Abstract

A 45 days feeding trial was conducted to evaluate the effects of dietary fishmeal replacement by super worm (Zophobas morio) meal (SWM) on growth performance, survival, liver, kidney and intestine histology of rainbow trout fingerlings. Fish in triplicate groups (average initial weight 1.39±0.03 g) were fed twice a day ad libitum with 4 isonitrogenous (52% crude protein) experimental feeds in which fish meal were substituted 0, 25%, 50% and 100% with SWM. A separate group of three replicates were fed with a commercial feed. Fish fed with commercial diet and %25 SWM revealed the highest values for growth performance but survival rates were variable. These results indicate that fish meal replacement with SWM up to 25% have no adverse effect on rainbow trout fingerlings and a decrease in growth parameters was obvious with increasing levels of SWM in diets.

Özet

Bu çalışma, balık unu ile süper kurt (Zophobas morio) unu ikamesinin alabalık yavrularında büyüme performansı, yaşama oranı, karaciğer, böbrek ve incebağırsak histolojisi üzerindeki etkilerini izlemek üzere 45 gün süreyle 3 paralelli yürütülmüştür. Ortalama başlangıç ağırlığı 1,39±0,03 gr olan yavru alabalıklar süper kurt unu ile balık ununun %0, %25, %50 %100 oranlarında ikame edildiği dört farklı yem ve bir ticari alabalık yavru yemi ile günde iki kez doyuncaya kadar elle yemlenmiştir. Ticari yem ve %25 süper kurt unu içeren yem ile beslenen gruplarda canlı ağırlık kazancı ve boy artışı bakımından en iyi değerler görülürken, yemdeki süper kurt unu oranı arttıkça büyüme performansı olumsuz etkilenmiştir. Gruplarda gözlenen yaşama oranları değişkenlik gösterse de süper kurt unu kullanılan gruplarda daha düşük gerçekleşmiş ve istatistiki olarak da aradaki fark önemlidir (p<0,05). Elde edilen sonuçlar, süper kurt ununun alabalık yavru yemlerinde balık unu ile büyüme performansını olumsuz etkilemeden %25 düzeyine kadar ikame edilebileceğini ortaya koymuştur.
