Description
Summary:The response of biochemical and hematological parameters were analyzed in dog snapper (Lutjanus jocu) grown in net cages, as well as for the specimens kept in the laboratory during an infestation by Neobenedenia melleni, and after treatment with freshwater bath and injectable application of levamisole. Significant changes were observed in N. melleni parasitized individuals, characterized by increased glucose and lactate levels, as well as a significant fish hematocrit reduction and leukocyte increase. Treatment with freshwater baths, concomitant with injectable levamisole application, showed therapeutic efficacy in several parameters after 14 days of treatment. Key words: aquaculture, biochemistry, hematology, Neobenedenia melleni, fish. A resposta de parametros bioquimicos e hematologicos foram analisadas no dentao (Lutjanus jocu) cultivados em tanque- rede, bem como os exemplares mantidos em laboratorio durante a infestacao por Neobenedenia melleni e apos o tratamento com banho de agua doce e aplicacao injetavel de levamisol. Foram observadas alteracoes significativas nos individuos parasitados por N. melleni, caracterizado pelo aumento dos niveis de glicose e lactato, bem como significativa reducao em hematocrito e aumento em leucocito dos peixes. O tratamento com banhos de agua doce, concomitante a aplicacao injetavel de levamisol, evidenciou eficacia terapeutica em diversos parametros apos 14 dias de tratamento. Palavras-chave: aquicultura, bioquimica, hematologia, Neobenedenia melleni, peixe.
