Individual outcomes matter in the context of responsible and sustainable catch-and-release practices in recreational fisheries and their management

Fisheries, Год журнала: 2025, Номер unknown

Abstract Recreational anglers often engage in catch-and-release (C&R) whereby some of their catch is returned to the water (either comply with harvest regulations or voluntarily) assumption that fish will survive and experience negligible impacts. Despite C&R usually harmless and, thus, helps reduce overall fishing mortality, a large evidence base shows proportion released not survive. Even if event lethal, each individual sublethal impact (e.g., injury stress). There debate within recreational fisheries science management community regarding extent which impacts even mortality matter, given efforts focus on whether excessive affects population size quality angling. Here, we embrace perspective individual-level outcomes matter context responsible sustainable management. We outline 10 reasons why there need account for generate resilient under changing climate face other ongoing, increasing, future threats stressors.

Managing Freshwater Fish in a Changing Climate: Resist, Accept, or Direct

Fisheries, Год журнала: 2022, Номер 47(6), С. 245 - 255

Опубликована: Янв. 10, 2022

Abstract Climate change is altering the distribution, phenology (e.g., timing of spawning), and community dynamics freshwater fishes. Managers have three options for responding to these changes: “Resist” maintain or restore historic abiotic biological conditions; “Accept” manage within new “Direct” produce conditions considered desirable by humans. I discuss how inland fisheries management approaches stocking, regulations, habitat improvement, manipulations can be applied Resist-Accept-Direct (RAD) framework. also ways choose among ecological tipping points used determine when Resist no longer a feasible option managers must shift Accept Direct options.

Reviving the unique potential of recreational fishers as environmental stewards of aquatic ecosystems

Fish and Fisheries, Год журнала: 2022, Номер 24(2), С. 339 - 351

Abstract Recreational anglers have been key players in aquatic conservation, but this role is increasingly obscured. Other environmental sectors are now more visible stakeholders engaged with biodiversity. fishing has relevant and moral implications, these can be resolved via improved governance management. More difficult replacing the stewardship capacity provided by anglers. When analysed against a novel framework based on place identity, care, knowledge agency, we find that marginalizing could diminish biodiversity conservation. This outcome likely because excellence recreational involves habituation of skills ethical imperatives associated sustainable responsible use fish populations. These dimensions probably not so pertinent correspondingly less developed other nature stakeholders. Importantly, catching killing wild animals catapults into food web ecological conscience most outdoor activities cannot generate. As result, often engenders feelings care responsibility for systems support personal well‐being, bridging value‐action gap through development local assessment, management evaluative competencies agency. Transdisciplinary cooperation scientists, managers policymakers unleash potential engage their common good.

Global assessment of marine and freshwater recreational fish reveals mismatch in climate change vulnerability and conservation effort

Global Change Biology, Год журнала: 2021, Номер 27(19), С. 4799 - 4824

Опубликована: Июль 21, 2021

Abstract Recreational fisheries contribute substantially to the sociocultural and economic well‐being of coastal riparian regions worldwide, but climate change threatens their sustainability. Fishery managers require information on how will impact key recreational species; however, absence a global assessment hinders both directed widespread conservation efforts. In this study, we present first vulnerability recreationally targeted fish species from marine freshwater environments (including diadromous fishes). We use projections data species’ physiological ecological traits quantify map analyze these patterns alongside indices socioeconomic value effort determine where efforts are sufficient they might fall short. found that over 20% fishes vulnerable under high emission scenario. Overall, had highest number species, concentrated in with sensitive habitat types (e.g., coral reefs). However, higher proportions at risk change, concentrations northern Europe, Australia, southern Africa. Mismatches were within all life‐history groups. A pattern was current focused primarily rather than predicted be proportionately more vulnerable. While several notably lacking protection Caribbean Sea, Banda Sea), only 19% without effort. By contrast, 72% 33% no measures place, despite cultural value. The spatial taxonomic analyses presented here provide guidance for future management as progresses.

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.

Bright spots for inland fish and fisheries to guide future hydropower development

Hydropower production is one of the greatest threats to fluvial ecosystems and freshwater biodiversity. Now that we have entered Anthropocene, there an opportunity reflect on what might constitute a 'sustainable' Anthropocene in context hydropower riverine fish populations. Considering elements existing practices promote favorable social-ecological outcomes (i.e., 'bright spots') timely given are plans expand capacity previously undammed rivers, intensify dam development some world's largest river systems, re-license facilities. We approach this from pragmatic perspective: for foreseeable future, will likely remain important source renewable electricity.

Abstract Large‐scale modelling and prediction provide insight into general influences of climate change on inland recreational fisheries; however, small‐scale dynamics local expertise will be key in developing explicit goals for managing fisheries as the changes. The resist‐accept‐direct (RAD) framework encompasses entire decision space managers consider when addressing their system, but to decide whether resist, accept or direct, need tools understand how specific waterbodies influenced by change. Here, a decision‐support tool was developed applied walleye fishery Wisconsin, USA an example link RAD real‐world management large fishery. broadscale results described here, indicating widespread shift away from resist strategies mid‐century, can used inform decisions about accept, direct populations.
