Scallop Tagging Project – Orkney Fisherman Association
Scallop divers in Orkney often observe that targeted areas can be re-populated over quite short time periods, faster than can be accounted for by growth of undersized stock alone. This suggests that scallops may be less sedentary than might at first appear, which could be an important factor in defining the relationship between the fishery and the stock. OFA and Heriot-Watt University have been working together on a project funded by Marine Scotland, putting tags on scallops to determine just how far they move. At scales of 100m or less, it appears that up to around half the scallops in an area are likely to be replaced over the course of a month. More than 2,000 tagged scallops are now distributed around Orkney waters, and we’re now keen to hear of any recaptures that will provide information on larger scale movements.
