Abstract Decision‐makers in inland fisheries management must balance ecologically and socially palatable objectives for ecosystem services within financial or physical constraints. Climate change has transformed the potential range of available. The Resist‐Accept‐Direct (RAD) framework offers a foundation responding to climate‐induced modification; however, trajectories current practices be understood improve future decisions. Using Wisconsin's diverse as case study, strategies recreational subsistence response climate were reviewed RAD framework. Current largely focus on resist actions, while may need shift toward accept direct actions. A participatory adaptive co‐production policies between state tribal agencies could prioritise lakes appropriate action, with goal providing landscape fishing opportunities. This knowledge represents process social learning requiring substantial investments funding time.

Abstract Lake ecosystems are shifting due to many drivers including climate change and landscape‐scale habitat disturbance, diminishing their potential support some fisheries. Walleye Sander vitreus (Mitchill) populations, which recreational tribal fisheries across North America, have declined in lakes. Climate change, harvest, invasive species concurrent increases warm‐water fishes (e.g. Centrarchidae) may contributed declines. To test the utility of an intensive management action resist walleye loss, experimental removal ~285,000 centrarchids from a 33‐ha lake over 4 years was conducted while monitoring fish community response. Centrarchid abundance yellow perch Perca flavescens increased, yet no evidence recruitment observed. These findings explore feasibility resistance as strategy supporting facing environmental provide platform for discussions move beyond strategies Resist‐Accept‐Direct (RAD) framework navigate ecosystem change.

Abstract Fisheries management is a complex task made even more challenging by rapid and unprecedented socioecological transformations associated with climate change. The Resist‐Accept‐Direct (RAD) framework can be useful tool to support fisheries in facing the high uncertainty variability aquatic ecosystem transformations. Here, RAD strategies are presented address ecological goals for ecosystems social fisheries. These mapped on controllability matrix which explores ability guide system's behaviour towards desired state based responsiveness societal receptivity Understanding improving of systems help managers maintain broadest suite available strategies.

Abstract In recent years considerable interest has been generated in a new approach known as resist – accept direct , or RAD, for managing ecosystems the face of climate change. Under strategic responses to change are described terms three broad categories: resisting transformation, accepting transformation and continuing manage best one can, directing transformed system toward novel ecological conditions. particular, potential integrating RAD adaptive management broadly considered, though absent decision‐making framework needed implementation. We propose hierarchical decision scheme that accounts strategy selection among options, well making within each option. use stochastic models uncertainties about ecosystem processes account dynamics climate‐transformed ecosystems, show how these features can be used inform strategies. Operationally, involves decisions at two levels: level choosing policy strategy, second deciding which greatest value. The structure here extends work adaptation, by including Markovian under change, strategy‐specific policies, value functions assessing selecting provide accounting responses, develop rules timing those decisions. Combining help organize thinking conservation focus attention on mechanisms believe presented facilitate efforts non‐stationary conditions we sure foreseeable future.

Walleye/ogaa ( Sander vitreus (Mitchill)) (hereafter, walleye; ogaa = Ojibwe translation) populations have historically supported important multi-use, harvest-oriented fisheries. Despite intensive management, walleye declined in the midwestern United States raising concerns about sustainability of species. Numerous factors been implicated population declines, including climate change, habitat loss, invasive species, species-interactions, production overharvest (i.e., harvest consistently exceeding annual production), and changing angler behaviors. These negatively influenced natural recruitment contributed to depensatory dynamics. I provide a review perspective suggesting that current trajectory is at or nearing an ecological tipping point. Although fish are often considered compensatory density-dependent), appear prone depensation positive density dependence). My suggest management for misaligned. A change towards resource focus using ecosystem-based fisheries recognition as social–ecological systems needed conservation. If ensues, persistence will likely be further threatened because many drivers outside managerial control, those commonly used within control seemingly ineffective sustaining rehabilitating naturally reproducing populations.

Abstract Ojibwe Tribes' approach to the natural world is guided by original treaties between beings (species and spirits) people who reside in lands now known as United States Canada. Relationships with these beings, such ogaa (walleye Sander vitreus ), are best characterised taking care of a relative/gift for next seven generations Ojibwe. Initial denial treaty rights state government has strongly influenced tribes' relationship their relatives over 100 years. Ogaa stocks reproduction have declined Minocqua Chain Lakes (Wisconsin, USA) last 20 Region‐wide declines been attributed many stressors overharvest state‐licensed anglers, invasive species climate change. Here, we retroactively applied resist–accept–direct (RAD) framework process used create an interjurisdictional rehabilitation plan Lakes. Specifically, cover following: progress date on plan; subsistence, cultural spiritual challenges associated resisting ecosystem change; unforeseen obstacles rehabilitation; re‐evaluation ogaa; unknowns; contingency plans from tribal perspective. Lastly, discuss how RAD could become more useful tribes region.

Walleye ( Sander vitreus) are an ecologically important species managed for recreational, tribal, and commercial harvest. prefer cool water low light conditions, therefore changing temperature clarity potentially impacts walleye habitat populations across the landscape. Using survey data collected from 1993 to 2018 312 lakes in Minnesota, we evaluated relationship between thermal-optical relative abundance of small (0–300 mm), medium (300–450 large (450 + mm) walleye. Thermal-optical was positively correlated with but not were more abundant larger, naturally reproducing opposed smaller, stocked lakes. changed 59% since 1980 (26% increasing 33% decreasing) appears be driven primarily by changes thus optical area.

Abstract Understanding and predicting recruitment, longstanding goals in fisheries science ecology, are complicated by variation the importance of environmental drivers coupled with dynamic nature individual ecosystems. Developing an understanding recruitment from well-monitored stocks offers opportunity to overcome these complexities. We used a systematic literature review, survey, workshop attended professionals expertise Walleye Sander vitreus identify common additional sources (i.e., context dependencies) among populations. The drivers, as well direction their influence, differed function geographic region, lake surface area, life stage. suggested abiotic conditions (e.g., temperature) during first year were influential determining recruitment. Professional opinion noted biotic factors, prey availability predation risk having most consistent relationships synthesized this information propose conceptual model that illustrates suite characteristics shape over large spatial temporal scales. Our findings emphasize first-year growth system-specific contextual which can alter relative

Managing fisheries in a changing socio-ecological environment may require holistic approaches for identifying and adapting to novel ecosystem dynamics. Using 32 years of Ceded Territory Wisconsin (CTWI) walleye ( Sander vitreus) data, we estimated production P), biomass B), turnover P/B), yield Y), over Y/P) tested hyperstability yield. Most CTWI populations showed low P B, Y/P < 1 . Yet, overharvest > 1) was prevalent among recruitment-based management (natural recruitment (NR), sustained only by stocking, combination). Production, P/B have declined NR populations, while Y remained constant. Walleye hyperstable along gradient all fishery types (i.e., angling only, angling/tribal harvest combined). Diminishing productivity be jointly contributing observed declines. We classified lakes into groups low, moderate, or high vulnerability based on dynamics identify that benefit from declines maintain increase the adaptive capacity walleye.
