Northeastern Arizona has experienced a recent increase in helium extraction activity. This qualitative case study articulates and explores various sociotechnical imaginaries – or, collectively produced social justifications for technological decisions and systems – that inform this new stage of underground helium extraction. Leveraging two years of interviews, document analysis, and participant observations to understand and interrogate the political and cultural origins of perceptions around helium extraction, I examined how these imaginaries and associated power dynamics influenced communication within and between stakeholder groups. In order to mitigate the power differentials between stakeholder groups, and put these imaginaries in conversation with each other, I led the development of a series of short videos that explain controversial technoscientific concepts from this research. These videos were produced in continuous collaboration with multiple disparate stakeholders, including activists, regulators, and industry members, in order to create a space for a productive conversation and reflection to explore tensions between conflicting points of view between stakeholders. This iterative work used the imaginaries of helium extraction in Arizona to produce a space for collective deliberation that can result in negotiated shared knowledge through brokered dialogue amongst these disparate groups and their competing visions of Arizona’s helium futures.

In recent years, the Maine lobster industry, researchers, and policy makers have attempted to come together to set new regulations into place that will help slow the decline of right whale populations off the North Atlantic coast. Like many species, right whales were once abundant in the Atlantic before commercial whaling practices decimated populations to near extinction by the 1900’s (Fujiwara et al., 2001). Today’s populations total to approximately 450 individuals worldwide and continue to decline despite conservation efforts (Pace et al., 2017). Though commercial whaling no longer poses a threat to right whales, there are other factors that have proven to be detrimental to their survival. In particular, ship strikes and entanglement in fishing rope are the main causes for continued population decline (Knowlton et al., 2012).
One may ask, how is all of this connected specifically to the Maine lobster industry? It has been determined that approximately 80% of right whales currently have scars along their bodies as a result of being entangled in fishing rope. More specifically, the rope that right whales are becoming entangled in is the vertical line used by lobstermen that connects the lobster trap lying on the seafloor to a buoy at the surface. Not only can this entanglement lead to the drowning of individuals, but also a decreased birth rate among females due to stress should they successfully free themselves (Knowlton et al., 2012).
In an attempt to decrease entanglement rates and bring the decline in right whale populations to a halt, the state of Maine has been in the process of creating and implementing new policies, many of which will have an impact on the lobster industry. Regulations that have been considered include weakened vertical lines, modified gear marking, a change in rope color, reduction in traps, or even the introduction of new ropeless technology.
What perceptions do lobstermen in Maine have regarding the conservation of right whales and the possible regulations that could be put into place? To address this question, I posted a Google Forms survey link on a local Maine fishermen’s Facebook page in late December 2018 that remained open until the end of February 2019. The five-minute survey was to be completed on a voluntary basis to gather a convenient sample from the 15,000 members on the group page, of which not all were lobstermen. There was a total of 39 participants. The survey asked about opinions regarding a series of possible regulations that could possibly impact the lobster industry, should they be implemented. Additionally, the survey provided space for lobstermen to explain how past regulations had impacted them personally, as well as space for recommendations they thought would help conserve right whale populations while simultaneously creating little negative impact on the lobster industry.

Small-scale fisheries are globally ubiquitous, employing more than 99% of the world’s fishers and providing over half of the world’s seafood. However, small-scale fisheries face many management challenges including declining catches, inadequate resources and infrastructure, and overcapacity. Baja California Sur, Mexico (BCS) is a region with diverse small-scale fisheries; these fisheries are intense, poorly regulated, and overlap with foraging hot spots of endangered sea turtles. In partnership with researchers, fishers, managers, and practitioners from Mexico and the United States, I documented bycatch rates of loggerhead turtles at BCS that represent the highest known megafauna bycatch rates worldwide. Concurrently, I conducted a literature review that determined gear modifications were generally more successful than other commonly used fisheries management strategies for mitigating bycatch of vulnerable megafauna including seabirds, marine mammals, and sea turtles. I then applied these results by partnering with researchers, local fishers, and Mexico’s federal fisheries science agency to develop and test two gear modifications (i.e. buoyless and illuminated nets) in operating net fisheries at BCS as potential solutions to reduce bycatch of endangered sea turtles, improve fisheries sustainability, and maintain fisher livelihoods. I found that buoyless nets significantly reduced mean turtle bycatch rates by 68% while maintaining target catch rates and composition. By contrast, illuminated nets did not significantly reduce turtle bycatch rates across day-night periods, although they reduced mean turtle bycatch rates by 50% at night. Illuminated nets, however, significantly reduced mean rates of total bycatch biomass by 34% across day-night periods while maintaining target fish catch and market value. I conclude with a policy analysis of the unilateral identification of Mexico by the U.S. State Department under section 610 of the Magnusson-Stevens Fishery Conservation and Management Act for failure to manage bycatch of loggerhead turtles at BCS. Taken together, the gear modifications developed and tested here represent promising bycatch mitigation solutions with strong potential for commercial adoption, but fleet-wide conversion to more selective and turtle-friendly gear (e.g. hook and line and/or traps) at BCS, coupled with coordinated international conservation action, is ultimately needed to eliminate sea turtle bycatch and further improve fisheries sustainability.
