Global analysis of response and recovery of benthic biota to fishing
Towed bottom-fishing gears are thought to constitute one of the largest global anthropogenic sources of disturbance to the seabed and its biota. The current drive towards an ecosystem approach in
A quantitative analysis of fishing impacts on shelf-sea benthos.
It is shown that inter-tidal dredging and scallop dredging have the greatest initial effects on benthic biota, while trawling has less effect, and fauna in stable gravel, mud and biogenic habitats are more adversely affected than those in less consolidated coarse sediments.

Chronic fishing disturbance has changed shelf sea benthic community structure
Evidence is presented that chronic bottom-fishing disturbance has caused significant and widespread changes in the structure of two distinct soft-sediment benthic assemblages and habitats and that the communities within these areas currently may be in an alternative stable state.
Modification of marine habitats by trawling activities: prognosis and solutions
Fishing affects the seabed habitat worldwide on the continental shelf. These impacts are patchily distributed according to the spatial and temporal variation in fishing effort that results from
Chronic bottom trawling alters the functional composition of benthic invertebrate communities on a sea-basin scale
It is demonstrated that chronic bottom trawling can lead to large scale shifts in the functional composition of benthic communities, with likely effects on the functioning of coastal ecosystems.
Trawl disturbance on benthic communities: chronic effects and experimental predictions.
The results presented indicate that otter-trawl impacts are cumulative and can lead to profound changes in benthic communities, which may have far-reaching implications for the integrity of marine food webs and is an important step toward understanding the global ecosystem effects of bottom trawling.
Cumulative impacts of seabed trawl disturbance on benthic biomass, production, and species richness in different habitats
A large-scale assessment of bottom trawl fishing of benthic fauna in different habitats was conducted, using a theoretical, size-based model that included habitat features and demonstrated that trawling reduced biomass, production, and species richness.
The effects of beam-trawl disturbance on infaunal communities in different habitats
This study investigated its local impact on an infaunal community in the north-eastern Irish Sea and found no difference between fished and unfished areas, which suggests that the effects of fishing disturbance are consistent between replicate samples.
