Abstract
Canterbury mudfish (Neochanna burrowsius) were held in small respirometer chambers with a rubber dam separating head and body. Oxygen uptake by the head and by the body were determined in water and in air. In both media cutaneous O2 uptake is a significant component (>43%) of total O2 consumption (VO2). In air, more carbon dioxide was lost to the body compartment than to the head compartment. With the head in air and the body in hypoxic water (PO2 2 to the water over 2 h, and VO2 was maintained by an increase in O2 uptake by the head.
