| Abstract | At temperate latitudes, mass of the soft parts of bivalve molluscs generally declines during winter. Long-term field data collected in the western part of the Dutch Wadden Sea indicate that losses are more substantial during mild than during cold winters. Moreover, food supply appears to be involved. We tried to find experimental evidence to prove that the correlative relationships observed in the field are based on cause-effect relationships. To this end, three common intertidal bivalves, the common cockle Cerastoderma edule, the common mussel Mytilus edulis, and the Baltic tellin Macoma balthica were subjected to manipulated water temperatures and immersion (feeding) times during the first half of 2 years (the end of December till spawning). Water temperatures were kept either at outdoor values or were lowered by a few degrees. In all three species, higher water temperatures and shorter daily feeding periods resulted in faster body-mass declines in winter and slower subsequent growth in spring than lower temperatures and unrestricted feeding times. |
