Both recombinant African catfish LH and FSH are able to activate the African catfish FSH receptor [PDF]

Journal of Molecular Endocrinology, 2003
LH and FSH are heterodimeric glycoprotein hormones, composed of a common alpha-subunit non-covalently associated with a hormone-specific beta-subunit. Repeated efforts to isolate catfish FSH (cfFSH) have not been successful and only catfish LH (cfLH) has been purified from catfish pituitaries.

Genome-Wide SNP Analysis of Hybrid Clariid Fish Reflects the Existence of Polygenic Sex-Determination in the Lineage

Frontiers in Genetics, 2022
The African catfish (Clarias gariepinus) may exhibit the co-existence of XX/XY and ZZ/ZW sex-determination systems (SDSs). However, the SDS of African catfish might be influenced by a polygenic sex-determination (PSD) system, comprising multiple ...

Lacustrine radiations in AfricanSynodontiscatfish [PDF]

Journal of Evolutionary Biology, 2009
AbstractSynodontiscatfish are a species‐rich, tropical pan‐African genus that predominately occur in fluviatile environments, but which also form a small radiation within Lake Tanganyika (LT). Here we estimateSynodontisrelationships, based on mitochondrial and nuclear DNA, greatly expanding previous sampling.
