Indução anestésica de Rhamdia quelen e Ctenopharyngodon idella com o óleo essencial de Ocimum micranthum

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO:

Os anestésicos são eficazes para reduzir ou minimizar o estresse nas operações de manuseio relacionadas à piscicultura. Com o objetivo de evitar efeitos residuais de fármacos sintéticos, vários agentes naturais, como óleos essenciais (OEs), têm sido testados. O objetivo deste estudo foi determinar a concentração ótima do OE de Ocimum micranthum para a indução de anestesia em juvenis de jundiá (Rhamdia quelen) e carpa capim (Ctenopharyngodon idella). Os resultados demonstram que a concentração mais adequada para sedar jundiás e carpas capim é 25μL/L. Enquanto que para anestesiar 200μL/L é mais adequado para jundiás e 100μL/L para carpas capim, pois essas concentrações induzem anestesia profunda em menos de três minutos e recuperação em menos de cinco minutos. A análise dos constituintes do OE identificou o metil chavicol, um composto com potencial carcinogênico, como componente majoritário (58,2%). Portanto, o OE de O. micranthum não é recomendado para anestesia de peixes usado como alimento.

Palavras-chave:
anestesia; jundiá; carpa-capim; sedação

Table 1
Relationship between the essential oil concentration of Ocimum micranthum and the time required to reach each stage of anesthetic induction and recovery in Rhamdia quelen. x=concentration of essential oil (μL/L); y=time required for the stages of anesthetic induction in seconds. Different letters in the column “Recovery” indicate significant difference between concentrations. Evaluation of anesthetic activity was performed by regression analysis (concentration of the EO x time to induce sedation, slight and deep anesthesia, or recovery). When no significant relationship was reported, concentrations were compared by one-way ANOVA followed by Tukey's post hoc test. Differences were considered significant at P<0.05. Data are presented as the mean±SEM.
