General discription

STIPED (STImulation Excluder Device) – As roundfish tend to stay clear off any netting during the fishing process, several studies have reported the effectiveness of escape windows in the upper panel of the extension of a trawl to be very limited. The idea of STIPED is to use ropes with floats (a) to stimulate roundfish to perform upwards escaping reactions in the vicinity of the escape window (b). The device raises the escapement rate while keeping catches of flatfish. In addition to the study presented below, aiming at an avoidance of all cod, Herrmann et al. (2015) were able to proof the efficiency of STIPED for releasing undersized cod.
