Wooden tags used when catching sea bream

These wooden tags are used to encourage tai sea bream to gather in one place. By dredging the sea bottom with the tags to force up sediment, the sound of the tags clacking together and swaying light confuses the fish and makes them come together, making them easier to catch.
