Lineage Data Quality: The ICES recommended analysis requires the use of both VMS and logbook data to estimate the hours fished by each gear type per 0.05 × 0.05 degree grid cell (based on the ‘C-square’ coding system) per year. The gear–seabed interaction takes place at the scale of a fishing gear (e.g. metres). Although benthic features may occur at this scale, fishers deploy their gears at a scale of kilometres (e.g. length of the trawl track). The 0.05 × 0.05 degree grid cell is an appropriate scale to quantify the gear–seabed interaction. At this scale, several fisheries have been shown to be randomly distributed. The recommended annual temporal scale is based on the scale of recovery times of many parts of the benthos. All activities by fishing vessels other than active towing of gear should be excluded from the data. There are several techniques for excluding such activities; those handling the data should choose the technique that is most appropriate for the fishery concerned.
