“…This persistent disturbance to the benthic community from fishing may have altered the benthic fauna to form more resilient, disturbanceadapted communities (e.g. Kaiser et al 2000a,b); this proposition is partly supported by the few available long-term comparisons of early century and more recent benthic faunal composition (Rumohr & Kujawski 2000, Callaway et al 2007). Our results here suggest that even in areas that have been heavily fished for decades, infaunal benthic invertebrate communities may remain sensitive to increases in fishing intensity.…”

Demersal fishing alters seabed habitats and affects the structure and functioning of benthic invertebrate communities. At a critical level of disturbance, such communities may approach an equilibrium disturbed state in which a further increase in disturbance has little additional impact. Such arguments have been used to suggest that an ecosystem approach to fisheries management (EAFM) should protect lightly fished areas and deflect fishing activity into areas that are already intensively fished. In this study, the effects of variation in fishing disturbance on the secondary production, species diversity, abundance, biomass, and community structure of benthic infauna were examined in a region of the German Bight (North Sea) that has been intensively trawled for decades. Variation in fishing disturbance across the study area was determined using automated position registration and vessel monitoring through satellite. Even in such a heavily fished area, linear regression analyses revealed that biomass, species richness, and production decreased significantly with increasing fishing intensity. Although redundancy analyses (RDA) showed that sediment characteristics were influential in determining the structure of the infauna community, partial RDA revealed that fishing continued to have an impact on community structure in terms of biomass. These results suggest that, in implementing an EAFM, managers will need to consider the possibility that, even in areas with high chronic fishing disturbance, further increases in fishing activity may still cause additional damage to benthic invertebrate communities.

“…The positive correlation to trawling pressure was unexpected, as a previous study along the Kola transect showed a significant negative correlation between benthic biomass and bottom trawling (Denisenko 2001). Our findings probably relate to the fact that long-term bottom trawling changes the age and size spectrum of benthic communities from long-lived, large sized individuals to short-lived, smaller sized individuals and species (Callaway et al 2007), an effect also observed after ice scour disturbances (e.g. Conlan et al 1998).…”

“…Such species are dug out by the tickler chains and caught with the trawl. They are often difficult to assign to either an epi-or endobenthic lifestyle and were thus kept in the species list (similar to Callaway et al 2007). Table 2) appeared on all 14 cruises.…”

“…Subsequently, several studies of the epibenthos were performed covering the whole North Sea (Dyer et al 1983;Frauenheim et al 1989;Jennings et al 1999;Zühlke et al 2001;Callaway et al 2002Callaway et al , 2007Reiss et al 2010). Rees et al (1999) compared benthic in-and epifauna of an even larger research area, including parts of the North Sea, the English Channel, the Celtic and the Irish Sea in a period from 1992 to 1996.…”

The megaepifauna of the Dogger Bank (North Sea): species composition and faunal characteristics 1991–2008

During a long-term study in the summer months of the years 1991-2008, 176 megaepifaunal species were recorded through a series of beam trawl surveys on a grid of fixed stations on the Dogger Bank (central North Sea). This paper gives a qualitative overview on species composition throughout the research period, determined from samples collected during 15 cruises. In recent years, a number of species with more oceanic distribution patterns (e.g. species from SW British coasts) has been collected. In spite of these newcomers, there was a slight decrease in total species numbers during the research period.
