General Biology Additional InformationCan be found in very high densities, for example when forming a reef. Typically found in lower densities as a crust or as individuals. At the Bristol Channel location studied by George & Warwick (1986), densities in excess of 4,000/m² for loosely aggregated Sabellaria spinulosa were recorded whilst the area sampled by Hiscock & Rostron (unpublished) on a level hard substratum had a single layer crust with 9,561 individual Sabellaria spinulosa in 1.4m². There has been considerable concern about decline in Sabellaria spinulosa reefs and shrimp fisheries have been implicated in the decline. However, Vorberg (2000) could find no damage caused after experiments with shrimp trawls in the Wadden Sea and suggests that declines might be more associated with changing patterns of currents perhaps associated with construction, dredging and dumping.
