Hydropower's role in the U.S. electrical grid is expected to evolve in response to increased wind and solar generation as hydropower will be called upon to quickly ramp up and down in response to changes in wind and solar generation. For this reason, hydropower is expected to have increased value as fossil generation is phased out, even as rapid flow fluctuations linked with hydropower flexibility may strand fish, alter habitat, and create unsafe recreational conditions. We face a new challenge in facilitating the renewable energy transition—designing environmental flow requirements that protect against the impacts of flow fluctuations while allowing adequate hydropower flexibility to support a stable grid. In this paper, we discuss hydropower environmental flow requirements, operational flexibility, and electrical grid stability, their potential interactions, and opportunities to align environmental and power system needs to support healthy ecosystems, multiple water uses, and decarbonization of the electric grid.</p>","PeriodicalId":12389,"journal":{"name":"Fisheries","volume":"49 11","pages":"524-535"},"PeriodicalIF":2.4,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fsh.11168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Israel","doi":"10.1002/fsh.11174","DOIUrl":"https://doi.org/10.1002/fsh.11174","url":null,"abstract":"<p>Trade-offs among objectives in natural resource management can be exacerbated in altered ecosystems and when there is uncertainty in predicted management outcomes. Multi-criteria decision analysis and value of information (VOI) are underutilized decision tools that can assist fisheries managers in handling trade-offs and evaluating the importance of uncertainty. We demonstrate the use of these tools using a case study in the Sacramento River, California, USA, where two imperiled species with different temperature requirements, winter-run Chinook Salmon <i>Oncorhynchus tshawytscha</i> and Green Sturgeon <i>Acipenser medirostris</i>, spawn and rear in the artificially cold Shasta Dam tailwater. A temperature-control device installed on Shasta Dam maintains cool water for Chinook Salmon; however, uncertainties exist related to the effects of temperatures on the spawning and rearing of both species. We consider four alternative hypotheses in models of early life-stage dynamics to evaluate the effects of alternative temperature management strategies on Chinook Salmon and Green Sturgeon management objectives. We used VOI to quantify the increase in management performance that can be expected by resolving hypothesis-based uncertainties as a function of the weight assigned to species-specific objectives. We found the decision was hindered by uncertainty; the best performing alternative depends on which hypothesis is true, with warmer or cooler alternative management strategies recommended when weights favor Green Sturgeon or Chinook Salmon objectives, respectively. The value of reducing uncertainty was highest when Green Sturgeon was slightly favored, highlighting the interaction between scientific uncertainty and decision makers' values. Our demonstration features multi-criteria decision analysis and VOI as transparent, deliberative tools that can assist fisheries managers in confronting value conflicts, prioritizing resolution of uncertainty, and optimally managing aquatic ecosystems.</p>","PeriodicalId":12389,"journal":{"name":"Fisheries","volume":"49 11","pages":"508-523"},"PeriodicalIF":2.4,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fsh.11174","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fishing technologies, such as sonar, are believed to enable anglers to be more efficient and effective in their angling. There are concerns from anglers and managers of increased catch by technology users. We assessed the relationships between technology use—defined as the use of imaging technology such as sonar and underwater cameras—and catch, angler expectations of catch, and trip satisfaction using a dual intercept creel survey. Angling technologies were used by 80% and 79% of intercepted boat and ice anglers, respectively, but only 3.9% of shore anglers. Fishing technologies increased expected catch for game fish anglers, but not panfish anglers, and had no effect on actual catch for either group. Most anglers caught fewer fish than expected, and technology did not improve their ability to meet expectations. Technology use was associated with decreased overall satisfaction among panfish and game fish anglers. These results suggest that concerns about fishing technology increasing catch may not be warranted. Rather, technology use may affect angler expectations and negatively impact angler satisfaction, potentially influencing angler behavior.