Effect of three different codend designs on the size selectivity of juvenile cod in the Barents Sea shrimp trawl fishery
Herrmann, Bent; Sistiaga, Manu Berrondo; Larsen, Roger B.; Brinkhof, Jesse (Journal article; Peer reviewed, 2019-11)Shrimp trawlers often use a Nordmøre sorting grid ahead of a small mesh codend to avoid bycatch of juvenile fish while allowing shrimps to be efficiently caught. However, small fish can pass through the grid to enter the ... -

Escape rate for cod (Gadus morhua) from the codend during buffer towing
Brinkhof, Jesse; Herrmann, Bent; Larsen, Roger B.; Sistiaga, Manu Berrondo (Journal article; Peer reviewed, 2017-10-04)The high abundances of Northeast Arctic cod (Gadus morhua) in the Barents Sea have led to the development of a new fishing tactic called buffer towing.
