The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Scottish West Coast Survey. The Quarter 1 Scottish Groundfish survey started in 1981 and was initially intended to cover the fishing grounds on the continental shelf to the west of Scotland; in 1996 the survey area was extended to include the northern Irish Sea.
