[ 2 ] - The effects of Marigold as natural carotenoids on scale chromatophores’ variations in blue gourami under different stocking densities
Skin coloration is important in ornamental fish. Fish coloration is due to the presence of chromatophores, which contain pigments and are usually located in dermis. In this study, the effects Marigold as natural carotenoids was investigated on fish scale chromatophores’ variations under different stocking densities. For this, diet containing 2.5% Mari...
