Abstract (from Fisheries): Inland recreational fishing, defined as primarily leisure-driven fishing in freshwaters, is a popular pastime in the USA. State natural resource agencies endeavor to provide high-quality and sustainable fishing opportunities for anglers. Managers often use creel and other angler survey data to inform state- and waterbody-level management efforts. Despite the broad implementation of angler surveys and their importance to fisheries management at state scales, regional and national coordination among these activities is minimal, limiting data applicability for larger-scale management practices and research. Here, we introduce the U.S. Inland Creel and Angler Survey Catalog (CreelCat), a first-of-its-kind,...

Abstract (from Fisheries Management and Ecology): 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 ecosystem services available. The Resist-Accept-Direct (RAD) framework offers a foundation for responding to climate-induced ecosystem modification; however, ecosystem trajectories and current practices must be understood to improve future decisions. Using Wisconsin's diverse inland fisheries as a case study, management strategies for recreational and subsistence fisheries in response to climate change were reviewed within the RAD framework....

Abstract (from Fisheries Management and Ecology): Lake ecosystems are shifting due to many drivers including climate change and landscape-scale habitat disturbance, diminishing their potential to support some fisheries. Walleye Sander vitreus (Mitchill) populations, which support recreational and tribal fisheries across North America, have declined in some lakes. Climate change, harvest, invasive species and concurrent increases in warm-water fishes (e.g. Centrarchidae) may have contributed to declines. To test the utility of an intensive management action to resist walleye loss, an experimental removal of ~285,000 centrarchids from a 33-ha lake over 4 years was conducted while monitoring the fish community response....

Abstract (from Fish and Fisheries): Inland recreational fisheries provide numerous socio-economic benefits to fishers, families and communities. Recreationally harvested fish are also frequently consumed and may provide affordable and sustainable but undervalued contributions to human nutrition. Quantifying the degree to which recreationally harvested fish contribute to food security and subsistence is impeded by lack of data on harvest and consumption and by the difficulty in differentiating among recreational and subsistence fisheries. Recreational harvest records tend to be limited to wealthy, food-secure countries and well-monitored fisheries with clear regulations or permitting systems. These records often...

Abstract (from Scientifc Data): Inland recreational fisheries, found in lakes, rivers, and other landlocked waters, are important to livelihoods, nutrition, leisure, and other societal ecosystem services worldwide. Although recreationally-caught fish are frequently harvested and consumed by fishers, their contribution to food and nutrition has not been adequately quantified due to lack of data, poor monitoring, and under-reporting, especially in developing countries. Beyond limited global harvest estimates, few have explored species-specific harvest patterns, although this variability has implications for fisheries management and food security. Given the continued growth of the recreational fishery sector, understanding...

Climate change impacts on large river basins, such as the Mekong River Basin (MRB), are complex due to shared governance and interconnected socioeconomic areas, making them highly vulnerable to change. The MRB, spanning six countries including Thailand, is crucial for the food and economic security of > 60 million people. However, in 2021, Thailand was ranked as the 9th highest risk country affected by climate change. To integrate climate adaptation in Thailand's MRB, we examined the effects of climate change on rapidly developing farmer and fisher communities in northeastern Thailand and explored feasible adaptation options. Using an interdisciplinary approach that included literature review, participatory action...

Abstract Climate change effects on large river basins, such as the Mekong River, are dramatic and unique given shared governance and watershed scale. In large rivers, socioeconomic sectors including agriculture, fisheries, transportation, human health, biodiversity, water supply, and livelihoods are interconnected and highly vulnerable to global change. The Mekong River is a transboundary river spanning six countries and is critical for food and economic security of >60 million people. But the Mekong River Basin has undergone extensive environmental changes due to agricultural expansion, deforestation, dam construction, urbanization, and population growth, and faces substantial confounding effects from climate change....
In response to concerns from Tribal leadership in the Midwest region, a Midwest Climate Adaptation Science Center (MWCASC) and Great Lakes Indian Fish and Wildlife Commission (GLIFWC) team explored how climate change may affect name (also known as lake sturgeon). This project investigated potential impacts and what can be done to help name adapt to a changing climate.

