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 molybdinus
Leaden labeo

Importance:
The Leaden Labeo is a freshwater fish endemic to Southern Africa. To fully understand its phylogenetic relationships and the evolutionary history and diversification of the Labeo genus in Africa, comprehensive genomic data are crucial. Currently listed as Least Concern on the IUCN Red List, the Leaden Labeo is experiencing population declines due to a range of documented threats. It is occasionally targeted in recreational angling and plays a significant role in subsistence fisheries.
