The commercial value of goldfish (Carassius
auratus) is determined by its attractive colour. Fish cannot
synthesize carotenoids, and hence, natural sources of carotenoids
are supplemented in the diet. In this study, rose
petal meal from four varieties (Jubileums, Brisbane blush,
Double delight and Restless) was added in three concentrations
(2, 4 and 6 gkg-1) to the formulated control feed
and fed to the goldfish, for 45 days. The results revealed
that dietary carotenoids had a significant effect (P \ 0.001)
on growth and pigmentation of goldfish. Increase in length
and pigmentation was proportionate to concentration of
supplements, 6 gkg-1 being most effective. The maximum
increase in weight was observed at 4 gkg-1 concentration
of supplements, with a limiting effect at higher concentrations.
Research on the use of natural sources of carotenoids
to influence growth and colouration is a
significant development for the ornamental fisheries sector,
to enhance quality and market value.
