Tilapia, Oreochromis niloticus (Linnaeus, 1758) and Himri Barbel, Carasobarbus luteus (Heckel, 1843), Duoculture in Net Cages

Effects of triploidy induction on growth and masculinization of red tilapia [Oreochromis mossambicus (Peters, 1852)×Oreochromis niloticus (Linnaeus, 1758)]

Melatonin Induced Changes in Specific Growth Rate, Gonadal Maturity, Lipid and Protein Production in Nile Tilapia Oreochromis niloticus (Linnaeus 1758)

We have investigated the effect of melatonin (MLT) on specific growth rate (SGR% day(-1)), condition factor (k), gonado-somatic-index (GSI), histological structures of gonads, serum as well as gonadal protein and lipid in Nile tilapia Oreochromis niloticus. MLT treatment in the dose of 25 μg/L for three weeks reduced SGR% day(-1) (0.9±0.04) as compared to control (1.23±0.026). The GSI value was...

Biomarkers in Nile Tilapia Oreochromis niloticus niloticus (Linnaeus, 1758) to Assess the Impacts of River Nile Pollution: Bioaccumulation, Biochemical and Tissues Biomarkers

The use of biomarkers has become an important tool for modern environmental assessment as they can help to predict pollutants involved in the monitoring program. Here I present data on bioaccumulation, biochemical and tissues biomarkers in Nile tilapia as early warning indicators of river Nile pollution. Nile tilapia sampled from downstream sites accumulated higher levels of all the detected he...

Survey of some biological characteristics of Golden barb Carasobarbus luteus (Heckel, 1843) in the Shadegan Wetland

Golden barb, Carasobarbus luteus (Heckel, 1843), belongs to the Barbus genus and is one of the freshwater species of Iran and native to Shadegan wetland. Some biological characteristics of Carasobarbus luteus were studied in Shadegan Wetland. Monthly samples were collected from five stations; Doragh (Mahshahr), Rogabe, Khorosy, Salmane and Atish from April 2013 to Mars 2014. 1608 specimens (276...

Tol2-mediated transgenesis in tilapia (Oreochromis niloticus).

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. Here we show that the Tol2 transposon system can be used to create transgenic tilapia with high efficiency. We constructed a line...
