Abstract Factors including human dispersal, climate change and varied environmental stressors are altering fish species distributions. Range expansions producing new records of freshwater which were rare or previously absent from regional jurisdictions (states, provinces territories). Simultaneously, facing declines local extirpations in some areas their distribution. The Resist‐Accept‐Direct (RAD) framework can provide guiding principles for how declining, newly arrived, range expanding fishes should be managed range‐wide trends considered management conservation decisions. We examine the an example decision tree is applied to examples ranging resisting establishment potentially harmful non‐native fishes, accepting providing refuge those threatened other parts ranges, directing migration improve ecosystem services. Applying this may coordination between agencies aiming resilience ecosystems.

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

ABSTRACT Objective Brown Trout Salmo trutta are commonly stocked in high-order rivers to create recreational fisheries and supplement naturalized populations. At temperate latitudes New England, most larger present climate-driven physiological challenges for Trout. Understanding the movement survival of poststocking these systems can inform more effective stocking practices that maintain angling opportunities.

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.

Abstract Climate change and a host of other human stressors on aquatic systems in the American Southwest are rapidly exceeding our ability to conserve native fish diversity. The most severe megadrought over millennium has compromised current management plans by exacerbating impacts altered hydrology, poor water quality, invasive species, habitat fragmentation. Drought legacies particular concern, existing conservation actions may not be sufficient maintain resilient populations, particularly if this drought persists. We draw examples from literature empirical research support contention that more resources novel approaches prioritizing environmental flows, improving ecological connectivity preventing controlling establishing refuge populations necessary stave off extinctions. Moreover, shifts socio-political attitudes better recognize concerns must integrated into resource policy achieve goals.

AbstractLargemouth Bass (Micropterus salmoides, LMB) and Smallmouth dolomieu, SMB) are among the most highly invasive species across globe, but simultaneously sought-after game fish. To explain these disparate views, data on status angling participation of two were compiled at country level. Largemouth found established in 62 countries five continents, whereas SMB only nine same continents. Invasive risk assessments between species, with more for (N = 29) than LMB 27). In every instance save one (Finland), considered "invasive" compared to LMB, which 74% assessments. Twenty-eight non-native black bass have groups that participate high-profile fishing tournament such Black World Championship, BASS (Bass Anglers Sportsmans Society) Nation, Major League Fishing. Most tournaments occur populations populations, suggesting a greater economic importance fishing.

I reflect upon how successful the implementation of Canadian Species at Risk Act (SARA), enacted in 2022, has been meeting its intended purposes protecting and recovering at-risk species through five-step SARA process, particularly as it relates to aquatic risk. For each one steps, identify shortcomings provide recommendations overcome those challenges. The overall process fallen far short incorporating Indigenous knowledge outlined Act, dealt poorly with climate change, underestimated need for Western science step process. Addressing these challenges would require large increases funding, current funding is woefully inadequate undertake legislated requirements SARA, let alone aspirational goals actually species. Despite challenges, we have better than alternative no all that many benefitted.
