The Effect of Saponin on Enzyme Activities, Hepatosomatic Index and Growth Rate of Rainbow Trout

Öz

Saponin is the active matter of Verbascum plant which used in fisheries in East Anatolia of Turkey, utilizing with the anesthetic specifications of plants. In this study the effects of saponin on the enzyme activities (GR and G6PD), hepatic-somatic index and growth rate of rainbow trout were researched. Fish were fed with the two doses of saponin (150 mg kg-1 and 300 mg kg-1) added feeds for 45 days. At the result of the experiment; decrease obtained in all parameters, GR and G6PD enzyme activities, HSI and live weight gaining of rainbow trout according to the doses.

Saponinin Gökkuşağı Alabalığında Canlı Ağırlık Artışı, Hepatosomatik İndeks ve Bazı Antioksidan Enzim Aktiviteleri Üzerine Etkileri

Öz

Bu çalışmada, Doğu Anadolu Bölgesi\'nde, anestezik etkisinden yararlanılarak yerli alabalıkların avlanmasında kullanılan sığır kuyruğu (Verbascum spp.) bitkisinin etkili maddesi olan saponinin iki farklı dozunun (150 mg kg-1 ve 300 mg kg-1) ilave edildiği yemlerle 45 gün beslenen gökkuşağı alabalıkları (Oncorhynchus mykiss)\'nda bazı enzim (GR ve G6PD) aktiviteleri, HSİ (hepatosomatik indeks) ve canlı ağırlık artışı üzerine etkileri incelenmiştir. Çalışma sonunda GR ve G6PD enzim aktiviteleri S150 ve S300 gruplarında kontrol grubuna oranla düşüş göstermiş, GR\'deki düşüş istatistiki olarak önemli bulunurken, G6PD\'deki düşüş önemli bulunmamıştır. HSİ ve canlı ağırlık artışı parametrelerinde en yüksek değer kontrol grubunda bulunmuştur. S150 grubundaki büyüme oranı S300 grubundan daha yüksek bulunmuştur.
