Fig. 3. The effect of ArA, ASA and net confinement on plasma lactate levels. Samples were taken from non-stressed fish (t=0) and at intervals after confinement (t=20 min, 60 min, and 24 h). Open circles, low-ArA; filled circles, low-ArA + ASA; open triangles, high-ArA; filled triangles, high-ArA + ASA. ASA-treated fish were subjected to confinement 4 h after the last dose of ASA. Values are means ± S.E.M., N=10.
