Effects of hypoxia, anoxia, and endogenous ethanol (EtOH) on selected temperature (Tsel) and activity in goldfish were evaluated. Blood and brain EtOH concentrations ([EtOH]) and brain oxygen partial pressure ( P O 2 ) were quantified at crucial ambient oxygen pressures. Below a threshold value near 31 Torr, Tseldecreased as a function of environmental P O 2 . Tselof 15°C-acclimated fish was ∼10°C at the onset of anoxia and changed little over 2 h. Activity showed a similar response pattern. Brain [EtOH] was significantly elevated above control levels after 1 h anoxia. In normoxic water, Tselremained different in previously anoxic and normoxic control fish for ∼20 min. Blood [EtOH] of previously anoxic fish remained significantly elevated ([EtOH] >4.0 μmol/g blood), and activity was significantly depressed at 20 min. Brain P O 2 reached normal levels in <3 min. We conclude that [EtOH] (brain or blood) and brain P O 2 are not proximal causes of either behavioral anapyrexia (hypothermia) or inactivity in goldfish exposed to oxygen-depleted environments.
