متن کاملBottom-trawling along submarine canyons impacts deep sedimentary regimes
Many studies highlight that fish trawling activities cause seafloor erosion, but the assessment of the remobilization of surface sediments and its relocation is still not well documented. These impacts were examined along the flanks and axes of three headless submarine canyons incised on the Barcelona continental margin, where trawling fleets have been operating for decades. Trawled grounds alo...
متن کاملEffects of chronic bottom trawling disturbance on benthic biomass, production and size spectra in different habitats
Bottom trawling has widespread impacts on benthic communities and habitats. It is argued that the impact of chronic bottom trawling on benthic infauna depends on the natural disturbance levels to which benthic communities are adapted. We analysed biomass, production and size structure of two communities from a muddy and a sandy habitat, in relation to quantified gradients of trawling disturbanc...
متن کاملEffects of bottom trawling on the benthic assemblages in the south Adriatic Sea (Montenegro)
Trawling remains a controversial method of fishing due to the perceived lack of selectivity of the trawl net, which can result in the capture of a huge quantity and diversity of non-target species, including endangered species, and have a significant effect on the marine ecosystem (KUMAR & DEEPTHI, 2006). Trawl fishing has both direct and indirect impacts on the marine ecosystem as well as on b...
متن کاملImpacts of bottom trawling on deep-coral ecosystems of seamounts are long-lasting
Complex biogenic habitats formed by corals are important components of the megabenthos of seamounts, but their fragility makes them susceptible to damage by bottom trawling. Here we examine changes to stony corals and associated megabenthic assemblages on seamounts off Tasmania (Australia) with different histories of bottom-contact trawling by analysing 64 504 video frames (25 seamounts) and 70...
