Reproductive Aging of African Catfish in Aquaculture [PDF]

open access: yesBIO Web of Conferences, 2021
The work is devoted to the study of reproductive aging of African catfish in the conditions of industrial aquaculture. The problem is urgent, because industrial aquaculture changes the biology of African catfish so much that it loses its ability to ...

MOLECULAR IDENTIFICATION AND PHYLOGENETIC RELATIONSHIP AMONG LOCAL, SANGKURIANG, AND AFRICAN CATFISH BASED ON RAPD MARKER

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2012
Catfish species are commercially cultivated freshwater fish by fish farmer. Formerly, only one species of catfish had been cultivated, namely local catfish (walking catfish) Clarias batrachus.  However, since 1985, local catfish was replaced by a new ...

Eel-tailed Catfish Pituitary Gland: A Sustainable Alternative for Induced Spawning in African Catfish

open access: yesActa Natura et Scientia
The reliance on expensive synthetic hormones and the ethical concerns of sacrificing potential breeders for pituitary gland (PG) extraction in African catfish (Clarias gariepinus) induced spawning necessitate exploring cost-effective and ethical ...

Growth, feed utilization and survival of African catfish,

open access: yesJournal of Aquatic Sciences, 2001
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]

open access: yesJournal of Molecular Endocrinology, 2003
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]

open access: yesJournal 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.

Effects of common carp and African catfish on plankton, periphyton, benthic macroinvertebrates in pond ecosystem

open access: yesAquatic Biology, 2019
As the common carp Cyprinus carpio and African catfish Clarias gariepinus affect biotic assemblages in aquatic ecosystems through their benthivory, their introduction has been considered an environmental concern. We compare the effects of common carp and
