Tilapia is the common name applied to three genera of fish in the family Cichlidae. the genera include Oreochromis, Sarotherodon and Tilapia. Tilapia has become the third most important fish in aquaculture after carp and salmon. The nature’s aim in imparting versatile colours to the fishes is to facilitate their survival and as a mode of communication. Colouration in fishes are highly correlated to their behaviour and habitat as morphological patterns always indicate the physiological functions. Some fishes may change its colour due to environmental conditions. Due to the growth of Tilapia production in aquaculture field, indicates how tilapia is important for world’s total production and economy.
