Summary

Benthic marine species abundance data from surveys undertaken in the Isle of Man. 9999 denotes colonial species. Between 1938 and 1952, Norman Jones (a benthic ecologist based at Port Erin Marine Laboratory (PEML))collected over 200 benthic samples from all around the south of the Isle of Man. Many of these samples pre-date the start of the commercial scallop fishery, so provide an important baseline with which to compare present day benthic fauna. Seven sites, where Jones recorded the highest density of samples, were selected and re-sampled during 1998-1999. Community composition and sediment size had changed at all sites. Mobile, robust and scavenging taxa had increased in abundance while slow moving, sessile and fragile taxa had decreased in abundance. Differences between historical and modern samples were greater than could be accounted for by natural variability of the system and indicate real long term change.
