Usage of Lactobacillus rhamnosus as a Probiotic in Sea Bass (Dicentrarchus labrax)

Abstract

Bu çalışmada, levrek balıklarında (Dicentrarchus labrax) probiyotik olarak kullanılan Lactobacillus rhamnosus (ATCC 53103)’un deformasyon oranı, yaşama oranı, ağırlık artışı ve bağırsak mikroflorası üzerine etkisi araştırılmıştır. Bu amaçla, probiyotik etken son konsantrasyonu yetiştirme suyunda 106 kob/ml ve Artemia nauplii kültüründe ise 108 kob/ml olacak şekilde ilave edilmiştir. Bu şekilde probiyotik ilavesi 50. güne kadar devam etmiştir. Bu sürenin sonunda her iki grubun toz yemine 109 kob/g düzeyinde probiyotik ilavesi yapılmıştır. Deneme sonunda larvalardaki deformasyon oranları; yetiştirme suyuna probiyotik ilave edilen grupta %5, Artemia kültürüne ilave edilen grupta %2 ve kontrol grubunda %7 olarak tespit edilmiştir (P<0.01). Deneme gruplarının yaşama oranı kontrol grubuna kıyasla önemli düzeyde yüksek bulunmuştur (P<0.01). Probiyotik ilavesinin balıkların ağırlık artışları üzerinde önemli bir fark oluşturmadığı tespit edilmiştir (P>0.01). Ayrıca, Artemia kültürüne probiyotik ilavesinin Vibrio spp. sayısında önemli düzeyde azalmaya neden olduğu belirlenmiştir (P<0.01).
