Farklı Öldürme Tekniklerinin Kahverengi Alabalık (Salmo trutta fario) Kan Biyokimyası Üzerine Etkileri

Abstract

Bu çalışmada, kahverengi alabalıklara (Salmo trutta fario) farklı öldürme teknikleri uygulanarak balıkların fizyolojik yanıtları bazı kan biyokimya enzimleri ile araştırılmıştır. Buzlu su, elektroşok, CO2, hipoksi ve kafasına vurma gibi farklı öldürme teknikleri, 75 balık kullanılarak denenmiş ve balıkların kan biyokimya parametrelerindeki değişim gözlemlenmiştir. Bu değişimlerde alkalin fosfataz (ALP) ve amilaz (AMS) istatistiki olarak önemsiz (p<0,05), kreatin kitinaz (CK) ve CK izoenzimlerinden olan CK-MB enzimi p<0,05 seviyesinde, alanin aminotransferaz (ALT), aspartat aminotransferaz (AST), gama glutamil transferaz (GGT) ve laktat dehidrogenaz (LDH) ise p<0,05’ de önemli bulunmuştur. Sonuçlar, öldürme tekniklerinin kahverengi alabalıklarda stres kaynağı olabileceğini ve fizyolojik durumlarında etkili olduğunu göstermektedir. Çalışma bulguları, daha kısa sürede sonuçlanan öldürme tekniklerinin hayvan refahı açısından daha uygun olduğunu göstermiştir.

The Effects of Different Stunning Techniques on Blood Biochemistry of Brown Trout (Salmo trutta fario)

Abstract

In this study, physiological responses of brook trout (Salmo trutta fario) were researched after the different stunning methods with biochemical enzymes. Icy water, electroshock, CO2, hypoxia, and head hitting were tried as stunning techniques to 75 fish and the alterations in the blood biochemistry parameters were analyzed. Alkaline phosphates (ALP), and amylase (AMS) were found as not statistically important, but alanine transaminases (ALT), aspartate transaminases (AST), creatin chitinase (CK), CK-MB (one of the CK isoenzymes), gamma glutamil transferase (GGT) and lactate dehydrogenase (LDH) levels were important (p<0.05). According to these results, the different stunning techniques affected the stress levels and physiological situations of brook trout. The study findings showed that killing techniques resulting in a shorter period were more suitable for animal welfare.
