To determine the anesthetic effects of various concentrations of 2-PE on Munzur trout fingerlings, the experiments were performed in two different temperatures (13 &ordm;C and 18&ordm;C) and five different concentrations (0.1, 0.2, 0.3, 0.4 and 0.5 ml L^-1). 2-PE was used in this study as an anesthetic agent. In the anesthetic processing we practiced in all concentrations, except for 0.1 ml L^-1 of 2-PE, loss of reflex (S5) was determined between 68 sec and&nbsp; 276 sec, and total behavioral recovery (R3) was determined between 58 sec and 208 sec. Induction times of anesthesia varied with anesthetic concentrations, decreasing with the increases of 2-PE concentrations. On the other hand, recovery times increased with decreasing of anesthetic concentrations. The lowest effective dose was determined as 0.3 ml L^-1 at the temperatures 13 &ordm;C and 18&ordm;C. In this study, first time optimum anesthetic doses of 2-PE were determined for fingerling specimens of <em>Salmo munzuricus </em>which is endemic to Munzur stream and has an importance for aquaculture.
