Karadeniz'de Ağ Kafeslerde Yetiştirilen Büyük Gökkuşağı Alabalıklarına (Oncorhynchus mykiss) Uygulanan Farklı Besleme Rejimlerinin Büyüme ve Et Kalite Parametreleri ile Ekonomik Dönüşüm Oranları Üzerine Bir Araştırma

Öz

Bu çalışmada, Karadeniz'de ticari olarak üretilen ve başlangıç ağırlıkları 1045.12±43.51 g olan gökkuşağı alabalıklarına (Oncorhynchus mykiss) uygulanan farklı besleme rejimlerinin büyüme, et kalitesi performansları ve ekonomik dönüşüm oranları üzerindeki etkilerinin belirlenmesi amaçlamıştır. Çalışma, Güney Karadeniz'in (Türkiye) Sinop ilçesindeki ticari bir balık çiftliğinde yürütülmüştür. Balıklar üç farklı besleme rejimine göre gruplandırılmış (besleme tablosuna göre beslenen R grubu (% 1 balık ağırlığı); 1 gün beslenen/1 gün aç bırakılan D grubu; 6 gün beslenen/1 gün aç bırakılan E grubu) ve beş ay boyunca günde iki kez beslenmiştir. 150 günlük çalışma sonunda, R ve E grupları en iyi büyüme parametrelerine (ağırlık artışı, spesifik büyüme oranı ve termal büyüme oranı) sahip olduğu ve bu sonuçların istatistiksel olarak D grubundan farklı olduğu bulunmuştur (p<,05). En iyi yem dönüşüm oranlarının (YDO) E (1,57±0,04) ve R (1,59±0,01) gruplarının olduğu belirlenmiştir. Grupların YDO’larına bağlı olarak da E grubunun ekonomik dönüşüm oranının (EDO) diğer gruplardan daha iyi bulunmuştur. Et kalitesi bakımından ise, Karadeniz'de ticari olarak yetiştirilen büyük gökkuşağı alabalığı filetolarının biyokimyasal, yağ asidi ve aminoasit kompozisyonları iyi kalitede, besleyici ve insan tüketimi için güvenli bulunmuştur.

A Research on Growth and Meat Quality Parameters and Economic Conversion Rates of Different Feeding Regimes Applied to Cultured Large Rainbow Trout (Oncorhynchus mykiss) in Net Cages in the Black Sea

Abstract

This study aimed to determine the effects of different feeding regimes applied to large commercial rainbow trout (Oncorhynchus mykiss) with an initial weight of 1045.12±43.51 g in the Black Sea on growth, meat quality performances, and economic conversion rates. The study was conducted in a commercial fish farm in the Sinop district of the Southern Black Sea (Turkey). Fish were grouped according to three different feeding regimes (R group fed according to feeding table (1% fish weight); D group fed 1 day/fasted 1 day; E group fed 6 days/fasted 1 day) and fed twice a day for five months. At the end of the 150-day study, it was found that the R and E groups had the best growth parameters (weight gain, specific growth rate, and thermal growth rate) and these results were statistically different from the D group (p<0.05). The best feed conversion rates (FCR) were determined to be in the E (1.57±0.04) and R (1.59±0.01) groups. Depending on the FCR of the groups, the economic conversion rate (ECR) of the E group was better than the other groups. In terms of meat quality, the biochemical, fatty acid, and amino acid compositions of the large rainbow trout fillets commercially grown in the Black Sea were found to be of good quality, nutritious, and safe for human consumption
