| Abstract | The efficiency of benzocaine and menthol in rainbow trout males (Oncorhynchus mykiss) of three years old, with an average weight of 1,590 ± 0.2 g and a pattern length of 6.60 ± 2.3 cm was compare. In evaluation, it was consider three times: sedation (ST), manipulation (MT) and recovery (RT). Anesthetics were prepared from stock solutions: benzocaine: 12 g in a litter of alcohol and it was use in doses of 3 mL L of water. For menthol with 100 g L of alcohol and 1 mL L of water was use. Results with benzocaine were ST 225.50 ± 96 sec; MT 153 ± 37 sec and RT 325 ± 248 sec while in menthol it was obtain ST 244 ± 80 sec; MT 152.6 ± 37 sec and RT 399 ±163 sec. Organisms were sedate and recover faster with benzocaine. ANDEVA just pointed out significate differences (P<0.05) and in RT between treatments. Organisms sedation using both anesthetics allow manipulation during 152 sec, enough time for morphometric parameters determination or for other type of sampling like semen obtention, sanitary sampling, among others. With both treatments it was obtained an average of ST= 234 sec and in RT 362 sec. In any treatment, mortality was observe after 24 hours. Both anesthetics are available in markets and have low prices, so it was recommend in manipulation of this species with high commercial value. |
