Approach to the identification of sex-determining genes in the tilapia genome by genetic mapping and comparative positional cloning
<p>Tilapia (Oreochromis species) are one of the most dominant species in the aquaculture market. Genomic approaches may contribute to tilapia culture in the near future by identifying genes controlling traits valuable at the market. One of the most important traits for farming of tilapia is sex …

Toward genetic marker-assisted improvement of aquaculture stocks
… was used to construct a genomic map for tilapia (Oreochromis sp). A male hybrid between Oreochromis aureus and red O. niloticus was crossed with a female O. mossambicus to produce the 3-way cross mapping family. A panel of DNA samples of 2 grandparents, 2 parents and 60 F2 individuals was screened …

Vitellogenin induction in male Japanese medaka exposed to the chemotherapeutics: oxytetracycline, Romet-30, and copper sulfate
… method. Adult hybrid (Orechromis niloticus x Oreochromis mossambicus x Oreochromis aureus) tilapia were injected with 17â-estradiol (E2) at 5 ìg/g body weight (b.w.) in two separate experiments and exposed to 2.5 ìg/g b.w. E2 through aquaria water in a third experiment. All fish were …

Ecology and conservation of Garra ghorensis, an endangered freshwater fish in Jordan
… a population sympatric with the invasive cichlid Oreochromis aureus. The allopatric and sympatric native populations were present in wadis with minimal habitat disturbance, whereas the sympatric invasive population was present in a wadi with substantial alteration, including some impoundments that …

Characterization of the molecular genetic variation in wild and farmed Nile tilapia Oreochromis niloticus in Ghana for conservation and aquaculture development
The Nile tilapia Oreochromis niloticus is native to Africa and middle East, and is an important source of nutrition for many in sub-Saharan Africa. Understanding the genetic diversity within and differentiation among wild populations can help identify O. niloticus populations that are imperiled and …
