... air-breathing catfishes ( Clarias gariepinus ). These muscles were the mouth closer musculus adductor mandibulae A2A3′, the mouth opener m. protractor hyoidei and the hypaxial muscles responsible for pectoral girdle retraction. Tetanus and twitch activation rise times increased significantly with size...

... for Clarias gariepinus , an air-breathing catfish, are analysed. High-speed X-ray videos were recorded during prey capture of three catfish implanted with small, radio-opaque markers in the cranial elements potentially involved. A kinematic analysis was performed from which data were used as input in planar...

... chambers were closed with a darkened lid to prevent startling of the fish by outside movements. The flow chambers contained about 2 cm of air to allow air-breathing. African catfish Clarias gariepinus Burchell 1822 of 1275±37 g were purchased from a commercial catfish farm (Fleuren Viskwekerij...

...Bendik F. Terjesen; Terry D. Chadwick; Johan A. J. Verreth; Ivar Rønnestad; Patricia A. Wright SUMMARY Embryos and larvae of the African catfish Clarias gariepinus excrete significant quantities of urea. The present study focused on the potential urea-generating pathways during early development...

... transport mechanisms responsible for gastrointestinal Cu uptake are unknown. Everted gut sacs and isolated perfused intestine of Clarias gariepinus were used to explore Cu absorption (at 22 °C). Gut sacs exposed to 100 μmol l −1 mucosal solution Cu ([Cu] m ) showed that Cu was mostly (70 %) absorbed...
