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 ...
Genotype by environmental interaction for live weight between two production environments in the GIFT strain (Nile tilapia, Oreochromis niloticus)
Type: Conference Paper
A genotype by environmental interaction study was conducted using the live weight data collected from three discrete spawning seasons of Genetically Improved Farmed Tilapia selective breeding program in Malaysia. Two ...
Genetic improvement programs for red tilapia Oreochromis spp in Asia
Type: Conference Paper
Red tilapia (Oreochromis spp) has become popular in Asian countries due to its greater economic value relative to Nile tilapia. As there is a growing demand for quality seed of this species, the WorldFish Center has initiated ...
