Trawl Catches

The distribution and relative abundance of macroepibenthic echinoderms in the eastern English Channel and Irish Sea is described from beam trawl catches. Echinoderms accounted for approximately 29% (by biomass) of fauna captured. A total of 24 species were recorded, including 12 species of starfish. The most frequently encountered species were Asterias rubens and Psammechinus miliaris, which were recorded at 85.5% and 56.0% of stations respectively. Asterias rubens and Ophiothrix fragilis accounted for 63.7% and 25.5% (by biomass) respectively of the echinoderms sampled. Mean echinoderm catches ranged from 0.8-kg h−1 in the north-eastern English Channel to 329-kg h−1 in the south-eastern Irish Sea. The echinoderm fauna was more diverse in the St George's Channel and western Irish Sea (6.7–7.0 species haul−1) than in the north-eastern English Channel (1.9 species haul−1).

Box Corer

Between 1983 and 1989,66 stations in the north-eastern Irish Sea offshore from Sellafield, Cumbria, were sampled by Reineck box corer to assess the abundance and distribution of the benthic macro-infauna. A total of 40 taxa was identified, of which the predominant group was polychaetes. Cluster analysis of the abundance data showed a division into three station clusters. Simple discriminant analysis showed that the three clusters were correlated (P<0.01) with sand, silty sand and sandy silt sediments. However, the three station groups did not show any clear pattern of characterizing taxa with sediment classification. The bioturbating potential of each taxon is reviewed. A method of weighting abundance data by a factor representing an estimate of individual taxon bioturbating potential is also suggested. This technique is illustrated and discussed by using the weighted data in a further cluster analysis to identify probable areas of high inf aunal bioturbation off Sellafield.

Transport And Mixing

In September 1993 the Irish Sea floor near the Sellafield nuclear reprocessing plant was surveyed by towed video to assess the distribution, abundance and behaviour of large burrowing invertebrates believed to be important in the transport and mixing of radionuclide-contaminated sediments. Sixteen stations were surveyed, covering a range of sediment types. Burrow openings and mounds were counted and assigned to species where possible. Particular attention was paid to the similarities and differences between the features observed and those produced by the same species in Scottish sea lochs, the source of most relevant ecological data. Several different burrowing communities were identified from bottom topography. Offshore muddy sands supported dense populations of the thalassinidean crustacean Callianassa subterranea, in burrows similar to those described from the North Sea. Coarse sediments closer inshore had C. subterranea at lower density, with the thalassinidean Upogebia deltaura and the crab Goneplax rhomboides also present. Softer muds were dominated topographically by ejecta mounds of the echiuran Maxmuelleria lankesteri and burrows of the Norway lobster Nephrops norvegicus. The thalassinideans C. subterranea, Jaxea nocturna and Calocaris macandreae were also present at low density. Surface bioturbation features in this habitat were very similar to those described from sea lochs. Population densities estimated from surface bioturbation features were always lower than counts of specimens from box-cores. The visual survey therefore gave minimum estimates of population density. Available data on rates of bioturbation by the species concerned are collated to give rough estimates of biogenic sediment transport in the habitats surveyed.
