Benzocaína sobre respostas ao estresse do matrinxã submetido ao transporte em sacos plásticos Benzocaine on the stress response of matrinxã subjected to transport in plastic bags

Abstract

O transporte é uma prática de manejo necessária em todas as estações de piscicultura. Entretanto, tal evento é um estímulo adverso e agudo, que interrompe o equilíbrio dos animais com o ambiente, de forma a promover o estresse. Alguns peixes de importância comercial, como o matrinxã (Brycon amazonicus), apresentam movimentação excessiva durante o manejo em geral, o que pode ocasionar consequências indesejáveis como perda de muco, de escamas, ferimentos e mortalidade. No presente trabalho, foi testado o anestésico benzocaína adicionado à água de transporte, como forma de reduzir estresse. Foram testadas duas concentrações de benzocaína, 10 e 15mg/L. Os resultados não mostraram efeitos de diminuição de estresse, apesar de a utilização da benzocaína ter reduzido a movimentação dos animais durante o transporte. As concentrações testadas podem ter aumentado o estresse por sofrimento respiratório, entretanto, o equilíbrio hidroeletrolítico não foi alterado, com sugestão de ação do anestésico sobre a liberação de catecolaminas.Transport is a necessary procedure in fish farming. However, it is an adverse and acute stimulus that breaks the balance between fish and environment, starting the stress condition. Some economic relevant species, as “matrinxã” (Brycon amazonicus), present excessive movements in handling, which may result in the unwanted consequences as loss of mucus, scales, injuries and death. In this work, the addition of the anesthetic benzocaine to the transport water was evaluated in juvenile “matrinxã”, in order to still the fish and possibly reducing stress. Two concentrations of benzocaine (10 and 15mg/L) were tested. The results did not show any diminution of indices related to stress, notwithstanding the use of benzocaine during transport. Concentrations tested increased the stress responses by respiratory affliction, however, hydro-electrolytic balance was unaltered, being suggested some effect of the anesthetic on the catecholamine releasing.
