Abstract (2. Language): 
In this study, determined broodstock diets on egg quality astaksantinin added to the effect of different rates of aquarium fish industry has an important place in the world discus fish (Symphysodon spp). 50 mg.kg-1 (A50)addition astaxanthin at the diameter of the reduced egg production, however, significantly increased the rates of fertilization and the opening of 100 mg.kg-1 (A100) addition astaxanthin decreased egg production, but egg size, fertilization and increase the rate of expansion, 150 mg.kg-1 (A150) addition astaxanthin egg size with the efficiency of egg fertilization rate and the opening rate are found to increase in discus fish broodstock feed (p <0.05).
Abstract (Original Language): 
Bu çalışmada, dünyada akvaryum balığı endüstrisinde önemli bir yeri olan diskus balığının (Symphysodon spp.) anaç yemlerine eklenen farklı oranlardaki astaksantin ilavesinin yumurta kalitesi üzerindeki etkisi araştırılmıştır. Anaç yemine eklenen 50 mg.kg-1 (A50) astaksantinin yumurta verimini ve çapını düşürdüğü ancak, döllenme ve açılım oranlarını önemli derecede artırdığı. 100 mg.kg-1 (A100) astaksantin ilavesinin, yumurta verimini düşürdüğü ancak yumurta çapı, döllenme ve açılım oranını artırdığı, 150 mg.kg-1 (A150) astaksantin ilavesinin ise yumurta verimiyle birlikte yumurta çapı, döllenme oranı ve açılım oranlarını artırdığı tespit edilmiştir (p<0,05)
