Aquaculture, 1996
A growth experiment was conducted to determine the optimal dietary lipid level of juvenile hybrid tilapia, Oreochromis niloticus X Oreochromis aureus. Five isoenergetic and isonitrogenous purified diets containing 0–20% lipid (corn oil/cod liver oil/lard, 1:1:1) in 5% increments were fed for 8 weeks to triplicate groups of tilapia in a recirculated ...

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.

Abstract Streptococcus iniae is a hemolytic, Gram-positive bacterium that causes significant disease problems in freshwater and marine fish species throughout the world. Since first diagnosed in March 1992, S. iniae has become one of the most common bacterial diseases and causes significant economic losses in cultured hybrid tilapia ( Oreochromis

Aquaculture, 2003
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

Variability in reproductive performance of sex-reversed tilapia Oreochromis aureus
Aquaculture, 2008Abstract The reproductive performance of two O. aureus pseudofemale groups was studied in three successive breeding seasons. At the end of the first breeding season, the two initial groups of pseudofemales were divided in two new experimental groups, the first with pseudofemales spawning more than three spawns (HSR = High Spawning Rate ...

Somatic growth characteristics of two tilapia species : Oreochromis aureus and Oreochromis hornorum
2013M.S. University of Hawaii at Manoa 2013. ; Includes bibliographical references. ; Demand for tilapia is growing fast in the United States, positioning tilapia as the second best-selling fish in retail stores behind salmon. In Hawaii, Oreochromis aureus and Oreochromis hornorum tilapias are easily available, but currently, little is known about the ...

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.

Dietary manganese requirements of juvenile tilapia, Oreochromis niloticus × O. aureus
Aquaculture, 2008Abstract To quantify the dietary manganese (Mn) requirements of juvenile tilapia ( Oreochromis niloticus × O. aureus ), manganese sulfate was added to the basal diet at 0, 3, 6, 10, 15, 20, 30 and 60 mg Mn/kg diet providing the actual dietary value of 2.89, 5.86, 8.57, 13.54, 18.51, 23.48, 33.37 and 63.43 mg Mn/kg diet, respectively.
