Abstract: Ketamine was evaluated as water-soluble anesthetics drug for a species of fish, rainbow trout (Oncorhynchus mykiss). Fish (size ~20 - ~240 gr.) were exposed to a 100-ppm concentration of Ketamine solution (dissolved in water), they were arranged in 4 treatments based on their weight range (Treatment-1= 22.8±3.4 g; Treatment-2= 51.7±4.4 g; Treatment-3= 69.8±5.2 g and Treatment-4= 243.8±20.7 g). Elapsed time for anesthesia duration (stage1 to 3) and recovery duration was recorded. Also, surveillance was evaluated after recovery. Ketamine was effective to cause anesthesia in the fish as 100 ppm concentration. 10 fishes of each treatment (%100) were anesthetized and were induced in stageIII-Plane3 of anesthesia within 2-3 min after exposure to anesthetic solution (Treatment-1= 110.3±3.5 seconds; Treatment-2= 140.0±5.9 sec; Treatment-3= 180.0±5.8 sec and Treatment-4= 190.0±5.8 sec).
