Scallop fishing vessel activity 2012 to 2022
Welsh Government
This layer represents the total scallop fishing vessel activity over the 2012 to 2022 scallop fishing seasons. The scallop fishing season runs from 1st November to 30th April.
Since 2012, vessels fishing for scallops in the Welsh scallop fishery have been required to install a Vessel Monitoring System (VMS). The VMS records the location, speed, and heading of the vessel. Each record is referred to as a "ping". We have filtered the data to remove any “pings” where vessels are not fishing. We have assumed that vessels are fishing when travelling between 1 and 4 knots, and that no fishing occurs within 1km of ports.
We have aggregated the filtered data to show the number of pings per 0.01 degree grid cell. In order to protect the anonymity of fishers, no data is shown for cells containing data from less than 3 vessels.
