Quality Changes and Microbial Load of Marinated Tilapia (Oreochromis niloticus) Stored at Refrigeration Temperature

Effect of modified atmosphere and vacuum packaging on quality changes of refrigerated tilapia (Oreochromis niloticus) fillets

The assessment effect of modified atmosphere packaging (60% CO2, 10% O2, 30% N2; MAP) and vacuum packaging on the quality of tilapia (Oreochromis niloticus) fillets stored at 4°C was investigated. Maximum inhibition of the bacteria mesophilic and psychrotrophic growth was achieved with stored under MAP. Moreover, tilapia kept under CO2-enriched atmosphere had lower total volatile base (TVB-N), ...

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...

Maintaining Quality and Extending Shelf –Life of Tilapia Oreochromis Niloticus Fish during Storage at 4 ̊C

Keeping food quality among consumers is of high importance. In this study in order to maintain and improve the quality of fish meat, effect of pretreatment with polyphosphates have profound effects on the functional properties of the food products. Experiments were carried out to avoid drip during storage of Tilapia (Oreochromis niloticus)fish under modified atmosphere packaging (MAP).The resul...

Quantitative and molecular genetic studies on temperature-dependent sex determination of Nile tilapia (Oreochromis niloticus)

Aromatase plays a key role during normal and temperature-induced sex differentiation of tilapia Oreochromis niloticus.

In the tilapia Oreochromis niloticus, sex is determined genetically (GSD), by temperature (TSD) or by temperature/genotype interactions. Functional masculinization can be achieved by applying high rearing temperatures during a critical period of sex differentiation. Estrogens play an important role in female differentiation of non-mammalian vertebrates. The involvement of aromatase, was assesse...