</p>","PeriodicalId":12389,"journal":{"name":"Fisheries","volume":"49 10","pages":"463-474"},"PeriodicalIF":2.4,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fsh.11157","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although stakeholder engagement is increasing, the extent of this engagement and the successful application of outcomes to science and management varies regionally and among types of fisheries. A collaborative model that emphasizes knowledge coproduction with stakeholders better identifies research needs and conservation threats, and influences research and policy outcomes. Stakeholder integration can be facilitated by nongovernment organizations, such as boundary organizations. Bonefish and Tarpon Trust is a science-based, conservation organization founded in 1998 by recreational fishers and fishing guides that focuses on marine recreational fisheries in the Caribbean Sea and western North Atlantic Ocean. The Trust engages fishers directly, incorporating their knowledge and perspectives to identify conservation concerns, shape research, contribute to data collection, and disseminate information, and work with resource managers and scientific researchers to address conservation and management needs. This approach is demonstrated in case studies that show integration of recreational fishers in science, assessment of conservation threats, and application of findings to management for the recreational flats fishery in the Caribbean Sea and western North Atlantic Ocean, in the context of broader efforts of stakeholder collaboration toward actionable science to inform management.</p>","PeriodicalId":12389,"journal":{"name":"Fisheries","volume":"49 12","pages":"565-576"},"PeriodicalIF":2.4,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jim was a beloved father, husband, and grandfather, and a gifted research biologist, agency administrator, consultant, writer, and woodcarver. He died April 28, 2024 in Portland, Oregon. Jim was our mentor and friend. His unconventional career path left an extraordinary legacy to salmon conservation.&lt;/p&gt;&lt;p&gt;Jim enlisted in the U.S. Marine Corps and served for 4 years immediately after graduating high school. He was proud of his military service. In 1973, after receiving his Oregon State University MS in fisheries and working for a few years as a consultant, Jim took a research position with the Oregon Department of Fish and Wildlife. He rose quickly through the agency ranks to become head of the Research Section in 1979 and Assistant Chief for the Department's entire Fish Division in 1983. During 15 years of state government service, Jim nudged the agency toward a more rigorous science-based approach to salmon conservation and fisheries management. The rapidly growing research group thrived under his capable leadership. As Assistant Chief of Fisheries, Jim assumed responsibility for developing species management plans, including the first statewide plans for Coho Salmon &lt;i&gt;Oncorhynchus kisutch&lt;/i&gt; and Chinook Salmon &lt;i&gt;O. tshawytscha&lt;/i&gt;, steelhead &lt;i&gt;O. mykiss&lt;/i&gt;, and native trout.&lt;/p&gt;&lt;p&gt;In 1988 Jim began working with AFS Endangered Species Committee members Willa Nehlsen and Jack Williams on a broad West Coast status assessment of Pacific salmon stocks. The seminal 1991 paper in &lt;i&gt;Fisheries&lt;/i&gt; titled, “Pacific Salmon at the Crossroads: Stocks at Risk from California, Oregon, Idaho, and Washington,” made it painfully clear that salmonid decline was not confined to a few scattered watersheds. The paper's list of several hundred at-risk stocks of Pacific salmon, steelhead, and Coastal Cutthroat Trout &lt;i&gt;O clarkii&lt;/i&gt; revealed a systemic management failure over a vast northern Pacific region.&lt;/p&gt;&lt;p&gt;Recurring fishery management failures motivated Jim's determined search to understand the historical and ecological roots of the salmon crisis. To focus his search, Jim traded his prominent role as a state fisheries administrator to become a field biologist for the Jamestown S'Klallam Tribe on Washington's Olympic Peninsula in 1988. Three years later, he became an independent consultant to ensure the flexibility to set his own agenda. Over the next decade Jim and his coauthors published dozens of peer-reviewed scientific papers, book chapters, and technical reports about the ultimate sources of salmon decline and alternative strategies for recovery. Jim served on numerous scientific review panels and provided technical advice for salmon studies and recovery programs from the Skeena River, British Columbia, to t","PeriodicalId":12389,"journal":{"name":"Fisheries","volume":"49 9","pages":"440"},"PeriodicalIF":2.4,"publicationDate":"2024-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fsh.11167","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142160254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
