Gyrodactylids (Gyrodactylidae, Monogenea) infecting Oreochromis niloticus niloticus (L.) and O. mossambicus (Peters) (Cichlidae): A pan-global survey

Acta Parasitologica, 2010
Gyrodactylus infections in intensively-reared populations of Nile tilapia, Oreochromis niloticus niloticus, have been associated world-wide with high mortalities of juvenile fish. In this study, 26 populations of Gyrodactylus parasitising either O.

Vitamin D metabolism in tilapia (Oreochromis mossambicus)

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1998
The present investigation was carried out to study the conversion of [3H]vitamin D3 and 25-OH-D3 in vivo and in vitro in freshwater tilapia (Oreochromis mossambicus). A metabolite co-migrating with 1,25-(OH)2D3 formed from [3H]vitamin D3 in vivo was about 3-fold more concentrated than that of 25-OH-D3.

Cadmium-Inducible Metallothionein in Tilapia ( Oreochromis mossambicus )

Bulletin of Environmental Contamination and Toxicology, 1999
Metallothioneins (MTs), containing over 33% cysteine content and lacking both aromatic amino acids and histidine, are metal binding proteins with low molecular weight (7-14 kDa). The metal ions are bound exclusively through thiolate coordination complexes which involve all 20 cysteine residues (Dunn et al. 1987).

Hepatic toxicological responses of SiO2 nanoparticle on Oreochromis mossambicus

Environmental Toxicology and Pharmacology, 2020
The present study was carried out to investigate the impact of various concentrations of SiO2 nanoparticles (SiO2 NP) on the commonly available freshwater fish Oreochromis mossambicus. The 96 h median lethal concentration (LC50) of SiO2 NP was found to be between 270-280 ppm.

Incorporation and metabolism of cortisol in oocytes of tilapia (Oreochromis mossambicus)

Journal of Experimental Zoology, 2000
The entry and metabolism of 3H-cortisol in oocytes were investigated using isolated follicles of the tilapia (Oreochromis mossambicus) in order to examine the mechanisms of incorporation of maternal hormones into oocytes. The composition of 3H-labeled steroids in the oocyte was analyzed by high-performance liquid chromatography. A significant amount of

Near-infrared orientation of Mozambique tilapia Oreochromis mossambicus

Zoology, 2012
Light plays a pivotal role in animal orientation. Aquatic animals face the problem that penetration of light in water is restricted through high attenuation which limits the use of visual cues. In pure water, blue and green light penetrates considerably deeper than red and infrared spectral components.

Basolateral dipeptide transport by the intestine of the teleost Oreochromis mossambicus

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1996
Transport characteristics of [14C]glycylsarcosine ([14C]Gly-Sar) were measured in herbivorous tilapi (Oreochromis mossambicus) intestinal basolateral membrane vesicles (BLMV) purified with Percoll gradient centrifugation. Specific activity of the vesicle Na(+)-K(+)-adenosinetriphos- phatase was increased 12-fold, whereas specific activity of the brush-

Effect of copper on blood coagulation of Oreochromis mossambicus (Cichlidae)

Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1995
The effect of copper on the blood coagulation in freshwater fish, Oreochromis mossambicus was investigated. These fish were exposed to sublethal copper concentrations over short-term (96 hr) and long-term (4 wk) periods, at 29 +/- 1 degree C (summer) and 19 +/- 1 degree C (winter), in experimental flow-through systems.

Effect of thyroid hormones on hatching in the tilapia, Oreochromis mossambicus

General and Comparative Endocrinology, 1991
Incubation of fertilized eggs of Oreochromis mossambicus in media containing varying doses of T3, T4, and phenylthiocarbamide (PTC) indicated that the thyroid hormones delayed hatching, while the antithyroid drug accelerated it. Denuded eggs were also incubated in the above media and the media were assayed at various time intervals for hatching enzyme.
