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) ...
Larval and postlarval development of the window pane shell, Placuna placenta Linnaeus, (Bivalvia: Placunidae) with a discussion on its natural settlement.
(California Malacozoological Society, Inc., 1980)
Stages of development of P. placenta from the straight-hinge veliger to the adult are described. Mature larvae metamorphose at lengths from 220-230 m. Larvae probably attach byssally to the water surface at metamorphosis ...
Ontogeny of foregut in the tropical freshwater crayfish, Cherax quadricarinatus von Martens, 1868 (Parastacidae: Decapoda)
(International Society of Invertebrate Reproduction and Development, 1994)
The comparative morphology of the foregut during development from embryonic larva to adult in Cherux quadricarinatus was examined by light and scanning electron microscopy. Major ontogenetic changes occurred in the gastric ...
Salinity tolerance of larvae of the mangrove red snapper (Lutjanus argentimaculatus) during ontogeny
(Elsevier, 2000)
Salinity tolerance and the effects of salinity on growth, condition factor and chloride cell (CC) densities were evaluated for Lutjanus argentimaculatus larvae during ontogeny. Tolerance of L. argentimaculatus larvae to ...
Size and diel differences in activity patterns of Metapenaeus ensis, Penaeus latisulcatus and P. merguiensis
(Taylor & Francis, 2000)
The nursery function of mangroves as shelter has been postulated to explain the positive correlation between shrimp catches and mangrove area. This study was undertaken to document shelter use and other activities in ...
The effect of thyroxine on the larvae and fry of Sarotherodon niloticus L. (Tilapia nilotica)
(Elsevier, 1983)
Effects of thyroxine (T<sub>4</sub>) (0.1 ppm; 0.3 ppm; 0.5 ppm) on Sarotherodon niloticus L. yolk sac larvae were studied after 4 weeks of treatment from hatching. T<sub>4</sub> at 0.5 ppm accelerated yolk resorption but ...
Ontogeny of feeding apparatus and foregut of mud crab Scylla serrata Forsskål larvae
(Blackwell Publishing, 2007)
The development of the feeding apparatus of the mud crab Scylla serrata larvae was studied using electron microscopy for mandibles and light microscopy for other paired mouthparts and the foregut. The six paired mouthparts, ...
