Tol2-mediated transgenesis in tilapia (Oreochromis niloticus) [PDF]

Aquaculture, 2011
The Nile tilapia (Oreochromis niloticus) is an important species in aquaculture and an excellent model system for laboratory studies. Functional genetic analysis using this species has been difficult because existing methods for producing transgenics are inefficient.

The impact of turbidity on foraging and risk taking in the invasive Nile tilapia (Oreochromis niloticus) and a threatened native cichlid (Oreochromis amphimelas)

Behavioral Ecology and Sociobiology, 2020
Anthropogenic activity can increase water turbidity, changing fish behaviour by reducing visibility. The spread of invasive species is also facilitated by human activity, further increasing the pressure on native species.

Cold tolerance of selective breeding of Oreochromis niloticus and oreochromis aureus [PDF]

Egyptian Journal for Aquaculture, 2011
Selected fish for higher growth rate from both O. niloticus and O. aureus were collected and subjected to challenge test for cold. In addition to, fish of both species collected from production ponds of Abbassa were used to compare the cold tolerance of fish. Fry of   similar age were grown under identical conditions. O.

Effect of storage time on the quality of smoked Oreochromis niloticus [PDF]

Heliyon, 2020
Effect of storage time on the quality of smoked Oreochromis nilotius was studied. One hundred fish samples of O. niloticus (average weight 210 ± 15g) was used. Analysis carried out include: proximate, mineral composition (Ca, Na, Fe and Mg), biochemical, amino acid and sensory evaluation.

Performance testing of clonal Oreochromis niloticus lines [PDF]

Aquaculture, 2000
Six different homozygous clonal lines (343 adult fish) were established by gynogenetic reproduction of mitotic gynogenetic Oreochromis niloticus females. Second generation clones (494 adult fish) were obtained by gynogenetic reproduction of clonal females.
