The aim of a demersal bottom trawl survey is to collect standardized fishery-independent data with a view to improving stock assessments. Demersal bottom trawl surveys should contribute to the characterization of fishery resources in a given area, in terms of population distribution (e.g., relative abundance indices) and demographic structure (e.g., length and sex distributions) as they collect data, including sex, maturity and weight, for the estimation of growth parameters of priority species.  2, record 1, English, - demersal%20bottom%20trawl%20survey

Bottom-contact fishing gear has impacts on benthic populations, communities, and habitats. The effects are not uniform, and depend on at least the specific features of the seafloor habitat, including the natural disturbance regime; the species present; the type of gear used; the methods and timing of deployment of the gear; and the frequency with which a site is impacted by specific gears.  1, record 2, English, - bottom%2Dcontact%20fishing%20gear

Demersal fisheries use a wide variety of fishing methods to catch fish and shellfish on or close to the sea bed. Demersal fisheries are defined by the type of fishing activity, the gear used and the varieties of fish and shellfish [that] are caught.

Among the fish there are two essentially different habits; those that live near the bottom are called demersal fish, and those that have no connection with the bottom are called pelagic. Demersal fish may look much like pelagic fish or they might have specific physical adaptations to bottom living. In either case the type of bottom sediment, its texture and composition, may be important to demersal fish, who generally feed and lay their eggs on the bottom.  5, record 16, English, - demersal%20fish
