Recent warming in the Northeast United States continental shelf ecosystem has raised several concerns about the impacts on the ecosystem and commercial fisheries. In 2014, researchers from the Commercial Fisheries Research Foundation and Woods Hole Oceanographic Institution founded the Shelf Research Fleet to involve fishers in monitoring the rapidly changing ocean environment and encourage sharing of ecological knowledge. The Shelf Research Fleet is a transdisciplinary, cooperative program that trains commercial fishers to collect oceanographic information by deploying conductivity, temperature, and depth (CTD) instruments while commercially fishing. A total of 806 CTD profiles have been collected by the Shelf Research Fleet through December 2022. Participating vessels can view the conductivity and temperature water column profiles they collect in real-time. These profiles help inform their fishing practices and give insights when unexpected species appear in their gear or if their catch composition changes from previous years. The data collected by the Shelf Research Fleet are shared with and processed by researchers from numerous partnering institutions. The Shelf Research Fleet data have been used by researchers to better understand oceanographic phenomena including marine heatwaves, shelf-break exchange processes, warm core rings, and salinity maximum intrusions onto the continental shelf. The scope of the Shelf Research Fleet has grown over time to include efforts to more directly link oceanographic results with biological observations to better understand how changing ocean conditions are affecting commercially important species. This article describes the approach, successes, challenges, and future directions of the Shelf Research Fleet and aims to outline a framework for a cost-effective research program that engages fishers in the collection of oceanographic data, strengthening partnerships between fishing industry members and the scientific community.

Charting a new course: ungraying the fleet and comprehensively supporting fishing livelihoods and communities
This article provides perspectives on the graying of the fleet and research efforts to understand it in Alaska fisheries, discusses recent abrupt multifaceted challenges faced by Alaskan fishermen, and compares divergent public perceptions and support programs for farmers and fishermen in the United States. Equity concerns have seen a resurgence in academic and policy realms and the graying of the fleet is now a common example of distributional inequity, yet despite in-depth research attention on the issue, few substantive programmatic modifications have been made to address it in Alaska. Aging trends in United States fisheries have typically been framed as one of changing aspirational preferences. Research suggests coastal youth do desire and highly value fishing careers, but structural and financial barriers limit opportunities for new generations. The precarity of the fishing industry was highlighted in 2023 with sudden global seafood market instability, rising interest rates and operating costs, destabilized geopolitical tensions, and hastening climate change impacts. This recent industry turmoil disproportionately impacts those on the margins and adds an additional layer of complexity to addressing graying of the fleet trends. Unlike in fisheries, there are numerous federal programs to support young farmers and the agricultural industry. This paper calls for proactive and comprehensive measures to stabilize and support fishing communities and the viability of next generation pathways amidst recent fishing industry market turmoil and longer term inequities in fishery governance.

Subsidies are widely criticized in fisheries management for promoting global fishing capacity growth and overharvesting. Scientists worldwide have thus called for a ban on “harmful” subsidies that artificially increase fishing profits, resulting in the recent agreement among members of the World Trade Organization to eliminate such subsidies. The argument for banning harmful subsidies relies on the assumption that fishing will be unprofitable after eliminating subsidies, incentivizing some fishermen to exit and others to refrain from entering. These arguments follow from open-access governance regimes where entry has driven profits to zero. Yet many modern-day fisheries are conducted under limited-access regimes that limit capacity and maintain economic profits, even without subsidies. In these settings, subsidy removal will reduce profits but perhaps without any discernable effect on capacity. Importantly, until now, there have been no empirical studies of subsidy reductions to inform us about their likely quantitative impacts. In this paper, we evaluate a policy reform that reduced fisheries subsidies in China. We find that China’s subsidy reductions accelerated the rate at which fishermen retired their vessels, resulting in reduced fleet capacity, particularly among older and smaller vessels. Notably, the reduction of harmful subsidies was only partly responsible for reducing fleet capacity; an increase in vessel retirement subsidies was also a necessary driver of capacity reduction. Our study demonstrates that the efficacy of removing harmful subsidies depends on the policy environment in which removals occur.more » « less

