Effect of dietary astaxanthin and background color on pigmentation and growth of
red cherry shrimp (Neocaridina heteropoda) was investigated. A 2x3 factorial in CRD
with two types of diets (with astaxanthin supplementation of 200 mg astaxanthin.kg-1 and
without supplementation) and three types of background colors (white, red and black) was
conducted. After the 8 weeks feeding trial, the results indicated that dietary astaxanthin
and background color had no interaction effect on pigmentation and growth performance
(P>0.05). Astaxanthin-fed groups had significantly greater pigmentation than that of
shrimp fed without astaxanthin (P
