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.

Species Card Details

Importance:

The Tugela labeo is a freshwater fish species endemic to South Africa. Currently listed as Vulnerable on the IUCN Red List, it is facing population decline due to a variety of recorded threats. It is primarily targeted in occasional recreational angling but also serves as an important species for subsistence fisheries in large dams and riverine habitats.
