This study analyzes the effect of Nannochloropsis oculata and Porphyridium cruentum as natural pigment sources on skin color of tomato clownfish, Amphiprion frenatus. Two groups, each of 6 fish were fed on feed containing (69.8±9.158 mg.g-1) N. oculata (Group A), and 67.21±7.068 mg.g-1 of P. cruentum (Group B). The third group (Group C) was fed on control basal diet (34.93±29.07 mg.g-1). Total carotenoid content of fish skin was determined at 30-day intervals. At the end of the experiment the highest weight gain was found to be 1.73±0.37g in Group B, whereas the lowest performance (1.29±0.38 g) was received in Group C. The best feed conversion ratio was found in at Group B. The total carotenoid content of skin of fish were found to be 0.77±0.61 µg.g-1 on the initial day in the experimental group.As a result of the measurements performed on the 120th day, the pigment values were determined as 30.39±0.39 µg.g-1 in Group A, 39.07±1.12 µg.g-1 in Group B and 35.68±10.69 µg.g-1 in the Group C. Group B pigment source is more effective on the color of tomato clownfish A. frenatus.
