Cortisol-Induced Hepatic Vitellogenin mRNA in Oreochromis aureus (Steindachner)
General and Comparative Endocrinology, 1994Cortisol triggers rapid but transient transcription of the silent vitellogenin (Vg) gene in male Oreochromis aureus, producing short-lived Vg mRNA. Implantation of cocoa butter containing cortisol at 0.8, 8, 20, and 40 micrograms/g fish body wt induced hepatic Vg mRNA within 1 or 2 hr.

A growth trial was conducted to investigate the effect of chromium on growth and carbohydrate utilization of hybrid tilapia, Oreochromis niloticus X Oreochromis aureus. Fish (average initial body weight = 1.3 g) were fed four experimental diets formulated to 45% glucose or dextrin, with or without 2 mg chromium/kg as chromium picolinate (Cr-Pic), for 8

Periodicity of reproductive behaviour by the blue tilapia,Oreochromis aureus
Environmental Biology of Fishes, 1996Oreochromis aureus exhibits a diel periodicity of spawning when maintained on a controlled 14:10 light:dark photoperiod, with a peak in spawning activity during the 11th hour of light. That this periodicity of spawning is a response to light is supported by phase-shifting the light cycle by seven hours.

Abstract An 8-week growth experiment was conducted to estimate the dietary requirement of myo-inositol (MI) for juvenile hybrid tilapia. MI was supplemented at 0, 150, 250, 350, 450, 600, and 1200 mg/kg diet in the basal diet providing 0, 167, 259, 367, 479, 612, and 1253 mg MI/kg diet.

Identification and expression analysis of three c-type lysozymes in Oreochromis aureus
Fish & Shellfish Immunology, 2012Lysozyme is an important molecule of innate immune system for the defense against bacterial infections. Three genes encoding chicken-type (c-type) lysozymes, C1-, C2-, C3-type, were obtained from tilapia Oreochromis aureus by RT-PCR and the RACE method. Catalytic and other conserved structure residues required for functionality were identified.

Molecular cloning and sexually dimorphic expression of DMRT4 gene in Oreochromis aureus
Molecular Biology Reports, 2009The DM-domain gene family has at least eight members with conserved DNA-binding DM-domain, which encodes putative transcription factors related to the sexual regulator Dsx of Drosophila and Mab-3 of C. elegans. Although some of the DM genes are involved in sexual development, the function of most of these genes remains unclear.

Estradiol-induced vitellogenin gene expression in a teleost fish, oreochromis aureus
General and Comparative Endocrinology, 1991Vitellogenesis presents a versatile model for the study of hormone-induced gene expression. We report here the effects of estradiol-17 beta-propionate on vitellogenin gene expression in male Oreochromis aureus, a teleost fish. Vitellogenin mRNA of 6500 nucleotides has been elucidated from the livers of female and estradiol-treated male O. aureus.

Journal of Zoo and Wildlife Medicine, 2007
Tilapia are cultured worldwide and are increasing in popularity among aquaculturalists in the United States; however, data regarding normal health parameters are limited. Few hematologic and plasma biochemical values of clinically normal tilapia have been reported, but these data may be key for identifying and managing disease issues in recirculating ...

Pretreatments of freshwater fish tilapia, Oreochromis niloticus x O. aureus, with 3-methylcholanthrene (3-MC) and polychlorinated biphenyls (PCBs) increased liver microsomal cytochromes P450 (P450) and b5 contents, benzo[a]pyrene hydroxylation, and 7-ethoxyresorufin and 7-ethoxycoumarin O-dealkylations.
