Description of two new Clarias species from Borneo (Siluriformes, Clariidae)

2003
Clarias pseudoleiacanthus sp. nov. is described from Borneo (Kalimantan, Indonesia). The new species is distinguished from all other Southeast Asian Clarias species by the combination of the following characters: a short distance between the occipital process and the base of the first dorsal fin ray (4.5-5.6% SL), a very short occipital process with a ...

Trematodes (Plathelminthes) of Clarias gariepinus (Pisces: Clariidae) in Lake Tana, Ethiopia

Inland Water Biology, 2017
All of the 166 Clarias gariepinus catfishes in Lake Tana, Ethiopia, were examined for trematode infestation in 2006—2009. Seven trematode species—Eumasenia bangweulensis, Astiotrema reniferum, Orientocreadium batrachoides, Paralecithodendrium chilostomum, Phyllodistomum bavuri, P. tana, and Cladorchiidae gen. sp.—as adult were found. The common catfish

Growth performance of the African catfish Clarias gariepinus (Clariidae) [PDF]

ICLARM Fishbyte, 1990
The growth performance of a number of wild populations of the African catfish C. gariepinus (Clariidae) was assessed by means of the growth index ╪. The values of ╪ ranged from 2.97 to 3.67 with some of the highest values coming from the coldest lakes, suggesting that this catfish can grow well at relatively low temperatures, unlike many other ...

Threatened fishes of the world: Clarias dussumieri dussumieri (Valenciennes, 1840) (Clariidae)

Environmental Biology of Fishes, 2010
Studies are necessary to determine the present distribution and steps to ensure protection of Clarias dussumieri dussumieri (Valenciennes, 1840) (Clariidae) habitats. Also needed are population genetic studies coupled with captive breeding for successful translocation and reintroduction ...

Comparative ovulation in clariidae using crude HCG from early pregnancy urine

Journal of Experimental and Clinical Anatomy, 2009
Members of Clariidae do not spawn in captivity. Culture of these species in captivity must necessitate induced spawning of the eggs. Synthetic hormones have been known to assist this process. This paper used purified crude HCG from early pregnancy urine to assay ovulation in three species of Clariidae.

Assays on the digestive enzymes of sharptooth catfish, Clarias gariepinus (Pisces: Clariidae)

Aquaculture, 1987
Abstract Studies on the digestive enzymes of fish can elucidate some aspects of their nutritional physiology. These data are useful in solving applied nutritional problems, such as the adequacy of artificial food to the digestive abilities of the fish.

Quantitative dietary protein requirements of Clarias isheriensis (Sydenham 1980) (Clariidae) fingerlings

Journal of Applied Ichthyology, 1992
Summary Six isocaloric practical diets containing graded levels of rotein (25, 28, 31, 34, 37, 40%) were formulated and fed to Clarias isheriensis fingerlings (mean weight, 32.47 ± 1.63 g) at 5 % of their body weight twice daily (07.00 and 17.00 h) over 60 days in four replicated treatments using 120-litre fibreglass aquaria. Weight and protein gain

Genomic signatures of terrestrial adaptation in air-breathing catfishes (Clariidae)

AbstractAir-breathing catfishes of the family Clariidae exhibit extraordinary adaptations that enable them to survive outside water for extended periods, yet the genetic and genomic basis of these adaptations remain poorly understood. To study these adaptations, we sequenced and assembled two high-quality genomes of two clariid species,Clarias ...
