Abstract: Effective concentrations of methylpentynol for anesthetizing rainbow trout, brown trout, brook trout, and lake trout were determined by a series of tests. Concentrations of 1.5 to 8 parts per thousand induced anesthesia in 4 to 57 minutes. Increase in water hardness had no significant effect on the rate of anesthesia. Repeated anesthesia had little effect on rate of response. The efficacy of anesthetic solutions was reduced by continuous use. Methylpentynol may be more appropriate as a sedative or soporific for salmonids than as an anesthetic. |
