The Effects of Different Natural Anesthesia on Survival of Juvenile Sang kuriang Catfish (Clarias gariepinus) on Closed Wet System Transportation

Abstract

This research aims to understand the effect of the different natural anesthesia on the survival rate of sangkuriang catfish juvenile which was transported using closed wet system fish transportation. We discussed selected natural anesthesia for effectiveness, induction times and recovery times in the application of anesthesia for transportation. The benefits of this research were as a reference to choose the best natural anesthesia for catfish juvenile transportation. This research used the experimental method on Completely Randomized Design (CRD) with 4 treatments (clove oil, nutmeg oil, lemongrass oil, and control) with 3 replications. Measured parameters were survival rate after fish transportation, survival rate after aquaculture for 7 days, induction times, recovery times,and water quality such as temperature, dissolved oxygen (DO), pH, and ammonia. The result was clove oil had high survival rate after fish transportation and cultivated for 7 days which is 98,67% and 87,33%. This treatment had quicker time for induction of catfish juvenile than other treatments which was 12.59 minutes although recovery time (10.34) minute was assumed lower than other treatments.
