Genetic quality of cultured tilapia stocks in Africa
Type: Journal Article
African aquaculture is poised for rapid expansion. However, one of the key constraints holding back growth of the sector is the poor quality of the fish stocks available for culture. The problems of declines in growth ...
Influence of fertilizers' types and stocking density on water quality and growth performance on Nile tilapia African catfish in polyculture system
Type: Conference Paper
The effects of fertilizer types and stocking density were investigated on water quality parameters that expected to affect growth performance of the polyculture of Nile tilapia <i> (Oreochromis niloticus) </i>, African ...
Effect of garlic on the survival, growth, resistance and quality of Oreochromis niloticus
Type: Conference Paper
Study was conducted to evaluate the efficiency of the garlic in improving the immune response, survival, growth and disease resistance in Nile tilapia <i>(O. niloticus)</i>. The effects on quality and shelf life of fish ...
Characterization of some bacteria isolated from Oreochromis niloticus and their potential use as probiotics
Type: Journal Article
A total of one thousand Oreochromis niloticus held in earthen ponds of the WorldFish Center were used in this study. Forty of these were randomly collected from the ponds and subjected to bacteriological and pathological ...
Effect of replacing soybean meal by sunflower meal in the diets for Nile tilapia, Oreochromis Niloticus
Type: Conference Paper
This study highlights the potential of using sunflower meal for partial or complete replacement for soybean meal in Nile tilapia diets. Generally, results of the study showed the possibility of replacing of soybean meal ...
Effect of probiotics on the survival, growth and challenge infection in Tilapia nilotica (Oreochromis niloticus)
Type: Journal Article
This study was conducted in order to evaluate the potential benefit of Bacillus pumilus and a commercial product (‘Organic Green’<sup>TM</sup>) as a probiotic in the culture of the tilapia nilotica. Two doses of B. pumilus ...
Performance and survival of three red tilapia strains (Oreochromis spp) in pond environment in Kedah state, Malaysia
Type: Conference Paper
Growth performance (body weight, standard length, body width and depth) and survival of three red tilapia (<i>Oreochromis</i> spp) strains from Malaysia, Taiwan and Thailand were evaluated using 2,867 records collected ...
Total replacement of fishmeal with soybean meal in diets for Nile tilapia in pre-fertilized ponds
Type: Conference Paper
This study was conducted to investigate the effect of replacing fishmeal with soybean meal in diets with different levels of dietary protein on the production economics of Nile tilapia. The results demonstrate that soybean ...
Evaluation of different vaccination strategies for control of (MAS) in Nile tilapia (O. niloticus) in Egypt
Type: Conference Paper
The Motile Aeromonas Septicemia (MAS), caused by Aeromonas hydrophila is among the dangerous diseases encountered in freshwater fish culture. This work aims to compare and evaluate difference vaccination strategies for ...
Estimation of genetic change in the GIFT strain of Nile tilapia (Oreochromis niloticus) by comparing contemporary progeny produced by males born in 1991 or in 2003
Type: Journal Article
Genetic change in the Genetically Improved Farmed Tilapia (GIFT) Nile tilapia (Oreochromis niloticus) was estimated by comparing the performance of the progeny produced from cryopreserved spermatozoa from the base population ...
