Instrument: Spat Bag

Mesh-netted bag used for collection of spat (juvenile scallops, oysters, etc.). Access to the bag is by a top opening held shut with a drawstring. Strips or panels of black plastic or cloth material, designed to attract spat, are placed into the fine-meshed bag. Bags are closed and hung underwater for a period of time to allow the spat to settle in the collection material. Further description provided here (PDF).
