Abstract: The study evaluated the dressing percentage, nutritional quality and mineral composition of six commercial fish species (Scads, Alepes djedaba, Emperors, Lethrinus lentjan, Kingfish, Scomberomorus commerson, Jobfish, Lutjanus...
Olive waste was evaluated as a substitute ingredient for wheat bran in tilapia (Oreochromis niloticus) diets. Five experimental
diets viz., 0 (control), 25, 50, 75 and 100% olive waste (OW) replaced with wheat bran were prepared and randomly...
In the present study the toxic effects of zinc (Zn) on the liver structure of Nile tilapia, Oreochromis
niloticus were investigated. Additionally, we estimated whether Zn concentration and exposure period
influence the degree and nature of...
Freshwater fish Oreochromis niloticus were exposed to sublethal concentrations of zinc for short and
long terms. Responses of hematological parameters which include red blood cells count (RBC) and
hemoglobin content (Hb) were investigated. Serum...
The influence of replacing diet fish meal LT94 (FM) with different levels of full fat soybean meal (FFSB) on growth
performance and enzymes activity in stomach, hepato-pancreas and intestine were investigated for Nile tilapia Oreochromis
niloticus....
Abstract.- Cadmium (Cd) is one of the most harmful heavy metal pollutants in aquatic environments.
Fingerlings of Nile tilapia, Oreochromis niloticus, were exposed to sublethal concentrations (10, 20 and 30% of the
96-h LC50) CdCl2 which caused...
This study was conducted to assess the potential use of maize gluten meal (MG) as a substitute protein source for the
African catfish, Clarias gariepinus. Four experimental diets formulated with different substitution levels of MG (control
0, 25, 50...
Abstract The body composition of Nile tilapia (Oreochromis niloticus) collected from drainage
canals in Al-Ahsa, Saudi Arabia and the concentration of four heavy metals; zinc (Zn), cadmium
(Cd), cobalt (Co) and lead (Pb) in both fish muscles and the...
Abstract Oreochromis niloticus, weighing 36.45± 1.12 g were exposed to 10%, 20% and 30% of
the LC50 of CdCl2 which represents treatments (T1)1.68, (T2)3.36 and (T3)5.03 mg/l, respectively,
for a period of 10, 20 and 30 days. It was found that,...
Abstract Fingerlings of Nile tilapia Oreochromis niloticus were exposed to 1.68, 3.36, and 5.04 mg/L
cadmium (as CdCl 2 ), which represent 10%, 20%, and 30% of their previously determined 96-h LC 50 .
After exposure for 20 days, sections of the...
Abstract This study aimed to evaluate the effects of diet containing the green macroalgae, Ulva lactuca,
on the growth performance, feed utilization and body composition of African catfish Clarias
gariepinus. Four experimental diets were formulated...
Abstract The aimof this study was to evaluate the use of driedmarine seaweed, Gracilaria arcuata for
the first time as dietary ingredient in partial substitution of fishmeal on the growth performance, feed
utilization and body composition of African...
