Effects of dietary inclusion Tribulus terrestris and 17 ?-methyltestosterone on sex reversal, growth performance, feed utilization, survival rates red tilapia were evaluated in this study. Red fry with an average weight 0.02 ±0.003 g length 0.6 ±0.012 cm subjected to six different reversal treatments. The experiment lasted for 112 days. Two T. extract treatments (1and 2 g/kg diet); three hormon...

The NEW GIFT Nile tilapia is a national certificated new strain produced through 14 years and 9 generations selection from the base strain of GIFT Nile tilapia. From NEW GIFT Nile tilapia two strain-specific RAPD bands namely S304 and S36 were identified from the amplified bands of 50 and 80 10bp-oligo-nucleotide random primers separately after gel extraction cloning and sequencing of the strai...

Shih-Ling Huang, Wei-Cheng Chen, Mei-Chuan Shei, I-Chiu Liao and Shiu-Nan Chen (1999) Studies on epizootiology and pathogenicity of Staphylococcus epidermidis in Tilapia (Oreochromis spp.) cultured in Taiwan. Zoological Studies 38(2): 178-188. This paper describes the epizootiology of a disease of tilapia with clinical signs that include white nodules and microscopic granulomatous formations. D...

Tilapia is a very common aquaculture species in Taiwan and both the so-called freshwater tilapia (Oreochromis niloticus) and seawater tilapia (O. mossambica) are available. In order to characterize muscle tropomyosin from these tilapia and hybrid ones (O. mossambica × O. niloticus ), the biochemical properties of tropomyosin among these tilapia species were analysed. The nucleotide sequences of...

BACKGROUND The tilapia family of the Cichlidae includes many fish species, which live in freshwater and saltwater environments. Several species, such as O. niloticus, O. aureus, and O. mossambicus, are excellent for aquaculture because these fish are easily reproduced and readily adapt to diverse environments. Historically, tilapia species, including O. mossambicus, S. melanotheron, and O. aure...

Most islet xenotransplantation laboratories have focused on porcine islets, which are both costly and difficult to isolate. Teleost (bony) fish, such as tilapia, possess macroscopically visible distinct islet organs called Brockmann bodies which can be inexpensively harvested. When transplanted into diabetic nude mice, tilapia islets maintain long-term normoglycemia and provide human-like gluco...

Tilapia, a teleost fish species with large anatomically discrete islet organs (Brockmann bodies; BBs) that can be easily harvested without expensive and fickle islet isolation procedures, make an excellent donor species for experimental islet xenotransplantation research. When transplanted into streptozotocin-diabetic nude or severe combined immunodeficient mice, BBs provide long-term normoglyc...

Aquaponics is an innovative, eco-friendly, and sustainable food production system that combines hydroponic crop with recirculating aquaculture. This study aimed to assess the haematological, biochemical, health status of Nile tilapia common carp in monoculture polyculture systems. A total 800 (Oreochromis niloticus) (Cyprinus carpio) average body weight 1.1± 0.2 g were used. The fish divided in...
