Stock enhancement programs often involve the introduction of hatchery‐reared fish into wild environments, with the goal of increasing the abundance of a particular stock. To measure the success of stocking efforts for depressed populations, hatchery‐reared individuals must be distinguishable from naturally spawned fish, potentially many years after release. Biological tags are attractive due to their ability to batch‐mark whole cohorts in a cost‐effective manner, with minimal disruption to hatchery procedures and reduced handling stress inflicted on individuals during the marking process. Elemental marking may occur naturally or via deliberate manipulation of the concentration of specific elements to create recognizable elemental signatures in the hard structures of fish (e.g., fin rays and otoliths). In this study, elemental signatures in the fin rays of known hatchery‐released Lake Sturgeon Acipenser fulvescens (ages 1–7) were quantified via laser ablation (LA) inductively coupled plasma–mass spectrometry (ICP‐MS) to assess whether the ambient water chemistry in a groundwater‐fed hatchery would create an elemental signature that facilitated discrimination of hatchery‐reared individuals from those naturally spawned in the wild. The concentrations of divalent trace elements, particularly Mn, within the first growth band of hatchery‐reared fish were significantly different from those of wild conspecifics, allowing us to accurately classify hatchery‐ versus wild‐spawned individuals with 99% success. In addition, we conducted a preliminary experiment to test the validity of two separate 24‐h immersions in 86Sr and 137Ba (immersions were conducted 30 d apart) to induce multiple combination marks in the fin rays of juvenile Lake Sturgeon. Fin rays collected 60 d after the second immersion were analyzed for isotopic ratios via LA ICP‐MS, and results indicated that elemental marking at both time points was achieved with 100% success. Induction of a combination of isotopic signatures could enable hatcheries to track the success of families or stocking groups within a single year‐class or across multiple year‐classes.

“…The most straightforward application of otolith geochemistry is probably with respect to fish species that migrate between fresh and marine or brackish waters (Kafemann, Adlerstein & Neukamm, 2000;Rohtla et al, 2015;Secor, 1992). In the meantime, non-essential trace elements such as strontium (Sr) and barium (Ba) are also incorporated to otoliths as mimics of Ca (Campana, 1999;Loewen, Carriere, Reist, Halden & Anderson, 2016). In the meantime, non-essential trace elements such as strontium (Sr) and barium (Ba) are also incorporated to otoliths as mimics of Ca (Campana, 1999;Loewen, Carriere, Reist, Halden & Anderson, 2016).…”

“…Otoliths were analysed for 86 Sr and 43 Ca in the WM Keck Collaboratory of Plasma Spectrometry, OregonState University. Otolith Sr:Ca ratios are therefore mostly driven by freshwater Sr:Ca ratios (see also Brown & Severin 2009), but freshwater Ca concentration seems to be the most influential factor in extremely hypocalcemic environments due to the positive effect this environmental setting has on Sr uptake kinetics(Loewen et al, 2016). A continuous line scan was traced from core to edge.…”

Brown trout Salmo trutta L. parr were sampled from 21 Estonian and three Finnish streams to investigate whether national sea trout parr surveys sample the progeny of anadromous or resident maternal parents. Otolith Sr:Ca core values were used and validated as a tool for distinguishing between the progeny of the two forms. In Estonia (n = 283), 92% of the parr were the progeny of anadromous maternal parents, and 8% were the progeny of resident maternal parents, whereas in Finland (n = 24), the respective proportions were 79% and 21%. Variation in the maximum otolith Sr:Ca core values among progeny of anadromous maternal parents indicated that some adult females may enter fresh waters several months before spawning. It was concluded that easily accessible locations situated up to 30 km from the sea largely contain progeny of sea trout, whereas sites with poor connectivity with the sea can be dominated by progeny of resident trout. This study demonstrated that the method applied provided an effective means to distinguish between the progeny of sea trout and resident brown trout.

In the context of the River Rhône restoration programme, the objective of this study was to assess the dispersal and population connectivity of the European chub, Squalius cephalus (Linnaeus, 1758) in a section of the natural, free‐flowing part of the lower River Rhône. The elemental water signatures for Sr:Ca and Ba:Ca were measured at seven stations within the river section, including its tributaries and backwaters, to determine whether they could be differentiated by microchemistry. From August to October the signatures differed among three sectors of the study reach: the Rhône; the Ardèche; and the backwaters. The elemental signatures of the otoliths of 178 young‐of‐the‐year (YOY) chub from the stations were measured to assess spawning areas and identify early migratory life histories. Analyses of otolith microchemistry identified the natal origin of 95% of the fish. Sr:Ca signatures of otoliths showed early downstream migration for 30.4% of the YOY chub; however, 70% of the fish recruited relatively close to their spawning origin suggesting a potential inshore retention of fish. The results showed (i) a non‐negligible contribution of the tributaries and backwaters in the recruitment of fish into the main channel; and (ii) the ability of chub to migrate over several kilometres during their first few months of life. This study shows that the combination of water and otolith microchemistry analyses of fish growth increases the understanding of fish life history. Moreover, the study revealed that half of the YOY fish from this river section came from the tributaries and the other half came from reproduction in the River Rhône (despite its high anthropization). These methods offer promising future applications of otolith microchemistry for river management in the context of ecological rehabilitation, especially to assess the effectiveness of measures applied in the restoration of floodplain connectivity for riverine fish population conservation.
