Abstract
DOES any one know what happens to the pearl mussel (Margaritana margaritifera) between the glochidium falling off the trout, etc., and the big adult mussel? No one seems to have seen young individuals, and the ordinary specimens which are found are never less than about 3 inches long and must be several years old. I have lately had another vain hunt for young ones in the Herefordshire Wye, so far as it is accessible by paddling; presumably they live somewhere in deep water, and not in the shallows where the adults are. The revival of the pearl fishing in recent years may have led some one to work out the life history: its investigation might be a grateful occupation for summer holidays.
