Özet
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 ug.g(-1) on the initial day in the experimental group. As a result of the measurements performed on the 120(th) day, the pigment values were determined as 30.39 +/- 0.39 mu g.g(-1) in Group A, 39.07 +/- 1.12 mu g.g(-1) in Group B and 35.68 +/- 10.69 mu g.g(-1) in the Group C. Group B pigment source is more effective on the color of tomato clownfish A. frenatus.
