“…Notably, organic contaminants were negatively associated with Se_GPx, which aligns with earlier observations using the same species also collected in the North Atlantic (Alves et al, 2016). These negative correlations between GPx and contaminant concentrations have also been reported for other pelagic (Vélez-Alavez et al, 2013) and coastal (Somerville et al, 2020) shark species. Most contaminants correlated negatively with ROS and LPO measured in both liver and gills.…”

“…Because of these limitations, using non-lethal and minimally-invasive methods has become more common practice ( Jeffries et al, 2021 ). Molecular responses to a range of contaminant exposure have been tested with many non-lethal samples, including muscle ( Veldhoen et al, 2010 ; Somerville et al, 2020 ), fins ( Andreasen et al, 2006 ; Veldhoen et al, 2013b , 2014 ; Baillon et al, 2016 ), mucus ( Arukwe and Røe, 2008 ; Bahamonde et al, 2019 ; Bulloch et al, 2020 ), blood and plasma ( Arukwe and Røe, 2008 ; Rodríguez-Jorquera et al, 2019 ), gill ( Rees et al, 2005 ; Barriga-Vallejo et al, 2017 ), and scales ( Aerts et al, 2015 ; Alves et al, 2016 ) ( Figure 1 ). However, when it comes to the intersection of contaminants, non-lethal sampling, and molecular work, there are few examples that analyze aspects of movement.…”

Non-Lethal Sampling Supports Integrative Movement Research in Freshwater Fish

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.

“…When ROS production exceeds removal, antioxidant defenses can be deactivated; this results in oxidative stress and macromolecule damage (lipid peroxidation, protein degradation, and disruption of DNA), cellular dysfunction, and/or death [9]. A correlation between trace elements accumulation and oxidative stress has been reported in aquatic organisms [1,[10][11][12][13][14][15][16]. However, several species show the ability to prevent oxidative damage caused by trace elements.…”

“…Sharks, due to the high position in the food chain, slow growth rates, and low elimination abilities [10,17], are able to bioaccumulate, or worse, to biomagnify several elements through the food chain [5,15,[18][19][20]. So far, information regarding the influence of the exposure to trace elements on shark health is scarce and fragmentary, often obtained in a limited number of species or in a restricted region of the world [21,22].…”

“…Little is known on the putative impact of trace elements accumulation on the oxidative status of animals. In this regard, the few data available, mainly derived from studies performed on epipelagic and demersal species (e.g., blue sharks [1], mako sharks [12], the Atlantic sharpnose shark [10]), suggested a correlation between several trace elements and the activity of antioxidant enzymes (e.g., SOD, CAT, and glutathione peroxidase (GPx)), as well as the levels of oxidation products (e.g., protein carbonylation and lipid peroxidation). However, a significant variability, possibly depending on environmental exposure and/or behavioral differences between populations, sex, or maturity stage, has emerged.…”

Marine pollution, due to the regular discharge of contaminants by various anthropogenic sources, is a growing problem that imposes detrimental influences on natural species. Sharks, because of a diet based on smaller polluted animals, are exposed to the risk of water contamination and the subsequent bioaccumulation and biomagnification. Trace elements are very diffuse water pollutants and able to induce oxidative stress in a variety of marine organisms. However, to date, studies on sharks are rather scarce and often limited to mercury. In this context, the present study aimed to analyze the accumulation of trace elements and their putative correlation with the onset of an oxidative status in the muscle of the lesser spotted dogfish Scyliorhinus canicula, from the Central Mediterranean Sea. Ecotoxicological analysis detected the presence of Pb, As, Cd, Mn, Zn, Ni, Cu, and Fe; no significant differences were observed between sexes, while a negative correlation was found between Pb and animal length. Analysis of oxidative stress markers showed either positive or negative correlation with respect to the presence of trace elements. Lipid peroxidation (TBARS) positively correlated with Zn, Ni, and Fe; SOD enzyme activity negatively correlated with Cu and Ni; LDH was negatively correlated with Fe and positively correlated with Pb. Moreover, positive correlations between the leukocyte count and Mn and Zn, as well as with LDH activity, were also observed. The data suggested that, in sharks, trace elements accumulation may affect oxidant and antioxidant processes with important outcomes for their physiology and health.
