Popis: Fish anesthesia is indicated to allow the accomplishment of several procedures such as biometry, tagging, transportation, physical examination, surgical procedures, and reproductive management. The doses of benzocaine in the carp anesthesia (Cyprinus carpio) were determined, carrying through six phases with 40 fish each. The average weight of carps in each phase was of 147.45±7.99g, 173.32±9.15g, 191.26±14.05g, 269.84±19.24g, 285.25±17.97g, and 300.91±16.45g. In each phase, fish had been captured and placed in four containers each one with different concentrations of benzocaine (100, 140, 180 and 220 mg/L respectively). The induction time (IT) was registered for each fish and after that the anesthetic induction biometry was performed. In each phase the minimal dose of benzocaine was calculated using the Linear Response Plateau (LRP), in a model that included dose and IT. The LRP was calculated for each phase: 125.79mg/L in 114.33s, 155.68mg/L in 115.75s, 145.33mg/L in 102.52s, 149.50mg/L in 140.53s, 166.42mg/L in 116.15s, and 158.34mg/L in 102.00s. The optimal dose was related with the weight, resulting in the equation: dose=114.230+0.158 x weight (r 2 =0.53). The equation shows that an increase in the weight in 1g
