Gene transfer in tilapia (Oreochromis niloticus)

Aquaculture, 1988
Abstract The microinjection of the human growth hormone gene into the germinal disc and the development of 90-day live transgenic tilapia are reported. Three different spawns, treated 10 min, 21–24 h or 40–43 h after spawning, were used. For microinjection a linear 4.0 kb EcoRI-DNA fragment containing the mouse metallothionein-I promoter (mMT-I ...

Mercury exposure in the freshwater tilapia Oreochromis niloticus

Environmental Pollution, 2010
Mercury (Hg) can be strongly accumulated and biomagnified along aquatic food chain, but the exposure pathway remains little studied. In this study, we quantified the uptake and elimination of both inorganic mercury [as Hg(II)] and methylmercury (as MeHg) in an important farmed freshwater fish, the tilapia Oreochromis niloticus, using (203)Hg ...

Carbohydrate utilization of Oreochromis niloticus

2008
Oreochromis niloticus of mean weight 45.96~c0.06g were fed seven practical diets ranging from 8.77 to 33.77% carbohydrate in 56 days. Mean weight gain were not significantly different (P>0.05) while mean daily gain and specific growth rate varied significantly ...

Lysine requirement of Oreochromis niloticus

2009
Oreochromis niloticus was reared in 54 litre glass tanks being fed with 35% crude protein diets for 56 days. A basal diet consisting intact protein from groundnut cake and guinea com (4.56g lysine/100g protein) ,four graded levels of crystalline lysine was added to formulate diets consisting 6.87, 7.30, 7.41, 7.51 g lysine /100g protein and a reference
