We studied the reproductive behaviour of a common European freshwater clam, Anodonta piscinalis Nills., a generalist with respect to habitat and range of hosts. In a laboratory experiment, we found that female clams released more glochidia when in the presence of a fish, suggesting that they recognized its presence. In a second experiment, clams responded positively but nonspecifically to tactile, chemical and visual stimuli that might indicate the presence of a fish.
