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.

Chrysoblephus laticeps
Red Roman
Importance:
The Red Roman, a species endemic to the South African marine environment, plays a significant role in the country's economy through both commercial and recreational fishing. However, overfishing along the South African coastline poses a threat to the species' biodiversity, impacting its ability to adapt to climate change. Sequencing the genome of this species is crucial for informing effective conservation efforts and conducting population genomics research. This marks one of the first reference genomes for an endemic South African marine fish.
