Seed scallops, with a small amount of white worm tube (Serpula) attached to the shell. These scallkops have not yet spawned, and, for the future welfare of the scallop fishery, should be protected until they have passed the spawning period, which occurs when the scallop is one year old. The capture of these immature scallops is a decided menace to the fishery, and is forbidden by law.
