Anesthetic Activity of Camphor (Cinnamomum camphora) Essential Oil on Goldfish at Different Water Temperatures

Abstract

In this study, it was aimed to investigate the anesthetic effects of camphor essential oil on goldfish at different water temperatures and to investigate the combined effect of anesthetic concentration and water temperature on duration. While the most effective concentration in terms of deep anesthesia was 300 µl/lt at all water temperatures, the most optimal concentration when full recovery was considered was 250 µl/lt. As the anesthetic concentration increased, deep anesthesia times were shortened, and full recovery times were prolonged. Anesthesia and recovery times were recorded to be longer at low water temperatures compared to high water temperatures. A weak neg-ative relationship was found between deep anesthesia and full recovery times at 14°C water temperature, a strong negative relationship at 18°C water temperature and a negative relationship at 22°C water temperature. A strong negative relationship was found between deep anesthesia times and concentrations at all water temperatures, while a strong positive relationship was found between full recovery times and con-centrations. It was also observed that concentration and water temperature had a combined effect on the duration. In conclusion, camphor essential oil is an effective anesthetic agent in goldfish at three different water temperatures.

Kafur (Cinnamomum camphora) Esansiyel Yağının Farklı Su Sıcaklıklarında Japon Balıkları Üzerindeki Anestezik Etkinliği

Abstract

Bu çalışmada, Japon balıklarında kafur esansiyel yağının farklı su sıcaklıklarında anestezik etkilerinin incelenmesi ve anestezik konsantrasyonu ile su sıcaklığının süre üzerine birleşik etkisinin incelenmesi amaçlanmıştır. Bütün su sıcaklıklarında derin anestezi bakımından en etkili konsantrasyon 300 µl/lt olurken, tam iyileşme dikkate alındığında en optimal konsantrasyon 250 µl/lt olmuştur. Anestezik madde kon-santrasyonu arttıkça derin anestezi süreleri kısalmış, tam iyileşme süreleri ise uzamıştır. Yüksek su sıcaklıklarına kıyasla düşük su sıcaklıklarında anestezi ve iyileşme süreleri uzun kaydedilmiştir. Derin anestezi ve tam iyileşme süreleri arasında 14°C su sıcaklığında zayıf negatif ilişki, 18°C su sıcaklığında kuvvetli negatif ilişki ve 22°C su sıcaklığında negatif ilişki bulunmuştur. Derin anestezi sü-releri ve kon-santrasyonlar arasında tüm su sıcaklıklarında kuvvetli negatif bir ilişki saptanırken, tam iyileşme süreleri ve konsantrasyonlar arasında kuvvetli pozitif bir ilişki tespit edilmiştir. Konsantrasyon ve su sıcaklığının süre üzerine birleşik etkisinin de olduğu saptanmıştır. Sonuç olarak, kafur esansiyel yağı Japon balıklarında üç farklı su sıcaklığında etkili bir anestezik maddedir.
