In this study, the effect of dietary inclusion of brown fish meal (anchovy, Engraulis encrasicolus L.) and white fish meal (Cod, Gadus morhua L.) on growth performance, feed utilization, protein utilization, nitrogen accumulation and nitrogen loading in juvenile rainbow trout (Oncorhynchus mykiss W.) was investigated. Two experimental isonitrogenic (460 g kg-1) and isolipidic (200 g kg-1) diets were formulated. Each diet was randomly assigned to triplicate groups of 120 juvenile fish with an initial body weight of 10 g. Fish were fed twice daily to satiation for 30 days. At the end of the trial the best spesific growth rate, feed conversion rate, protein efficiency ratio, nitrogen accumulation and nitrogen loading of the group fed white fish meal were obtained and the differences between groups of these parameters were significant (p<0.05)

Kahverengi ve Beyaz Balık Unu İçeren Yemlerin Gökkuşağı Alabalığı, Oncorhynchus mykiss (WALBAUM,1792) Yavrularının Büyümesi Üzerine Etkileri

Öz

Bu çalışmada, alabalık yemlerinde kullanılan kahverengi (hamsi, Engraulis encrasicolus L.) ve beyaz balık ununun (morina, Gadus morhua L.), gökkuşağı alabalığı yavrularının büyüme performansı, yem ve protein değerlendirme, nitrojen birikim ve nitrojen boşaltım miktarı üzerine etkisi araştırılmıştır. Denemede kullanılan yemler isonitrojenik (460 g kg-1) ve isolipidik (200 g kg-1) olacak şekilde formüle edilmiştir. Üç tekerrür olarak planlanan denemede ortalama ağırlığı 10 g olan 120 adet yavru balık kullanılmıştır. Balıklar 30 gün süreyle günde iki kez doyuncaya kadar yemlenmişlerdir. Deneme sonunda en iyi spesifik büyüme oranı, yem değerlendirme sayısı, protein dönüşüm randımanı, nitrojen birikim ve boşaltım miktarıbeyaz balık unu içeren yemle beslenen gruptan elde edilmiş ve gruplar arasındaki fark önemli (p<0,05) bulunmuştur.
