Oxygen consumption of Astyanax sp. as function of temperature and oxygen concentration
Abstract
Freshwater species are expose to periodic environmental variations such as oxygen concentration and temperature, reflecting on physical, chemical and biological process. These variations can reflect directly on the fish’s distribution. As response, these organisms are induced to develop morphological and physiological responses as alternative strategic to the environmental fluctuations. The aim of this study was to investigate the oxygen consumption of Astyanax sp., after exposing the organisms in two differently temperature treatments (22º C e 29º C). Temperature shows a significantly effect on fish’s oxygen consumption where, under normoxia and lower temperature (22ºC), fishes didn’t show any saving of oxygen. In other hand, under higher temperature (29ºC), a reduction of oxygen consumption was detected as response to a low oxygen concentration on the water. However, we conclude that temperature and oxygen concentration can influence on physiological and adaptive mechanisms under extreme environmental conditions.
