“…See also a study of sample handling best practices to preserve RNA integrity in Vehniäinen et al (2019) . Due to its ease of use and the ability to store samples in the field, RNA later is often used in RNA and DNA-based field studies in fish biology ( Garseth et al, 2013 ; Teffer and Miller, 2019 ; Vehniäinen et al, 2019 ; Kazyak et al, 2021 ). By contrast, preserving tissues for DNA sampling can be done with a variety of field-ready methods due to its stability (reviewed in Nagy, 2010 ).…”

Freshwater ecosystems and fishes are enormous resources for human uses and biodiversity worldwide. However, anthropogenic climate change and factors such as dams and environmental contaminants threaten these freshwater systems. One way that researchers can address conservation issues in freshwater fishes is via integrative non-lethal movement research. We review different methods for studying movement, such as with acoustic telemetry. Methods for connecting movement and physiology are then reviewed, by using non-lethal tissue biopsies to assay environmental contaminants, isotope composition, protein metabolism, and gene expression. Methods for connecting movement and genetics are reviewed as well, such as by using population genetics or quantitative genetics and genome-wide association studies. We present further considerations for collecting molecular data, the ethical foundations of non-lethal sampling, integrative approaches to research, and management decisions. Ultimately, we argue that non-lethal sampling is effective for conducting integrative, movement-oriented research in freshwater fishes. This research has the potential for addressing critical issues in freshwater systems in the future.

“…At present, it is unclear if the population will adapt to the physiological requirements of a more northern climate. However, if the disjunct population persists, it may complicate future conservation efforts by confl ating results of individual assignment and mixed-stock analyses, both of which are extensively used to understand regional and range-wide threats to Atlantic Sturgeon recovery (e.g., Kazyak et al 2021 ).…”

Decades of Global Sturgeon Conservation Efforts Are Threatened by an Expanding Captive Culture Industry

After centuries of overexploitation and habitat loss, many of the world's sturgeon (Acipenseridae) populations are at the brink of extinction. Although significant resources are invested into the conservation and restoration of imperiled sturgeons, the burgeoning commercial culture industry poses an imminent threat to the persistence of many populations. In the past decade, the number and distribution of captive sturgeon facilities has grown exponentially and now encompasses diverse interest groups ranging from hobby aquarists to industrial-scale commercial facilities. Expansion of sturgeon captive culture has largely fallen outside the purview of existing regulatory frameworks, raising concerns that continued growth of this industry has real potential to jeopardize conservation of global sturgeon populations. Here, we highlight some of the most significant threats commercial culture poses to wild populations, with particular emphasis on how releases can accelerate wild population declines through mechanisms such as hybridization, introgression, competition, and disease transmission. We also note that in some circumstances, commercial captive culture has continued to motivate harvest of wild populations, potentially accelerating species' declines. Given the prevalence and trajectory of sturgeon captive culture programs, we comment on modifications to regulatory frameworks that could improve the ability of captive culture to support wild sturgeon conservation.
