Growth, feed utilization and survival of African catfish,

Journal 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 ...

Artificial insemination of African catfish (Clarias gariepinus) using cryopreserved sperm

Theriogenology, 2019
In this study, we aimed to develop a practical protocol for using cryopreserved sperm for induced/wild/tank spawning of fish species with external fertilization. Experiments were carried out on African catfish (Clarias gariepinus) as a model species. Sperm was collected for cryopreservation and diluted with the cryomedium (266 mM fructose, 20% methanol)

Resistance of the African (Clarias gariepinus) and the Asian catfish (Clarias batrachus) to channel catfish virus

Aquaculture, 1988
Abstract Resistance of Dutch stocks of African (Clarias gariepinus) and Asian catfish (Clarias batrachus) to channel catfish virus (CCV) was tested. Replicate groups of catfish larvae were challenged by immersion in water containing 105, 104 and 103 TCID50 (50% tissue culture infective dose endpoint)/ml of CCV.

Temperature Preference and Sex Differentiation in African Catfish, Clarias gariepinus

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, 2017
ABSTRACTThe African catfish Clarias gariepinus has a genetic sex determination system in which high temperature induces masculinization. The thermosensitive period for sex differentiation is short and occurs very early (from 6 to 8 days posthatching [dph]). As young juveniles can encounter high masculinizing temperature (36.5°C) in African water points,

Fibrosarcoma in Pond-Cultured African Catfish (Clarias gariepinus)

Tropical Veterinarian, 2013
There is dearth of information in literature about the occurrence and pathology of fibrosarcoma in the African catfish. However, there are a few reports of fibrosarcoma in other fish species and most have been virally associated. Twelve moribund and dead African catfishes with ages ranging from two months to one year were collected from a fish farm ...

Filter-feeding habit of the African catfish

Ethiopian Journal of Biological Sciences, 2013
The feeding habit of the African catfishClarias gariepinus (Burchell) was studied by assessing the stomach contents of 419 fish (287 juveniles - 17.1-44.7 cm TL and 132 adults - 55.2-109.0 cm TL) collected between February 2003 and January 2004 in Lake Chamo.

Phylogeography of the African catfish,Chrysichthys maurus(Valenciennes, 1839)

African Journal of Aquatic Science, 2003
Polymorphism at 19 allozyme loci was studied in 227 individuals of the catfish, Chrysichthys maurus (Valenciennes, 1839), collected from ten populations representing nine different river basins in west Africa. Eleven of the loci studied were polymorphic.

Potentials of poultry offals in African catfish diets

2009
A 70-day feeding trial was conducted to test the effect of partial replacement of fishmeal by poultry offal in African catfish Clarias gariepinus diets. Four isonitrogenous ration containing various levels (0%, control), 30%, 60% and 90% of poultry offal were fed to three replicate groups of C.gariepinus fingerlings with a mean initial weight of 0.74~c

Lip histology of the adult farmed African Catfish (Clarias gariepinus)

Kenya Veterinarian, 2014
The lip histology of the adult farmed African catfish was investigated to fill the knowledge gap in available literature especially those from commercial concrete tanks. This microanatomy is important as the lip is the principal organ involved in prehension.
