PromethION Sequencing Report:
Output:
48.66 Gigabases
Approximate N50:
5.93 kilobases
Draft Genome Assembly Statistics:
Genome Length:
1.56 Gigabases
BUSCO completeness score (single and duplicated genes):
98.8% [S: 96.9%, D: 2.0%]
Importance:
It serves as an important model species for studying specific stages of limb development within the genus Scelotes, representing an intermediate limb development stage (forelimb digits = 0; hindlimb digits = 2), and for investigating the genomic evolution of vertebrates. It has a restricted distribution and occurs in distinct habitats and regions, making it an excellent model species for biogeographic and molecular ecology studies.

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.
