Entanglement in commercial fishing ropes threatens the recovery of the North Atlantic right whale Eubalaena glacialis , a species largely restricted to waters off of eastern North America. What happens when whales encounter fishing gear is complex and poorly understood. The goal of creating the case studies associated with our publication see: North Atlantic Right Whale Entanglement Case Studies on the Publications Page - scroll all the way down was to combine what we know to date on the individual whales entangled, the configuration of ropes entangling them, the extent of their injuries, and what can be learned about the gear retrieved from them. There is much to learn about the nature of these conflicts, and increasing our understanding about these events can help point to some of the more promising ways to avoid them or reduce their severity.

By the s, powerful trawlers equipped with radar , electronic navigation systems, and sonar allowed crews to pursue fish with unparalleled success, and Canadian catches peaked in the lates and earlys. The trawlers also caught enormous amounts of non-commercial fish, which were economically unimportant but very important ecologically. This incidental catch undermined the stability of the ecosystem, depleting stocks of important predator and prey species.
