Effects of background colour on growth performance, skin pigmentation, physiological condition and innate immune responses of goldfish, Carassius auratus

---

A study was carried out to investigate the effects of background colour on the growth performance, bskin colour, haematology, physiological condition and non-specific immune responses of goldfish, Carassius auratus. Goldfish were reared in tanks with four different background colours (white, black, blue and red) for 8 weeks. Fish growth performance markedly rose in white background compared with the other treatments. There was no significant difference in haematological parameters or plasma proteins concentrations between treatments. Plasma cortisol of fish reared in red background was significantly higher than that in black and white backgrounds. Plasma antiprotease and lysozyme activities were more than doubled in white and black treatments compared with the red and blue groups. The other immune parameters tested (plasma peroxidase, complement and bactericidal activities) did not significantly change between
treatments. Skin carotenoid content and the intensity of fish skin colour extremely diminished in white background. This study revealed that red and blue backgrounds are chronically stressful and immunosuppressive in goldfish. White
backgrounds will preferably be used for the culture of goldfish for best fish growth. However, a
way to revert the colour loss of goldfish skin reared in white backgrounds remains to be investigated.

Keywords: ornamental fish, tank colour, carotenoids, haematology, stress indicators, nonspecific immunity
