The Danube Salmon Hucho hucho, endemic to the Danube River basin, is one of the largest members of the salmonid family. Here, we describe the distribution, ecology, and status of this flagship species in the upper Danube River basin. We model the historical distribution of Danube Salmon in the Austrian Danube River basin based on a review of the literature and species records. Fish sampling data over

A Novel Technological Approach to Recover Aquatic Research Equipment from Depth Fisheries (IF 2.8) Pub Date : 2024-02-27 Kurtis A. Smith, Paul A. Bzonek, Jacob W. Brownscombe
Researchers are increasingly using biologging equipment (e.g., telemetry receivers, temperature loggers) to characterize the ecology of aquatic ecosystems. This equipment is commonly deployed at a wide range of water depths and greatly expands our capacity to remotely monitor aquatic ecosystems; however, equipment retrieval can be a major challenge. Here, we describe a technological solution to this

Updating Angling Records to Advance Sport Fish Conservation: A Case Study of IGFA's Black Bass World Records Fisheries (IF 2.8) Pub Date : 2024-01-24 Andrew T. Taylor, Zachary L. Bellapigna, Bruce G. Pohlot
As taxonomic studies revise our understanding of biodiversity, both fisheries managers and the angling public must adapt to best conserve fisheries. Unfortunately, communication gaps between scientists and anglers may result in lags and inaccuracies in the taxonomic information available to anglers. We updated the International Game Fish Association (IGFA)'s black bass Micropterus spp. world records

Fish Diversity and Use of Nearshore and Open-Water Habitats in Terminal Lakes Fisheries (IF 2.8) Pub Date : 2023-12-11 Zachary Bess, Aaron Koning, James Simmons, Erin Suenaga, Aldo San Pedro, Joshua Culpepper, Facundo Scordo, Carina Seitz, Suzanne Rhoades, Tara McKinnon, Ryan McKim, Karly Feher, Flavia Tromboni, Julie W. Regan, Sudeep Chandra
Terminal lakes face conservation challenges due to consumptive water use and changes in climate. We quantified the extent of the littoral and open water zones in 18 terminal lakes spanning five continents and show that lake level declines produce variable changes in littoral zone surface area. While littoral zones account for a small portion of the habitat in these lakes, 77% of the fish species inhabit

Understanding age and growth are important for fisheries science and management; however, age data are not routinely collected for many populations. We propose and test a method of borrowing age–length data across increasingly broader spatiotemporal levels to create a hierarchical age–length key (HALK).

Predation by Caspian terns Hydroprogne caspia is a factor limiting the recovery of some Endangered Species Act-listed populations of salmonids from the Columbia River basin, especially steelhead Oncorhynchus mykiss. This prompted the development and implementation of two separate management plans, one in the Columbia River estuary and the other in the Columbia Plateau region, to reduce the impact of

Managing Expectations from Intensively Monitored Watershed Studies Fisheries (IF 2.8) Pub Date : 2023-09-14 Peter Bisson, Tracy Hillman, Tim Beechie, George Pess
Intensively monitored watershed (IMW) studies, the intent of which is to quantify habitat restoration effects on salmonid populations, have been underway in the Pacific Northwest, USA, for more than two decades. Lack of population-level response to habitat improvements by target species in some IMWs may be related to incomplete knowledge of factors regulating fish abundance, excessively prolonged restoration

Declines in populations of Pacific salmon Oncorhynchus spp. in the Pacific Northwest have led to listings under the Endangered Species Act. One objective of current recovery efforts is the restoration of freshwater and estuarine habitats, which had been occurring prior to Endangered Species Act listing but increased dramatically afterwards. However, few listed populations are improving. We believe

Aging, Climate, and Invasions Threaten Reservoirs in the Mississippi River Basin Fisheries (IF 2.8) Pub Date : 2023-08-17 Leandro E. Miranda
Reservoirs in the Mississippi River basin are facing three momentous threats.

Fish mislabeling is a global issue with far-reaching consequences for both food security and biodiversity conservation. This practice involves the intentional or unintentional misidentification of fish species sold in markets and restaurants, often driven by economic gain or cultural preferences. The mislabeling of threatened fish species further exacerbates the problem. This manuscript focuses on

The Evolution of Trout Stream Management in the Black Hills, 1883–2023, as Evidenced Through Hatchery Activities and Stocking Fisheries (IF 2.8) Pub Date : 2023-08-09 Dennis L. Scarnecchia, Shaylee Martling, Michael Barnes
In this paper, we review and synthesize trout management philosophy and policies for Black Hills streams in the states of South Dakota and Wyoming through the roles of hatcheries, fish stocking, and natural production from 1883 to 2023. We identified three specific fisheries management time periods (eras) in the Black Hills: (1) the early management–fry stocking era (pre-1950), (2) the catchable-trout

Inadvertent Hatchery Rainbow Trout Oncorhynchus mykiss Discovered in Native Westslope Cutthroat Trout Oncorhynchus clarkii lewisi Habitat: A Cautionary Tale Fisheries (IF 2.8) Pub Date : 2023-08-08 Samuel L. Bourret, Jill M. Janak, Tim J. Linley, Megan K. Nims, Geoffrey A. McMichael
Fish hatcheries across North America release billions of fish into the wild every year to augment harvest opportunities in sport, commercial, and tribal fisheries, as well as to recover depressed populations. Despite these benefits, wild fish populations may be negatively affected when hatchery fish compete and/or hybridize with native species. Native Westslope Cutthroat Trout Oncorhynchus clarkii

Long-Term Standardized Sampling as a Tool for Evaluating Management Actions: BACI Analysis to Reevaluate Predatory Control of Stunted Crappie with Saugeye Fisheries (IF 2.8) Pub Date : 2023-07-03 Daniel E. Shoup, Dray D. Carl
Field evaluations of management manipulations are rarely conducted, in part because they are difficult to design and require large sampling effort. However, many commonly used management approaches have <50% success rate, indicating the need for more research. Herein, we provide a case study illustrating how historic standard sampling data from Oklahoma were used to design robust before–after control–impact

Each year, thousands of fishes are tagged with electronic devices to study their biology and inform fisheries management. Such research assumes that the process of capturing, tagging, and then holding fish to allow them to recover before release (i.e., the “tagging process”) does not alter the physiology, behavior, and survival of these fish. However, the fish can experience physiological challenges

How Fishery Managers Can Harness the Power of the Crowd: Using Citizen Science and Nontraditional Data Sources in Fisheries Management Fisheries (IF 2.8) Pub Date : 2022-11-14 Laura Oremland, Abigail Furnish, Julia Byrd, Richard Cody
A constant challenge in fisheries stock assessment and management is having sufficient data to inform research and analyses. Nontraditional data sources like citizen science, when collected and applied appropriately, can help fill such data gaps. Use of nontraditional data sources is on the rise, but its use and application in fisheries science and management remains largely untapped. In order to examine
