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.

Technical note: Does scan resolution or downsampling impact the analysis of trabecular bone architecture?

The “gold standard” for the assessment of trabecular bone structure is high‐resolution micro‐CT. In this technical note, we test the influence of initial scan resolution and post hoc downsampling on the quantitative and qualitative analysis of trabecular bone in a Gorilla tibia. We analyzed trabecular morphology in the right distal tibia of one Gorilla gorilla individual to investigate the impact of variation in voxel size on measured trabecular variables. For each version of the micro‐CT volume, trabecular bone was segmented using the medical image analysis method. Holistic morphometric analysis was then used to analyze bone volume (BV/TV), anisotropy (DA), trabecular thickness (Tb.Th), spacing (Tb.Sp), and number (Tb.N). Increasing voxel size during initial scanning was found to have a strong impact on DA and Tb.Th measures, while BV/TV, Tb.Sp, and Tb.N were found to be less sensitive to variations in initial scan resolution. All tested parameters were not substantially influenced by downsampling up to 90 μm resolution. Color maps of BV/TV and DA also retained their distribution up to 90 μm. This study is the first to examine the effect of variation in micro‐CT voxel size on the analysis of trabecular bone structure using whole epiphysis approaches. Our results indicate that microstructural variables may be measured for most trabecular parameters up to a voxel size of 90 μm for both scan and downsampled resolutions. Moreover, if only BV/TV, Tb.Sp or Tb.N is measured, even larger voxel sizes might be used without substantially affecting the results.
