PromethION Sequencing Report:
Output:
13.8 Gigabases
Approximate N50:
5.49 kilobases
Draft Genome Assembly Statistics:
Genome Length:
1.1 Gigabases
BUSCO completeness score (single and duplicated genes):
98.8% [S: 94.9%, D: 3.9%]
Importance:
The Orange river mudfish is a freshwater species endemic to southern Africa. Human activities, such as inter-basin water transfers, have facilitated hybridisation with Moggel (Labeo umbratus). Genomic data are essential to clarify its phylogenetic placement and assess the extent of hybridisation. It is listed as Least Concern on the IUCN Red List. Labeo capensis is an occasional angling species, and it is also used in ecological and physiological research. Additionally, it holds potential as a commercial species in large impoundments.

Labeo rosae
Rednose labeo
Importance:
The Rednose labeo is a freshwater fish endemic to Southern Africa. Preliminary unpublished short DNA sequence data suggest additional taxonomic diversity within this taxon, but comprehensive genomic data are necessary to resolve its phylogenetic relationships and refine its taxonomic diversity. Although the species is currently listed as Least Concern on the IUCN Red List, its population is experiencing a decline due to impacts of human activities. The Rednose labeo is important for subsistence fisheries.
