“…Three known-stocked individuals were not classified as being of JWFH origin, although the Sr:Ca values of the first 5 lm of the laser-ablation transect near the fin ray core for each of these individuals were within the range of the JWFH Sr:Ca signature. Nevertheless, the results of this study are consistent with previous investigations, which demonstrated that otolith Sr:Ca (and other naturally-occurring markers) can be used to identify hatchery-reared individuals with a high degree of accuracy in populations consisting of hatchery-origin and wild fish (Bickford & Hannigan 2005;Zitek et al 2010;Wolff et al 2013). More thorough sampling of the fin ray core with a pattern of laser-ablated spots or a raster would likely increase the probability of detecting the hatchery Sr:Ca signature in the fin ray core.…”

The effectiveness of pelvic fin ray microchemistry of muskellunge Esox masquinongy Mitchill to identify stocked individuals along with the potential to identify naturally reproduced fish were evaluated. Fish and water samples were obtained from one hatchery and seven lakes with natural differences in water Sr:Ca to determine whether locationspecific environmental signatures were recorded in sectioned muskellunge pelvic fin rays, including fish of known environmental history. Water and fin ray Sr:Ca were strongly correlated. Six lakes in Illinois possessed Sr:Ca signatures that were distinct from the hatchery where muskellunge were raised, resulting in pronounced shifts in Sr:Ca across sectioned fin rays of stocked fish. Hatchery and lake-specific Sr:Ca signatures were stable across years. Sixteen of 19 individual fish known to have been stocked based on PIT tags implanted at stocking were correctly identified as hatchery-origin fish using fin ray core Sr:Ca. Results also indicated that the hatchery Sr:Ca signal can be retained for at least seven years in fin rays of stocked fish. Fin ray microchemistry is a non-lethal approach for determining environmental history of muskellunge that could be used to assess movement patterns in lake and river systems and the degree to which muskellunge populations are supported by natural reproduction and stocking.

“…The relative importance of water and dietary sources to the otoliths may change depending on Ca availability in the water column; as Ca concentration varies with salinity, freshwater fish may compensate for decreased water-Ca by deriving more ions from their food. There are also two studies carried out by an American team: the first [137] concerned the use of the 87 Sr/ 86 Sr isotopic ratios in fish otoliths to determine the origins of invasive piscivores in the Upper Colorado River Basin (UCRB, western USA); the second study [138] was carried out to determine whether 87 Sr/ 86 Sr and Sr/Ca signatures in otoliths, fin rays and scales of June sucker (JS, C. liorus) could be used to identify whether the stocking carried out for many years previously to prevent fish extinction in Utah Lake (USA) had created a naturally reproducing population. In the first study, fish were collected during 2004-2009 from reservoirs and rivers throughout the basin.…”

and ends with man. The environment-food interaction is clear, and the production of safe and quality food is an indispensable condition for human health. The globalization of the markets, in particular of food markets, means that a greater variety of food is proposed to consumers who want to know more about its geographical origin and characteristics. For this aim, food traceability is a tool of primary importance because it acts on both food safety and quality, in order to satisfy the needs of a demanding consumer, who is interested in the quality of the food he eats and in the controls about the veracity of the brands which protect it [1, 2]. The production of high-quality food is the first step to satisfying other important aspects, such as the development of a productive but sustainable agriculture and the control of marketing. Frequently, all this is delegated to the "labelling", which is incomplete by nature or easily manipulated. Only the use of a scientific method of identification and control of the geographical origin, independent of the "labelling" and therefore of the producer, enables us to answer in full important questions concerning food safety, food quality and consumer protection. In order to achieve good results in this field, a basic mandatory condition is to develop suitable "robust" analytical methods which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds; the latter are fuelled by the modern ease of transport and conservation of products in world markets. Numerous chemical, biological and genetic methods have been developed over time in order to verify the origin of foods [3]. In this paper, we will focus on mass spectrometry, in particular on the 87 Sr/ 86 Sr isotopic ratio measurement, in that it is a "robust" analytical technique, able to fulfil the requisites needed for traceability, both to satisfy the veracity of the geographical origin and to trace possible contaminated foods back to their origin. In particular, due Abstract Today, food traceability needs to develop suitable "robust" analytical methods, in terms of the precision and of the reliability of results, which can support modern legislative tools, aimed at guaranteeing food authenticity and origin and trying to avoid possible frauds. This review paper highlights the most recent results obtained with the use of the 87 Sr/ 86 Sr isotopic ratio technique, when applied to the traceability of the origin of different foods for human consumption, such as vegetables, beverages, dairy products, and meat and fish products. The instrumental techniques, with the relative methodologies and the quality of the final results, will be examined and commented.

“…As such, variation in elemental concentrations in the ambient environment alters the deposition of elemental signatures in hard structures, resulting in a biological tag (Wolff et al. ). Natural differences in ambient water chemistry reflected in the elemental signatures that accumulated in otoliths and fin rays during hatchery rearing were used to successfully identify the origin of known hatchery‐reared Muskellunge Esox masquinongy (Rude et al.…”

Alternatively, stable isotope marking involves deliberately manipulating the natural isotopic ratio of particular elements (e.g., 88 Sr/ 86 Sr and 138 Ba/ 137 Ba), which typically show little variation in the natural environment, to intentionally induce an elemental mark (MacLellan and Fargo ; Thorrold et al.…”

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.
