Estimated number of total, recreational and commercial traps per day (1000) during the two-month lobster season (October–November) in 2008 for the study area in south Norway.

Unknown is traps which could not be allocated to neither recreational nor commercial due to unclear registration on buoy. Three weeks (4, 6 and 7) were not surveyed and estimates are based on the surveys before and after and therefore lack variance estimate [21].
