Euryhaline tilapia Oreochromis mossambicus
regulated by, and suited to, the environment in which they reproduce. In many teleosts, which spawn in either freshwater or seawater, sperm motility is initiated by osmotic shock when sperm are ejaculated. These osmolality dependent regulatory systems are quite different in freshwater cyprinid teleosts, such as carp, gold fish and zebrafish, and marine teleosts, such as the pufferfish and floun...
متن کاملHomologous Recombinant Growth Hormone and Calcium Metabolism in the Tilapia, Oreochromis Mossambicus, Adapted to Fresh Water
Homologous recombinant tilapia growth hormone (rtGH) was tested for its effects on calcium metabolism in freshwater tilapia Oreochromis mossambicus . Fish were fed an optimal ration of 5% of their body mass per day. A positive correlation was found between the amount of food given and the branchial calcium influx. In male tilapia, the mean calcium influxes were 5.80 and 11.71 mmol h21 100 g21 w...
متن کاملSurfactant-induced lipid peroxidation in a tropical euryhaline teleost Oreochromis mossambicus (Tilapia) adapted to fresh water.
Exposure to anionic (sodium dodecyl sulfate, SDS), cationic (cetyl trimethyl ammonium bromide CTAB) and non ionic (Triton X-100) surfactants at a sub lethal concentration of 1 ppm resulted in severe oxidative stress in the hepatic, renal and cardiac tissues of fresh water adapted Oreochromis mossambicus. Hepatic catalase showed significant increase (P<0.001) in all the surfactant exposed fish, ...
متن کاملTgm1-like transglutaminases in tilapia (Oreochromis mossambicus)
Among the adaptations of aquatic species during evolution of terrestrial tetrapods was the development of an epidermis preventing desiccation. In present day mammals, keratinocytes of the epidermis, using a membrane-bound transglutaminase (Tgm1), accomplish this function by synthesizing a scaffold of cross-linked protein to which a lipid envelope is attached. This study characterizes the abilit...
متن کاملBranchial chloride cells in larvae and juveniles of freshwater tilapia Oreochromis mossambicus
Branchial chloride cells in the developing larvae and juveniles of freshwater tilapia, Oreochromis mossambicus, were identified and the membrane Na+/K+-ATPase was localized in situ through binding of the fluorescent dye anthroylouabain. After co-labelling of the cells with the fluorescent probes DASPMI and Con-A-FITC, the mitochondria and apical crypt in the same chloride cells were visualized ...
