Effects of Starvation and Re-Feeding on Growth Performance and Feed Utilization of Rainbow Trout, (Oncorhynchus mykiss)

Abstract

In the present study, the effects of short-term starvation and refeeding on growth and feeding performances of rainbow trout (Oncorhynchus mykiss) with an average initial weight of 100±1 g were investigated. After 1 week adaptation to experimental condition, 80 fish were randomly distributed in 4 fiberglass tanks (3 replication) with a flow-through system. The fish were exposed to 4 different feeding regimes; control: fed two times daily; T1: 1 day starvation and 1 days refeeding; T2: 2 day starvation and 2 days refeeding; T3: 3 days starvation and 3 days refeeding. Short-terms starvation and refeeding was continued for 60 days. At the end of the experiment, final weight, SGR (specific growth rate), WG (weight gain), FCR (feed conversion ratio) and FER (feed efficiency ratio) were determined in control and treated groups. The highest values were observed in control and T1. The lowest values were observed in the T3. The differences between final weight, SGR, WG, FCR and FER were statistically insignificant. In conclusion, rainbow trout have showed a complete compensatory growth depending on times starvation and re-feeding.

Gökkuşağı Alabalıklarının (Oncorhynchus mykiss) Besin Kullanımı ve Gelişim Performansı Üzerine Açlık ve Tekrar Beslemenin Etkileri

Öz

Bu çalışmada, 100±1 g ortalama başlangıç ağırlığına sahip gökkuşağı alabalıklarının besin kullanımı ve gelişim performansı üzerine açlık ve tekrar beslemenin etkileri araştırıldı. Deneme koşullarına adaptasyondan 1 hafta sonra, 80 balık sabit akış sistemine sahip 4 fiberglas tanka rastgele bir şekilde dağıtıldı. Balıklar 4 farklı besleme rejimine maruz bırakıldı; Kontrol: hergün günde 2 kez besleme; T1: bir gün aç bir gün tekrar besleme; T2: iki gün aç iki gün tekrar besleme; T3: üç gün aç üç gün tekrar besleme. Kısa süreli açlık ve tekrar besleme 60 gün sürdü. Deneme sonunda, final ağırlık, SBO (spesifik büyüme oranı), AK (ağırlık kazancı), YDO (Yem değerlendirme oranı) ve YYO (yemden yararlanma oranı) kontrol ve muamele gruplarında belirlendi. En yüksek değerler kontrol ve T1 grubunda gözlemlendi. En düşük değerler ise T3 de gözlemlendi. Final ağırlık, SBO, AK, YDO ve YYO değerleri arasında ki fark istatistiksel olarak önemsizdi. Sonuç olarak, gökkuşağı alabalığı açlık ve tekrar besleme süresine bağlı olarak tam bir telafi büyümesi göstermiştir.
