Assessment of temperature effects on body shape in Nile tilapia, Oreochromis niloticus juveniles using the truss network system

Among the environmental factors, water temperature has a significant effect on many aspects of fish life. This study was carried out to examine effects of water temperature on body shape of Nile tilapia, Oreochromis niloticus during the early stages of life using truss network system. A total of 150...
