Pelagic trawl

Pelagic, or midwater trawls have a cone-shaped body and a closed ‘cod-end’ that holds their catch.

Pelagic trawls are generally much larger than bottom trawls and can be towed by one or two boats (pair trawling). They are designed to target fish in the mid- and surface water, such as herring, hoki and mackerel. Acoustic technology is used to locate the position and depth of the target fish and the path of the boat(s) and trawls are adjusted accordingly.

Midwater trawls have no contact with the seabed. They are occasionally associated with the incidental catch of non-target species (bycatch). MSC certified fisheries take measures to minimise bycatch through the use of specific mesh sizes, exclusion devices and acoustic deterrents such as 'pingers'.
