It will gather all of the shells,regardless as to whether they are opened or closed, whilethe crow-foot dredge can only catch the ones that areopened. Then, too. it is probable that a dredge hookmay sometimes pull a pearl from the posterior portionof the shell and lose it in the mud without even catchingthe mussel.
