Creel Fishing Effort Study - Average Number of Crab/Lobster Hauls Per Day and Average Number of Nephrop Hauls Per Day
Measuring fishing effort is important for assessing the environmental sustainability of fish stocks and the socioeconomic efficiency of fishing activity. Fishing effort describes the amount of fishing gear used on a fishing ground over a given unit of time. Effort in this case is defined as number of creels hauled per day per 4 km2. This survey interviewed 198 creel vessel skippers from four regions, two on the west and two on the east coast of Scotland. This analysis has been produced from these SAMPLED vessels only. This IS NOT a census and IS NOT a map of all creeling effort in these waters or in the survey areas. This is an indication of potential fishing effort only and if creeling is not quantified in an area in this map, that DOES NOT mean creeling is not taking place. Equally quantified effort could be higher given some creeling vessels were not surveyed. Fishing effort outside of the surveyed area was not measured.

Not Planned
Creel fishing effort areas obtained from interviews and stakeholder workshops were recorded as spatial features, digitised into ArcGIS on WGS84 datum by interviewers. Spatial features recorded as a one to many relationship with each vessel having at least one effort area. Values for effort were recorded alongside spatial areas in a spreadsheet by interviewers. Spatial data were transformed to ETRS 1989 Lambert Azimuthal Equal Area and a 2km by 2km grid was plotted to cover the 4 sample regions. A count of cells per effort area was used to produce an average haul per grid cell for each area. This was then combined with overlapping data to produce a sum of average haul effort per cell (per day).