These data are nutrition, economic value, and climate vulnerability of inland recreational consumption by country. The dietary contribution is measured as calcium, omega-3 long-chain polyunsaturated fatty acids docosahexaenoic acid and eicosapentaenoic acid (hereafter referred as DHA+EPA), iron, protein, vitamin B12, and zinc supply. The economic contribution is measured as total consumptive use value [TCUV]). The climate vulnerability follows Nyboer et al. 2021, comparing four climate change scenarios.
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 of Wisconsin (CTWI) walleye (Sander vitreus) data, we estimated production (P), biomass (B), biomass turnover (P/B), yield (Y), and yield over production (Y/P) and tested for hyperstability in walleye yield. Most CTWI walleye populations showed low P, and B, and Y/P < 1. Yet, production overharvest (Y/P > 1) was prevalent among Wisconsin walleye recruitment-based management approaches (natural recruitment [NR], sustained only by stocking, combination). Production, B, and P/B have declined in NR populations, while Y and Y/P have remained...

Acipenser fulvescens (Rafinesque, 1817; lake sturgeon) are the only sturgeon species native to the Great Lakes region and are threatened across most of their range. They are historically vulnerable because of overfishing and habitat fragmentation with the potential for climate change acting as an increasing stressor in the future. Lake sturgeon span multiple habitats during their long lifespans, including high gradient streams, nearshore areas, and deep rivers and lakes. Climate change is projected to strongly affect the suitability of these habitats through increasing precipitation and temperatures and decreasing ice cover and snowmelt. Changes in flow timing and amount can affect movement to spawning and nursery...

Inland lake ecosystems are transforming due to unprecedented effects of climate changes and disturbance along riparian habitat, diminishing their potential to support fisheries. Walleye Sander vitreus, the most sought-after game fish in north-central North America supporting robust recreational and tribal fisheries, have declined. Climate change, harvest, invasive species, and concurrent increases in warm-water species (e.g., Centrarchidae) are implicated in declines. The Resist-Accept-Direct (RAD) framework provides a structure to reconcile managing ecosystem transformations. To examine the utility of intensive resist actions, we conducted an experimental removal of centrarchids in a north temperate lake. We removed...
(Abstract from Fisheries Management and Ecology): Recreational fisheries represent a socially, ecologically, and economically significant component of global fisheries. The U.S. Inland Creel and Angler Survey Catalog (CreelCat) database includes inland recreational fisheries survey data across the United States to facilitate large-scale analyses. However, because survey methods differ, a statistical method capable of integrating these surveys is necessary to assess patterns and relationships across regions. Here, we developed a hierarchical generalized linear mixed modeling approach to estimate the relationship between daily recreational fisheries catch and effort based on waterbody, socio-economic, and ecological...

Background Large-river decision-makers are charged with maintaining diverse ecosystem services through unprecedented social-ecological transformations as climate change and other global stressors intensify. The interconnected, dendritic habitats of rivers, which often demarcate jurisdictional boundaries, generate complex management challenges. Here, we explore how the Resist–Accept–Direct (RAD) framework may enhance large-river management by promoting coordinated and deliberate responses to social-ecological trajectories of change. The RAD framework identifies the full decision space of potential management approaches, wherein managers may resist change to maintain historical conditions, accept change toward different...

Habitat loss, pollution, species introductions, and overfishing have been impacting inland fisheries for decades. Climate change threatens to compound the factors that lead to fisheries decline. Walleye, an ecologically, economically and culturally important cool-water sportfish, have been declining in the Upper Great Lakes Region since the early 2000s. Yet while many inland walleye populations have declined, others have thrived, and some even appear to respond positively to warming temperatures in certain contexts (e.g. Honsey et al 2020). Rather than focusing on understanding walleye population declines, this project’s approach is to probe the factors that underlie successful, thriving fisheries. Focusing on ‘bright...
The United States Inland Creel and Angler Survey Catalog (CreelCat) contains a national compilation of angler and creel survey data collected by natural resource management agencies across the United States (including Washington, D.C. and Puerto Rico). These surveys are used to help inform the management of recreational fisheries, by collecting information about anglers including what they are catching and harvesting, the amount of effort they expend, their angling preferences, and demographic information. As of May 1, 2023, CreelCat houses over 14,729 surveys from 33 states, Puerto Rico, and Washington, D.C., comprising 235 data fields across 8 tables. These tables contain 235,015 records of fish catch and harvest...

Global change, including large scale changes in climate, land use, hydrology, and biogeochemistry, creates unprecedented pressure on inland recreational fisheries. Local fishery managers have little influence on these large-scale changes, but they can manipulate factors such as harvest, food web structure, and some features of habitat. The Safe Operating Space (SOS) concept establishes a framework for analyzing a fishery in the context of both large-scale and local factors. Adaptation is the manipulation of local factors (such as harvest, food web structure, or habitat) to maintain the SOS of a fishery as the climate changes. At the scale of many lakes on a landscape, the SOS can be used to identify lakes that are...
