“…Exotic fishes were introduced to increase biodiversity and productivity of the lake 100 (Welcomme, 1988). Fish stocking in Lake Kivu dates back in the 1950s where two cichlids, Oreochromis macrochir (Boulenger) and Tilapia rendalli (Boulenger), were introduced due to the renowned ecological plasticity of these species (Chapman et al, 2003;De Vos et al, 2001).…”

An Ecopath model of the southern part of Lake Kivu, a deep African equatorial lake was constructed to quantitatively describe the possible impact of fish introductions in this ecosystem. This study is considered as an initial step in summarizing ecological and biological information, under a coherent framework, on this ecosystem. Fourteen compartments were considered. As a phytoplankton-based food web, it is observed that key food sources are not fully utilized as transfer efficiencies per trophic levels (TL) varies between 4.5 and 9.4%. Zooplankton plays a major role in transferring organic matter from TL1 to higher TLs due to the abundance of zooplanktivores. Shifts in food preferences and distribution of some of the fish functional groups were observed as a response to competition. The majority of fish biomass concentration is in TL3 (55%). The fishery is concentrated at TL3 and can, therefore, be consider as "immature", sensu Odum. The direct and indirect effects of predation between system components (i.e. fish, invertebrates, phytoplankton and detritus) are quantitatively described and the possible influence and role in the ecosystem's functioning of introduced fish species are discussed.

“…In 1945, a few pairs of O. mweruensis from Mweru-Luapula were introduced in the vicinity of Lubumbashi for farming purposes (Thys van den Audenaerde, 1988). Also O. macrochir was introduced in Bangweulu-Mweru (Kipopo) (De Vos et al 2001). Both species hybridize, as discovered by Thys van den Audenaerde (1964), but were classified as subspecies at the time.…”

This study represents the first exploration of the parasite fauna of cichlid fishes in the Mweru-Luapula subregion (Central Africa). Twelve species of cichlids and 14 species of Monogenea from three genera (Cichlidogyrus, Gyrodactylus and Scutogyrus) were collected. We present a first record of the gill parasite fauna of eight host species, Oreochromis mweruensis, Orthochromis sp. 'Mambilima', Sargochromis mellandi, Serranochromis angusticeps, S. stappersi, S. thumbergi and Tylochromis mylodon. The host range of ten parasite species was expanded. The study further includes the description of Cichlidogyrus consobrini sp. n. from S. mellandi and Orthochromis sp. 'Mambilima'. A new morphotype of C. halli is characterized, and three species - C. papernastrema, C. quaestio and C. zambezensis - are redescribed. Furthermore, the biodiversity and host specificity of these parasites is compared with that of cichlid parasites from Lake Kariba and Cameroon. Two species, including C. consobrini sp. n. and a new morphotype of C. halli, are putative endemics. The parasite fauna in Bangweulu-Mweru is highly similar in species composition to Lake Kariba, but in Bangweulu-Mweru the same parasite species are more host-specific, probably because of hydrogeographical differences between the two regions.

“…Astatotilapia burtoni (Günther, 1893; Figure 1), which occurs both within Lake Tanganyika proper and in rivers belonging to the Lake Tanganyika drainage system, is such a generalist haplochromine cichlid (De Vos, Snoeks, & Van Den Audernaerde, 2001;Fernald & Hirata, 1977b;Kullander & Roberts, 2011). Phylogenetically, A. burtoni is nested with the "modern haplochromines" as one of several sister lineages to the Lake Malawi assemblage and the Lake Victoria region superflock (Meyer, Matschiner, & Salzburger, 2015;Salzburger et al, 2005).…”

Astatotilapia burtoni is a member of the “modern haplochromines,” the most species‐rich lineage within the family of cichlid fishes. Although the species has been in use as research model in various fields of research since almost seven decades, including developmental biology, neurobiology, genetics and genomics, and behavioral biology, little is known about its spatial distribution and phylogeography. Here, we examine the population structure and phylogeographic history of A. burtoni throughout its entire distribution range in the Lake Tanganyika basin. In addition, we include several A. burtoni laboratory strains to trace back their origin from wild populations. To this end, we reconstruct phylogenetic relationships based on sequences of the mitochondrial DNA (mtDNA) control region (d‐loop) as well as thousands of genomewide single nucleotide polymorphisms (SNPs) derived from restriction‐associated DNA sequencing. Our analyses reveal high population structure and deep divergence among several lineages, however, with discordant nuclear and mtDNA phylogenetic inferences. Whereas the SNP‐based phylogenetic hypothesis uncovers an unexpectedly deep split in A. burtoni, separating the populations in the southern part of the Lake Tanganyika basin from those in the northern part, analyses of the mtDNA control region suggest deep divergence between populations from the southwestern shoreline and populations from the northern and southeastern shorelines of Lake Tanganyika. This phylogeographic pattern and mitochondrial haplotype sharing between populations from the very North and the very South of Lake Tanganyika can only partly be explained by introgression linked to lake‐level fluctuations leading to past contact zones between otherwise isolated populations and large‐scale migration events.
