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).

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.

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.

Induction of sex reversal in Oreochromis mossambicus by diethylstilbestrol

Journal of Applied Ichthyology, 1990
Summary The efficacy of the synthetic estrogen, diethylstilbestrol (DES), for sex-reversal in the Java tilapia, Oreochromis mossambicus was investigated. Fry of 8–10 mm total length were fed diets containing 25, 50 and 100 ppm of DES for 30 days in plastic pools; this was followed by 45–65 days rearing in fertilized cement cisterns where hormone ...

Feminization of Oreochromis mossambicus by the administration of diethylstilbestrol

Aquaculture, 1989
Abstract Gonadally undifferentiated Oreochromis mossambicus fry were given different doses of diethylstilbestrol (DES) orally for 11 or 15 days and reared for 70 days. All-female populations were produced at doses >100 μg DES/g diet in both treatments. Mortality increased at higher doses (>500 μg/g). The hormone treatment significantly ( P >0.0005)

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-

Basolateral glucose transport by intestine of teleost, Oreochromis mossambicus

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1987
Transport characteristics of D-glucose by isolated basolateral membrane vesicles of the teleost fish, Oreochromis mossambicus, were measured. Specific activity of the vesicle Na-K-adenosinetriphosphatase was increased 11-fold, whereas specific activities of brush-border and organelle membrane enzymes were enriched only 0.3- to 0.8-fold.

Temperature sensitivity of skeletal ontogeny in Oreochromis mossambicus

Journal of Fish Biology, 2004
Sensitivity of skeletal ontogenesis to temperature was assessed in Mozambican tilapia Oreochromis mossambicus and culture temperature manipulations (22, 27 and 32° C) were used to establish if age or length gave the most suitable metric for standardization.
