Growth performance and post-harvest quality of GIFT Tilapia reared in two different culture systems

The growth performance, feed utilization, sensory evaluation, proximate and fatty acid composition of Genetically Improved Farmed Tilapia (GIFT) reared in different aquaculture systems (tank and cage culture in pond) were examined in a 126-day feeding trial. Throughout the feeding trial, fish were...

Throughout the feeding trial, fish were fed commercial tilapia feed twice a day at 3% of their body weight.
