Catch rates were compared between gillnets with and without bait in the Greenland halibut Reinhardtius hippoglossoides (Walbaum) fishery off Baffin Island, Canada. Two different types of baiting techniques were compared: bait bags where squid were placed into 2‐mm mesh bags, and tied bait where squid were tied into meshes. Both types of baited gillnets significantly increased the capture of the target species, Greenland halibut, with increases of 253.8% and 149.7% for the bait bag and tied bait, respectively. Common bycatch species showed mixed effects, with roughhead grenadier Macrourus berglax Lacépède showing no increase in catch per unit effort (CPUE) for either bait type (p > 0.05), and porcupine crab Neolithodes grimaldii (Milne‐Edwards and Bouvier) only had a higher CPUE with baited gillnets when bait bags were placed on the footrope. Less common bycatch species—but with threatened populations—showed an increase in CPUE, including Greenland shark Somniosus microcephalus (Bloch and Schneider) and Northern wolffish Anarhichas denticulatus Krøyer. Baiting gillnets affected the CPUE of gillnets in the Greenland halibut fishery, and management should consider how the increased CPUE of both target and bycatch species are affected by this new fishery trend.

诱饵刺网在加拿大格陵兰大比目鱼渔业中的作用

比较了加拿大巴芬岛附近格陵兰大比目鱼Reinhardtius hippoglossoides（Walbaum）渔场中有和没有诱饵的刺网捕获率。比较了两种不同类型的诱饵技术：将鱿鱼放入2毫米网眼袋的诱饵袋，以及将鱿鱼绑在网眼中的绑好的诱饵。两种诱饵刺网都显着增加了对目标物种格陵兰大比目鱼的捕获，诱饵袋和绑好的诱饵分别增加了253.8％和149.7％。常见的兼捕种类表现出不同的效果，其中两种诱饵类型（p  > 0.05）和豪猪蟹Neolithodes grimaldii的粗制榴弹兵Macrourus berglaxLacépède的单位捕获量（CPUE）均未增加。（Milne-Edwards和Bouvier）将诱饵袋放在脚踏板上时，只有带诱饵刺网的CPUE较高。较不常见的兼捕物种（但种群受到威胁）显示CPUE有所增加，包括格陵兰鲨鱼Somniosus microcephalus（Bloch和Schneider）和北狼鱼Anarhichas denticulatusKrøyer。诱饵刺网影响了格陵兰大比目鱼捕捞中刺网的CPUE，管理者应考虑这一新的捕捞趋势如何影响目标和兼捕种类的增加的CPUE。
