Zerdeçal Tozu İlave Edilmiş Diyetlerin Sarı Kuyruk Çiklit Pseudotropheus acei (Regan 1922)'nin Vücut Pigmentasyonu ve Büyüme Performansı Üzerindeki Etkileri

Abstract

There are few studies about the effect of turmeric powder on the skin pigmentation of fish in the literature. This study was conducted to research body and tail pigmentation and growth performance of Pseudotropheus acei (Regan 1922) fed supplemented diets with different ratio turmeric (Curcuma longa) powder. Five diets were prepared by adding four different ratios of turmeric powder (T1: 1%, T3: 3%, T5: 5%, and T7: 7% ) to C: control diet (without turmeric powder). A total of 75 broodstock (mean weight 6g) were randomly stocked (4♀:1♂) in 15 aquariums (70x30x40cm), with three replications. The fish were fed twice daily at 8:30 and 20:30 with the diets supplemented turmeric as ad libitum during the 90 days.At the end of the experiment, the body and tail pigmentation of P. acei significantly increased with increasing turmeric rate in diets (P <0.05). The blue indicator -b values in male and female body color were high in all turmeric supplemented groups compared to the control group (P˂0.05). Also, the yellow color indicator + b value in the color of the male and female tail increased with the addition of turmeric. H ab values were determined in the blue area for the body and in the yellow area for the tail. However, pigmentation of all groups supplemented turmeric powder was visually not different from the color of the control group. There were no significant differences between final weights, weight gain SGR, FCR, and survival rates of P. acei fed diets supplemented with turmeric powder compared to the control (P˃0.05). As a result of the study, skin and tail pigmentation and growth performance of P. acei were not improved by supplementing with turmeric powder to diets.
