A COMPARATIVE STUDY OF THE RESPIRATORY METABOLISM OF EXCISED BRAIN TISSUE OF MARINE TELEOSTS

Abstract
1. The oxygen consumption of brain tissue of 17 species of marine teleost fishes was determined at 30° C. 2. A positive correlation exists between rate of oxygen consumption and activity of fishes. The more active fishes, like the menhaden, had a higher Qo2 then the sluggish fishes, such as the toadfish. 3. In general, when comparing results of this paper with various physiological indices of activity, a positive relationship was noted. 4. Qo2 of brain tissue of the pinfish and the toadfish were independent of body weight and body length.
