Growth, feed utilization and survival of African catfish,
African Catfish, Clarias gariepinus fingerlings (mean weight 3.76 ± 0.13 g) were reared at 9 salinity levels 0.042, 0.3, 0.5, 1.0, 5.0, 10.0, 15.0, 20.0, and 25.0 mgl-1 over a period of 20 weeks. At the end of 20 weeks period the mean weight gain, 15.56 g, (428.7%) of fish reared in 0.042 mg-1 was significantly (P > 0.05) higher than those recorded in ...

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

Lacustrine radiations in AfricanSynodontiscatfish [PDF]
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.
