ABSTRACT: Goldfish is one of
the ornamental freshwater fish which has interesting body colour. Efforts to
increase the quality of colour needs to be done, by given the material which
can increasing brightness of colour infeed. One of alternative to replace such
materials is the shrimp head meal (SHM). The aim of this research was
determined the relationship between increased colour intensity measured by using the Modified Toca Colour Finder
(M-TCF) and the number of chromatophore cells in the epidermal layer of goldfish
due to the addition of SHM in artificial feed. The research was conducted in
Completed Randomize Design with the additional of SHM (0; 10; 12%) were given
to 30 goldfish/aquaria for 45 days of cultured. The result showed that shrimp
head meal gave significant difference by increasing colour intensity and the
amount of chromatophore cells. Nevertheless the treatment did not give
significant difference on growth. There
was a positive correlation between the numbers of chromatophore cells with the
colour intensity of goldfish. Optimum absorb of carotenoids occured in10% added
of shrimp head meal.
