ABSTRACT
This study aims to examine the carotenoid content in Butterfly pea (Clitoria ternatea L.) leaves meal (BPLM) as a source of natural pigment and its effect on the tail color quality of Swordtail fish (Xiphophorus helleri, Heckel. 1848). Completely Randomized Designed (CRD) was applied consisting of four treatments with three replications. The treatments were added 0 % (A), 1 %, (B), 6 % (C) and 12 % (D) of BPLM. The parameters observed included biochemical compound and carotenoid content of dried BPLM, changes in tail color quality, survival rate and water quality. Kruskal-Wallis analysis was applied to analyzed the data of tail color. Data on the survival rate were analyzed using analysis of variance with the F test with 95 % level of confidence. The result showed that there was 9 076 mg kg−1 of carotenoid contained in BPLM. The inclusion of 12 % BPLM to commercial feed was able to enhance the color quality on the tail of the Swordtail fish, i.e average color 5 and a value of color 87.3. Supplementation of BPLM in feed does not significantly affect survival rate and water quality. These result indicated that usage of BPLM is safe as a sources of natural pigment for ornamental fishes, such as Swordtail fish.
