We review fleet dynamics and fishermen behavior from an economic sociological basis in developing fisheries, mature fisheries near full exploitation, senescent that are overexploited overcapitalized. In all cases, fishing fleets behave rationally within the imposed regulatory structures. Successful, generalist who take risks often pioneer fisheries. At this stage, regulations subsidies tend to encourage excessive entry investments, creating potential for serial depletion. restrict season...
Climate change is impacting fisheries worldwide with uncertain outcomes for food and nutritional security. Using management strategy evaluations key US in the eastern Bering Sea we find that Ecosystem Based Fisheries Management (EBFM) measures forestall future declines under climate over non-EBFM approaches. Yet, benefits are species-specific decrease markedly after 2050. Under high-baseline carbon emission scenarios (RCP 8.5), end-of-century (2075-2100) pollock Pacific cod collapse >70%...
Recent years have seen a rapid expansion in the ability of earth system models to describe and predict physical state ocean. Skilful forecasts ranging from seasonal (3 months) decadal (5-10 years) time scales are now reality. With advance these ocean physics, first generation marine ecological has started emerge. Such potentially great value management living resources for all those who dependent on both nutrition their livelihood; however, this is still field its infancy. We review art...
Spatial closures like marine protected areas (MPAs) are prominent tools for ecosystem-based management in fisheries. However, the adaptive behavior of fishermen, apex predator ecosystem, to MPAs may upset balance fishing impacts across species. While (EBM) emphasizes protection all species environment, weakest stock often dominates attention. We use data before and after implementation large spatial a North Pacific trawl fishery show how designed red king crab spurred dramatic increases...
It is increasingly evident that climate change having significant impacts on marine ecosystems and dependent fisheries. Yet, translating science into management actions policies an ongoing challenge. In particular, four aspects have confounded implementation of climate-resilient management: (i) regional tools may not be well-suited for managing the same systems under change, (ii) individual research studies are often implicitly focussed spatio-temporal scales rarely aligned, (iii) approaches...
Abstract Commercial tunas and billfishes (swordfish, marlins sailfish) provide considerable catches income in both developed developing countries. These stocks vary status from lightly exploited to rebuilding severely depleted. Previous studies suggested that this variability could result differences life‐history characteristics economic incentives, but exploitation histories management measures also have a strong effect on current stock status. Although the (biomass fishing mortality rate)...
Significance Individuals who rely on natural resources for their livelihoods, such as fishers, farmers, and forestry workers, face high levels of income variability. For catching multiple species has been shown to reduce revenue variability at large scales (vessels communities), but the individual-level consequences maintaining catch diversity are unknown. Our work demonstrates that individuals in fisheries targeting a participate buffer compared with less diverse individuals. However,...
The Alaska CLimate Integrated Modeling (ACLIM) project represents a comprehensive, multi-year, interdisciplinary effort to characterize and climate-driven changes the Eastern Bering Sea ecosystem, from physics fishing communities. Results ACLIM are being used understand how different regional fisheries management approaches can help promote adaptation sustain fish shellfish populations inform managers fishery dependent communities of risks associated with future climate scenarios. relies on...
Abstract Efforts to manage living marine resources (LMRs) under climate change need projections of future ocean conditions, yet most global models (GCMs) poorly represent critical coastal habitats. GCM utility for LMR applications will increase with higher spatial resolution but obstacles including computational and data storage costs, obstinate regional biases, formulations prioritizing robustness over skill persist. Downscaling can help address limitations, significant improvements are...

Characterization of uncertainty (variance) in ecosystem projections under climate change is still rare despite its importance for informing decision-making and prioritizing research. We developed an ensemble modeling framework to evaluate the relative different sources food web Eastern Bering Sea (EBS). Specifically, dynamically downscaled from Earth System Models (ESM) greenhouse gas emission scenarios (GHG) were used force a multispecies size spectrum model (MSSM) EBS web. In addition ESM...
Killer whale (Orcinus orca) depredation (whales stealing or damaging fish caught on fishing gear) adversely impacts demersal longline fisheries for sablefish (Anoplopoma fimbria), Pacific halibut (Hippoglossus stenolepis) and Greenland turbot (Reinhardtius hippoglossoides) in the Bering Sea, Aleutian Islands Western Gulf of Alaska. These interactions increase direct costs opportunity associated with catching reduce profitability western This study synthesizes National Marine Fisheries...
Abstract Heterogeneity in human responses and decision‐making can contribute to the resilience of social–ecological systems face environmental, political economic pressures. In fishery worldwide, ability harvesters maintain a diverse portfolio fishing strategies is important for building adaptive capacity. We used case‐study approach examine complexity factors that inhibit or promote diversification fisheries Alaska, one major regions world. Through combination harvest records literature...
Motivated by a need for climate-informed living marine resource management, increased emphasis has been placed on regional end-to-end modeling frameworks designed to project climate impacts ecosystems and evaluate the efficacy of potential management strategies under changing conditions. The 'Future Seas' was initiated with focus three fisheries (Pacific sardine, swordfish, albacore tuna) in California Current System (CCS). This work leverages suite climate, ocean, ecosystem, economic models...
Abstract Haynie, A. C., and Pfeiffer, L. 2012. Why economics matters for understanding the effects of climate change on fisheries. – ICES Journal Marine Science, 69: . Research attempting to predict effect fisheries often neglects consider how harvesters respond changing economic, institutional, environmental conditions, which leads overly simplistic prediction “fisheries follow fish”. However, can be complex because they arise through physical, biological, economic mechanisms that interact...
Time spent fishing is the effort metric often studied in fisheries but it may under-represent actually expended by fishers. Entire trips, from time vessels leave port until they return, prove more useful for examining trends fleet dynamics, fisher behavior, and costs. However, such trip information difficult to resolve. We identified ~30,000 trips made that targeted walleye pollock (Gadus chalcogrammus) Eastern Bering Sea 2008-2014 using vessel monitoring system (VMS) landings data. compared...
Recent observations of record low winter sea-ice coverage and warming water temperatures in the eastern Bering Sea have signaled potential impacts climate change on this ecosystem, which implications for commercial fisheries production. We investigate forecasted food web through end century under medium- high-emissions scenarios combination with a selection management strategies by conducting simulations using dynamic model. The outputs from three global earth system models run two...
Abstract While the science supporting fisheries management has generally been dominated by natural sciences, there a growing recognition that managing essentially means economic systems. Indeed, over past seven decades, ideas and insights have increasingly come to play role in policy. As an illustration of this, International Council for Exploration Sea (ICES) actively seeking expand scope its scientific expertise beyond sciences [another inter-governmental marine organization which done...