Abstract A network of marine reserves can enhance yield in depleted fisheries by protecting populations, particularly large, old spawners that supply larvae for interspersed fishing grounds. The ability of marine reserves to enhance sustainable fisheries is much less evident. We report empirical evidence of a marine reserve network improving yield regionally for a sustainable spiny lobster fishery, apparently through the spillover of adult lobsters and behavioral adaptation by the fishing fleet. Results of a Before-After, Control-Impact analysis found catch, effort, and Catch-Per-Unit Effort increased after the establishment of marine reserves in the northern region of the fishery where fishers responded by fishing intensively at reserve borders, but declined in the southern region where they vacated once productive fishing grounds. The adaptation of the northern region of the fishery may have been aided by a history of collaboration between fishers, scientists, and managers, highlighting the value of collaborative research and education programs for preparing fisheries to operate productively within a seascape that includes a large marine reserve network.more » « less

Abstract The 2010Deepwater Horizon(DwH) disaster challenged the integrity of the Gulf of Mexico (GOM) large‐marine ecosystem at unprecedented scales, prompting concerns of devastating injury for GOM fisheries in the post‐spill decade. Following the catastrophe, projected economic losses for regional commercial, recreational, and mariculture sectors for the decade after oiling were US$3.7–8.7 billion overall, owing to the vulnerability of economically prized, primarily nearshore taxa that support fishing communities. State and federal fisheries data during 2000–2017 indicated that GOM fishery sectors appeared to serve as remarkable anchors of resilience following the largest accidental marine oil spill in human history. Evidence of post‐disaster impacts on fisheries economies was negligible. Rather, GOM commercial sales during 2010–2017 were US$0.8–1.5 billion above forecasts derived using pre‐spill (2000–2009) trajectories, while pre‐ and post‐spill recreational fishery trends did not differ appreciably. No post‐spill shifts in target species or effort distribution across states were apparent to explain these findings. Unraveling the mechanisms for this unforeseen stability represents an important avenue for understanding the vulnerability or resilience of human–natural systems to future disturbances. FollowingDwH, the causes for fishery responses are likely multifaceted and complex (including exogenous economic forces that typically affect fisheries‐dependent data), but appear partially explained by the relative ecological stability of coastal fishery assemblages despite widespread oiling, which has been corroborated by multiple fishery‐independent surveys across the northern GOM. Additionally, we hypothesize that damage payments to fishermen led to acquisition or retooling of commercial fisheries infrastructure, and subsequent rises in harvest effort. Combined, these social–ecological dynamics likely aided recovery of stressed coastal GOM communities in the years afterDwH, although increased fishing pressure in the post‐spill era may have consequences for future GOM ecosystem structure, function, and resilience.more » « less

Abstract For most of the past few decades, landings in the American lobster (Homarus americanus) fishery in Maine have been increasing, but a recent downturn in catch suggests the fishery may be at an inflection point. Drawing on multiple datasets associated with the fishery, we use this period of transition to review fleet dynamics in the fishery by analyzing how fishing effort has changed through time (2008–2022). When possible, age, gender, geography, and scale of fishing operation are considered to delimit intra-fleet differences. The results of this review reveal large-scale changes in intra-fleet dynamics that help to explain how there has been the appearance of fleet-wide stability for most of the 15-year study period despite mounting socioeconomic and environmental stressors. Changes in intra-fleet dynamics are most evident across geography and scale of fishing operation. In addition, this study finds that prior research has overestimated a key metric of fishing effort in the Maine lobster fishery by an order of magnitude. This latter insight bears significance because the lobster industry is under mounting pressure to reduce risk of gear interactions with large marine mammals, and future management decisions will likely hinge on estimates about fishing effort and the probability of marine mammal interactions. Continued efforts to understand fishing fleet dynamics and how they differ among segments of the fishery are vital to making well-informed policy decisions in the face of change, including the iconic Maine lobster fishery.more » « less
