Can Climate‐Induced Changes in Freshwater Game Fish Abundance Be Inferred From Digital Catch Log Data?

Fisheries Management and Ecology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 4, 2025

ABSTRACT The growing popularity of digital catch logs may present a low‐cost opportunity to monitor climate change effects on the distribution and relative abundance game fishes over large spatial scales. We analyzed data from popular fishing app identify spatiotemporal trends in freshwater fish catches throughout contiguous United States during 2015–2021. Warm‐water species became more common than cool‐water many locations. Increases tended occur northern range boundaries or non‐native ranges, declines at southern boundaries. Although log can be biased results reflect alternative phenomena operating interacting similarly scales (e.g., cultural eutrophication, changes popularity), remains viable explanation. Future research should further explore as potential tool for monitoring responses other stressors longer time frames multiple

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. Fostering better handling practices behaviors angling through education improve interactions between people while ensuring more successful releases ecological benefits across fisheries. acknowledge cultural norms values underpin ethical perspectives, vary among individuals, regions rural vs. urban), geopolitical jurisdictions, these can dictate angler behavior objectives as well how are perceived.

Freshwater megafauna shape ecosystems and facilitate restoration

Freshwater megafauna, such as sturgeons, giant catfishes, river dolphins, hippopotami, crocodylians, large turtles, and salamanders, have experienced severe population declines range contractions worldwide. Although there is an increasing number of studies investigating the causes megafauna losses in fresh waters, little attention has been paid to synthesising impacts on abiotic environment other organisms freshwater ecosystems, hence consequences losing these species. This limited understanding may impede development policies actions for their conservation restoration. In this review, we synthesise how shape ecological processes ecosystems discuss potential enhancing ecosystem Through activities movement, burrowing, dam nest building, a profound influence extent water bodies, flow dynamics, physical structure shorelines substrata, habitat heterogeneity.

Seasonal resilience of temperate estuarine fish in response to climate change

To date, the intricacies and efficacy of how periodic seasonal environmental fluctuations affect fish populations in biogeography context profound climate change remain to be elucidated. Collected monitoring data on resources temperate estuary provide an excellent opportunity assess effects functional assemblages under change. We first developed a framework for predicting habitat suitability different scenarios (SSP1-2.6 SSP5-8.5) 12 Yangtze by examining affinities estuarine fishes. then summarized multidimensional responses (HSRs) discussed possible drivers mechanisms underlying these changes. The results suggest that acidity may decline future as warms, endangering ecosystem many species depend on. Prospective have impact population HSRs through redistribution, area changes, centroid migration suitable habitats; nevertheless, affinity factors limited distinguishing patterns response spring. Fish (5 populations) (11 assemblages) exhibit robust adaptations or non-adaptations when seasons change, given their area. Furthermore, projections indicate majority centroids responses, migrating northeast spring southeast autumn. By decentralizing risk scales, resilience several (5/12) (11/16) is revealed time. Efforts mitigate risks safeguard should take forecasts indicative information into account.

Application of a trait‐based climate change vulnerability assessment to determine management priorities at protected area scale

Abstract Estimating and planning for the impacts of climate change on biodiversity protected areas is a major challenge conservation managers. When these are topographically heterogenous contain species' entire ranges, this exacerbated because coarse spatial scales Global Circulation Model projections provide limited information within‐park management. South Africa's Table Mountain National Park, home to three endemic amphibian species in just ~24,500 hectares, provides case study identifying needs under change. Selecting park's herpetofauna as pilot taxa, we identified life history demographic characteristics believed make more sensitive less able adapt We organized into assessment frameworks and, through combination literature review expert elicitation, reviewed used them assess vulnerability 18 41 reptile species. The highlighted that 73% 67% species, respectively, had at least one high‐sensitivity low‐adaptive capacity trait. Using ordinal additive scoring methods, most vulnerable highlight park containing their highest concentrations. These will be inform landscape‐scale management priorities use zones. current IUCN Red List assessments do not incorporate vulnerability. Considering some appear threatened by change, might underestimated. Identifying mechanisms underpinning can guide identification prioritization needs, while knowledge gaps monitoring research. While comprehensive adaptation Park requires additional other taxonomic groups, trait‐based example highlights viable tool assessing areas.

Overturning stereotypes: The fuzzy boundary between recreational and subsistence inland fisheries

Fish and Fisheries, Год журнала: 2022, Номер 23(6), С. 1282 - 1298

Опубликована: Июнь 15, 2022

Abstract Inland recreational fisheries provide numerous socio‐economic benefits to fishers, families and communities. Recreationally harvested fish are also frequently consumed may affordable sustainable but undervalued contributions human nutrition. Quantifying the degree which recreationally contribute food security subsistence is impeded by lack of data on harvest consumption difficulty in differentiating among fisheries. Recreational records tend be limited wealthy, food‐secure countries well‐monitored with clear regulations or permitting systems. These often neglect components food‐insecure fishers who potentially more likely have as a motivation. Here, we highlight ‘fuzzy boundary’ that can exist between inland argue unreported hidden contributor some populations. We draw local case studies from around world specific instances where species participating use these examples diversity ways nutrition, knowledge gaps understanding fishing for food, consequences not accounting them policy management. The aim this paper attention resource managers makers, create greater social awareness importance bring light contribution nutrition subsistence.
