Limit of colour vision in dim light in larvae of the giant freshwater prawn Macrobrachium rosenbergii
(Springer Verlag, 2018)
Colour vision depends on sufficient ambient light and becomes ineffective at a particular low light intensity. It is not known how decapod crustaceans see colour in dim light. In the present study we investigated the 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 ...
Low ph water impairs the tactile sense of the postlarvae of the giant freshwater prawn Macrobrachium rosenbergii
(Penerbit Universiti Sains Malaysia, 2018)
The effect of low pH on the tactile sense of Macrobrachium rosenbergii postlarvae was determined in the laboratory by means of two behavioural assays: shelter (netting) occupancy and jumping response to touch stimuli (taps) ...
Low pH affects survival, growth, size distribution, and carapace quality of the postlarvae and early juveniles of the freshwater prawn Macrobrachium rosenbergii de Man
(Springer Verlag, 2015)
Acidification of rain water caused by air pollutants is now recognized as a serious threat to aquatic ecosystems. We examined the effects of low pH (control pH 7.5, pH 6, pH 5, pH 4) on the survival, growth, and shell ...
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 ...
