Stress in African catfish (Clarias gariepinus) following overland transportation

Fish Physiology and Biochemistry, 2013
Of the many stressors in aquaculture, transportation of fish has remained poorly studied. The objective of this study was therefore to assess the effects of a (simulated) commercial transportation on stress physiology of market-size African catfish (Clarias gariepinus). Catfish weighing approximately 1.25 kg were returned to the farm after 3 h of truck-

North African Catfish Clarias gariepinus (Burchell)

2017
Fast expansion of aquaculture in China largely relies on the introduction and use of non-native species. However, the introduction and use of non-native species may have negative impacts on local ecosystems and societies. Clarias gariepinus has been widely farmed in China after introduced in 1980 from Africa.

In vitro adenine nucleotide catabolism in African catfish spermatozoa

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2004
It has been shown recently that African catfish (Clarias gariepinus) spermatozoa possess relatively low ATP content and low adenylate energy charge (AEC). One of the possible explanations for this phenomenon is that the spermatozoa actively catabolize adenine nucleotides.

Male-specific DNA markers from African catfish (Clarias gariepinus)

Genetica, 2000
We searched for sex-specific DNA sequences in the male and female genomes of African catfish, Clarias gariepinus (Burchell, 1822) by comparative random amplified polymorphic DNA (RAPD) assays performed on pooled DNA samples. Two sex-linked RAPD markers were identified from the male DNA pool and confirmed on individual samples, showing good agreement ...

Two gonadotropin-releasing hormones from African catfish (Clarias gariepinus)

Biochemical and Biophysical Research Communications, 1992
Two forms of gonadotropin-releasing hormone (GnRH) have been purified from brain extracts of the African catfish, Clarias gariepinus, using reverse-phase high performance liquid chromatography (HPLC) and radioimmunoassay (RIA). The amino acid sequences of both forms of African catfish GnRH were determined using Edman degradation after digestion with ...

Semen collection in catfish species, with particular emphasis on the African catfish.

CABI Reviews, 2003
Abstract This minireview describes the current knowledge on semen collection in captive male catfish. It is well known that when some catfish species, such as the African catfish ( Clarias gariepinus and Heterobranchus longifilis ), channel catfish ( Ictalurus punctatus
