Optimum low salinity to reduce cannibalism and improve survival of the larvae of freshwater African catfish Clarias gariepinus
(Springer Verlag, 2017)
The freshwater African catfish Clarias gariepinus is carnivorous and cannibalistic even during the larval and juvenile stages and this behavior causes economic losses in aquaculture. This study examined for the first time ...
Colour discrimination in dim light by the larvae of the African catfish Clarias gariepinus
(Springer, 2017)
Many demersal fish species undergo vertical shifts in habitats during ontogeny especially after larval metamorphosis. The visual spectral sensitivity shifts with the habitat, indicating a change in colour vision. Colour ...
Early appearance of the retinal tapetum, cones, and rods in the larvae of the African catfish Clarias gariepinus
(Springer Verlag, 2016)
In the retina of the African catfish Clarias gariepinus, the pigment epithelium and the tapetum were formed in newly hatched larvae, the cones developed within 2 days, and the rods within 3 days after hatching. The retinal ...
Food colour preference of hatchery-reared juveniles of African catfish Clarias gariepinus
(Elsevier, 2017)
Food colour preference is a fundamental aspect of food recognition and has practical application in the formulation of artificial diets and the design of visual baits. Food colour affects growth performance and feed ...
