1. 1.|Groups of Mytilus edulis and Anodonta cygnea were acclimated to either cold (5°C) or warm (17° or 20°C) temperatures for 30 days and then subjected to the following temperatures (5, 17 or 20, 28°C) for up to 21 days. 2. 2.|Serotonin, dopamine and norepinephrine concentratons of the CNS were determined spectrofluorometrically at various time intervals during the stress. 3. 3.|For both species heat stress increased serotonin and cold stress decreased it. The catecholamines showed transient cyclic changes for both treatments. 4. 4.|Monoamine levels in these species are quickly altered by temperature stress and the changes can be long lasting.
