In the Northeast Atlantic deep-water shrimp (Pandalus borealis) trawl fishery, the bycatch of juvenile fish and shrimp represents a problem. This study evaluated if inserting a 200 mm mesh size top-panel in the last three sections of the tapered upper belly section of the trawl could reduce bycatch of juveniles while maintaining the catch efficiency for deep-water shrimp. The bycatch species investigated were Greenland halibut (Reinhardtius hippoglossoides), redfish (Sebastes spp.) and polar cod (Boreogadus saida). The bycatch of Greenland halibut and the smallest polar cod was significantly reduced, while no effect was found for redfish. The large mesh panel did not lead to a significant loss of deep-water shrimp. The results of this study illustrate how a simple modification of a fishing gear can mitigate the bycatch problem in a shrimp fishery, without significant losses of the target species.

在东北大西洋深水虾（北极甜虾）拖网渔业，稚鱼和虾的兼捕代表的问题。这项研究评估了是否在拖网的上腹部锥形区域的最后三个区域中插入200 mm筛孔大小的顶板可以减少幼鱼的副渔获物，同时保持深水虾的捕捞效率。调查的副渔获物种类包括格陵兰大比目鱼（Reinhardtius hippoglossoides），红鱼（Sebastes spp。）和极地鳕鱼（Boreogadus saida）。格陵兰大比目鱼和最小的鳕鱼的副渔获物明显减少，而对红鱼则没有影响。大的网状面板并未导致深水虾的大量损失。这项研究的结果表明，对渔具进行简单的修改如何减轻对虾捕捞中的兼捕问题，而不会造成目标物种的大量损失。
