.) and the ancyrocephalid monogenean Enterogyrus sp. in the digestive tract (Pariselle, Vanhove, Bamps, Grégoir, Hablützel & Raeymaekers, unpublished data).
