Parasite diversity and community structure of translocated Clarias gariepinus (Burchell) in South Africa: Testing co-introduction, parasite spillback and enemy release hypotheses

Seasonal Effects on Health Status and Parasitological Traits of an Invasive Minnow in Iberian Waters

“…In South Africa, the Asian cestode Schyzocotyle acheilognathi co-invaded the region on common carp, goldfish Carassius auratus, and most likely the grass carp Ctenopharyngodon idella (introduced as biological control for invasive aquatic plants). Currently, this intestinal parasite has been found in the African sharptooth catfish Clarias gariepinus, which means that the invasive cestode can complete its entire life-cycle in native species (copepods and fishes) [41]. Such findings demonstrate the elevated adaptiveness of parasites to 'use' novel intermediate and definitive hosts within the introduced ranges.…”

Working towards a conservation plan for fish parasites: Cyprinid parasites from the south African cape fold freshwater ecoregion as a case study

“…To date, there are records for 21 parasite species from ten host species (four endemic and six invasive hosts) in the CF. However, two parasite species are endemic to the CF (reported from the four endemic hosts) and the remaining 19 have the following introduction statuses in South Africa: three parasites are co-invasive, seven are co-introduced with invasive and translocated hosts, one parasite species have an uncertain invasion status, the remaining eight parasite species (one reported from an CF endemic) have yet to be assessed and their origin and host range needs further investigation (see Fryer 1977 ; Van As and Basson 1984 ; Moravec et al, 2016 ; Smit et al, 2017 ; Truter et al, 2023 ). Thus, it is clear that knowledge on diversity of the parasitic communities of native and endemic fishes in the CF is greatly understudied and warrant extensive investigation to determine not only diversity, but also distribution and host specificity.…”

Phylogenetic analysis of coccidia (Apicomplexa: Eimeriorina) in the belica Leucaspius delineatus (Heckel, 1843)

“…The efforts of human economic activities aimed at altering and regulating of natural watercourses, recreational developing of the coastal zone and aquaculture growth have increased significantly over the past 100 years. The side effect of this process has been the expansion outside of natural habitats and introduction of various hydrobiont species Bernery et al, 2022;Zhu et al, 2022;Truter et al, 2023).…”

“…In addition to the obvious consequences of interactions between native fauna and invasive species (competition and predation; genetic influences, hybridization and introgression), there is a threat of introducing associated parasites and other pathogens Truter et al, 2023). Significant epizootics have been described in populations of various fish species caused by viruses, imported with aquacultural species, oomycetes, and protozoa .…”

“…Активность хозяйственной деятельности человека, направленной на изменение и регуляцию естественных водотоков, рекреационное освоение береговой зоны и развитие аквакультуры, существенно возросла за последние 100 лет. Побочным эффектом этого процесса стало распространение за пределы естественных ареалов и интродукция различных видов гидробионтов Bernery et al, 2022;Zhu et al, 2022;Truter et al, 2023).…”
