ABSTRACT
The present study is aimed to investigate the effect of biofloc intake on Genetically Improved Farmed Tilapia, developed within the system and its influence as feed supplementation on water quality, growth performance, immunological parameters, antioxidant status, immune gene expression, and its resistance to Aeromonas hydrophila infection. Tilapia, considered to be a hardy species, is the second most cultured freshwater fish globally. In 2016, the total production of tilapia was roughly about 6.69 million tonnes and is expected to rise to 7.3 million tonnes by the end of 2030. According to the findings from the previous study, the uptake of biofloc as an additional protein source by freshwater prawn, shrimp, and tilapia indicates that the technology can be applied to both freshwater and seawater culture. The addition of carbon source to maintain the C:N ratio was followed using the method of Avnimelech for the transition of the heterotrophic system.
