The University of Liverpool, at Port Erin Marine Laboratory (PEML), carried out an experiment to compare community composition in areas of high and low scallop dredging effort. Four pairs of sites were sampled on three of the main commercial fishing grounds. Each pair consisted of a 'high' and a 'low' effort area that were geographically close. The sites were to the north-west (Targets), south-west (Chickens A and C) and south-east (Douglas) of the Isle of Man. C.

The sites were to the north-west (Targets), south-west (Chickens A and C) and south-east (Douglas) of the Isle of Man. 24 infaunal grabs, nine sediment grabs and six beam trawl samples were taken per site (the same as the historical comparison). 9999 denotes colonial species.and 'Douglas' sites were sampled Four times, spring 1998, 1999 2000 and autumn 1999. 'Targets' was only sampled once in spring 1998 (only with beam trawls). 'Chickens C High' was never sampled due to bad weather and lack of boat time.
