AREA SWEPT

area swept: translation

the area of the sea floor over which the fishing gear such as a trawl is dragged during its operation. The area is equal to the effective horizontal opening of the gear multiplied by the distance the gear has covered during the period of time considered, e.g. during a one hour trawl haul. Combined with information on the fish quantities caught during the considered time period, the area swept allows an estimation of a relative or absolute value of the fish density (and biomass) in the area

area swept: translation

In reference to a demersal trawl, it is the area of the sea floor over which the net is dragged during its operation, and is estimated by multiplying the width of the net mouth by the distance the net is dragged. From data on the densities of fish caught in a unit area swept, an estimate of the biomass in that part of the sea can be obtained.
