Abstract

In this study, the influence of commercial probiotic, Bacillus spp., supplementation was investigated on growth parameters and digestive protease (alkaline and acid proteases) activities in gilthead sea bream, Sparus aurata, during larval development until on day 40. All experiments were triplicated and designed in administration of probiotic from 3 days after hatching concurrently with starting of exogenous feeding. In the experimental group, probiotic was added to rotifer and tank water until 20 days after hatching. Also, control group did not receive probiotic. In experimental group, the specific activities of alkaline protease was significantly higher (P<0.05) in larvae compared to control group. Acid protease activity was not effected by probiotic supplementation however, it was relatively higher in experimental group than the control (P>0.05). Additionally, S. aurata larvae that had probiotic administered by rotifer with water demonstrated insignificant (P>0.05) increases in both survival (8.5% higher) and specific growth rate (0.7% higher) as compared to controls. As a result, supplementation of probiotic to live food with water could significantly increase the specific activities of alkaline and acid protease and therefore, administration of probiotics by this method would be effective in terms of husbandry parameters and nutritional condition in larvae of S. aurata.

Özet

Bu çalışmada, çipura larva yetiştiriciliğinde 40. güne kadar ticari bir ürün olan probiotik bakteri (Bacillus sp.) eklenmesinin larvalarda büyüme parametreleri ve sindirim enzimleri (alkalin ve asit proteaz) üzerine olan etkileri incelenmiştir. Bütün denemeler 3 tekrarlı yürütülmüş ve probiotik eklenmesi ağız açılımı ile birlikte eş zamanlı olarak yumurtadan çıktıktan sonraki 3. günden itibaren uygulanmıştır. Deneme grubunda, probiotik bakteriler 20. güne kadar rotifer kültürüne ve tank ortamına eklenmiştir. Bunun yanında, kontrol grubuna herhangi bir uygulama yapılmamıştır. Deneme grubunda, alkalin proteaz spesifik aktivitesi kontrol grubuna göre önemli derecede yüksek bulunmuştur (P 0,05). Ek olarak, rotifer kültürüne ve tank ortamına eklenen çipura larvalarının yaşama oranı (%8,5 daha yüksek) ve spesifik büyüme oranı (%0.7 daha yüksek) değerleri kontrol grubuna göre önemsiz farklılıklar göstermiştir (P>0,05). Sonuç olarak, probiotiklerin canlı yem kültürü ve tank ortamına eklenmesi alkalin ve asit proteaz aktivitesini önemli oranda artırmış, bu yüzden probiotiklerin bu yöntemle uygulanmasının büyüme parametreleri ve besinsel durumları açısından daha etkili olduğu sonucuna varılmıştır.
