Effect of Carotenoids Vegetable Supplementation in Diet on Color Intensity of Siamese Fighting Fish

Abstract

The aim of this research is to study effect of carotenoid vegetable supplementation from Scallion, Celery and Water convolvulus on color intensity of siamese fighting fish. The carotenoid supplemented diets from scallion, celery, water spinach and dietary fishmeal (control) were provided to Siamese fighting fish at 0.02 g every day. Ten males of Siamese fighting fish were reared in each diet formula and measured by Ultra Scan VIS every month for 3 times. The experiment was conducted at biology laboratory, Faculty of Science and Technology. The results found that the fish feed with diet supplemented with scallion has the highest color intensity compared with the others. The highest values of lightness (L*), redness (a) and yellowness (b) in were 16.58+13.71, 9.50+14.28 and 7.42+5.48, respectively.  Whereas, the value of color intensity was low in the fish received diet supplemented with celery and water spinach that were 42+14.54, 5.53+5.20, 4.68+8.35 and 5.47+5.02, 4.57+5.06, 4.06+7.06, respectively.
