Human-wildlife Interactions at Sea (2017-2018)

The pelagic longline fishery in the mid-Atlantic region of the U.S. is embedded in long-standing cultural ties to place, identity and livelihoods. This fishery also experiences serious problems with marine mammal depredation of bait and catch, and incidental capture of short-finned pilot whales (Globicephala macrorhynchus).

This project addressed the critical intersection of whale conservation and traditional livelihoods by studying the history and dynamics of human-wildlife interactions in the pelagic longline fishery from ecological, behavioral, social and institutional perspectives.

The aim of the project was to better understand the history and dynamics of interactions between fishermen and the pilot whales that depredate the fishermen’s catch and occasionally become entangled in their gear. The team assessed how fishers’ behavior has adapted in response to conflict with the whales, how whales modify their behavior to interact with the fishery and how regulatory frameworks have shaped these interactions.

To identify potential solutions to the depredation problem, the team used a diverse set of approaches, including geospatial analysis, interviews with fishers, ethnographic observation of key stakeholder meetings and institutional analysis of regulations.

Team members conducted a geospatial analysis using satellite telemetry data from over 50 tagged pilot whales and locations of longline sets from Vessel Trip Reports and interviewed longtime fishermen along the U.S. East Coast. Team members also attended stakeholder meetings convened by the federal National Marine Fisheries Service and used ethnographic methods to understand how different stakeholders represent conflicts with pilot whales and interact with one another.

Team members also analyzed regulatory documents to examine how regulations have changed over time and the effects on human-whale interactions.
