1 Recep Tayyip Erdoğan Üniversitesi, Su Ürünleri Fakültesi, 53100, Rize, Türkiye DOI : 10.17693/yunusae.v17i27092.286010 Viewed : 3326 - Downloaded : 2412 In this study, the effects on growth, feed conversion ratio, survival rate and economic performance of addition hazelnut meal in different ratio (0%, 15% , 25% and 35% HM) instead of fish meal to diet of angel fish juveniles (average weight 0.5±0.01 g) (Pterophyllum scalare) were investigated. The diets of angel fish juveniles were formulated as isonitrogenous (47%) and isocaloric (2361 kcal kg-1), and the fry were fed 90 days.

The experimental results showed that the best weight gain and specific growth rate were found for control and 15% hazelnut meal diets. These data were reduced after 15% hazelnut meal replacement levels. Feed conversion ratio and protein efficiency ratio were significantly deteriorated after 35% hazelnut meal replacement levels. Condition factor, 15% external to the group (P<0.05) differences were not significant. Survival rate ranged between 93.1 (0% HM I.Grup) and 79.9% (35% HM IV.Grup), and external to two group (P<0.05) differences were not significant.

As a result, with the addition of 15% hazelnut meal in rations of angel fish fry optimum growth was realized and the increase of hazelnut meal in feed have positively affected economic performance. Keywords : Feed formulation,Fish meal,Feeding,Specific growth rate
