Pemanfaatan Minyak Cengkeh (Syzygium aromaticum) sebagai Biosedatif Alami untuk Meningkatkan Kelangsungan Hidup Benih Patin Siam (Pangasius hypophthalmus) selama Transportasi Sistem Tertutup

Abstrak

This study aimed to evaluate the effectiveness of clove oil (Syzygium aromaticum) as a natural anesthetic for closed-system transportation of striped catfish fry (Pangasius hypophthalmus). Three clove oil doses (4, 5, and 6 mL per container) were tested for induction time, anesthesia duration, and fish survival rate during eight hours of transportation. The results showed that the 5 mL dose was optimal, with an induction time of 0.38 ± 0.05 minutes, anesthesia duration of 120 ± 3.6 minutes, and a survival rate of 70%. The 4 mL dose produced the highest survival rate (83.3%) but showed less stable anesthetic effects, while the 6 mL dose reduced survival due to eugenol toxicity. Water quality parameters (temperature 28.8–30.7°C; pH 6.7–7.2; DO 6.2–7.3 mg/L) remained within optimal ranges. Therefore, clove oil is effective as a natural anesthetic to reduce stress and maintain the survival of striped catfish fry during closed-system transportation
