The preservation of the world's biodiversity for future generations has been a global objective for many years, with the establishment of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species in 1964. However, the conservation of parasites is a more recent development and, due to the difficulty in obtaining data and studying some of the parasitic species, comes its own series of challenges. Using parasites of cyprinid hosts (one critically endangered, one endangered and three near threatened) collected from South Africa's Cape Fold freshwater ecoregion (CF) as a case study, this paper discusses the challenges and possible solutions for implementing a fish parasite conservation project. Novel data on the fish parasites (1819 metazoan parasite individuals, representing the Acanthocephala, Cestoda, Copepoda, Digenea, Monogenea and Nematoda) of the CF are provided from the five endemic hosts, Cheilobarbus serra (Peters, 1864), Labeobarbus seeberi (Gilchrist et Thompson, 1913), Pseudobarbus phlegethon (Barnard, 1938), Sedercypris calidus (Barnard, 1938), and Sedercypris erubescens (Skelton, 1974). Conservation statuses for selected parasite taxa are also proposed based on the conservation statuses of the fish hosts, according to the Conservation Assessment Methodology for Animal Parasites (CAMAP).
