Özet

This study was conducted to compare effects of aquria made of glass or fiberglass on growth and pigmentation in goldfish, Carassius auratus (initial weight of 8 1 g) and electric yellow cichlid, Labidochromis caeruleus (initial weight of 0 47 g) for a rearing period of 80 days Skin colour assessment was performed by reflectance spectroscopy with transformation into colour parameters based on tristimulus values, L (lightness), a (redness) and b (yellowness) A lower L and a higher a, b was obtained on skin of goldfish reared in fiberglass aquarium compared to those in glass one (p<0 05) while no differences were observed among L, a and b of electric yellow cichlid reared in glass or fiberglass aquarium (p>0 05) Growth performance, feed conversion ratio and survival ratio in both species were not affected by the aquarium types (p>0 05) Aquarium made of fiberglass should be preferred for goldfish rearing as skin colour is significantly improved in this media
