“…For example, Bradbury et al (2008) has reported values ~2.3 mmol/mol for Osmerus mordax (Mitchill, 1814) while Smith, Kwak (2014) reported values of ~3 mmol/mol for Gobiomorus dormitor Lacepède, 1800. However, euryhaline species were associated with significantly higher values of reference, as Mugil cephalus Linnaeus, 1758 (Sr:Ca=3.3 mmol/mol) (Fowler et al, 2016), Genidens barbus (Lacepède, 1803) (Sr:Ca=3.75 mmol/mol) (Avigliano et al, 2017b) and Zenarchopterus dunckeri Mohr, 1926 (Sr:Ca=4.2 mmol/ mol for freshwater-brackish) (Kanai et al, 2014).…”

“…For this reason, the Sr:Ca ratio of otolith has been widely used to infer migratory and population aspects of several species (Avigliano, Volpedo, 2016); for example Genidens barbus (Avigliano et al, 2015a(Avigliano et al, ,b, 2016a(Avigliano et al, , 2017b, Odontesthes bonariensis (Valenciennes, 1835) (Avigliano, Volpedo, 2013;Avigliano et al, 2014Avigliano et al, , 2015c, Mugil liza Valenciennes, 1836 7 e170055 [7] (Callicó Fortunato et al, 2017), Lycengraulis grossidens (Spix & Agassiz, 1829) (Mai et al, 2014), Micropogonias furnieri (Desmarest, 1823) (Albuquerque et al, 2012) and P. lineatus (Avigliano et al, 2016b(Avigliano et al, , 2017a. Particularly in P. lineatus it has been used the otolith microchemistry (Sr:Ca, Ba:Ca and Zn:Ca ratios) as well as otolith and scales morphometry in order to identify different nursery areas (Avigliano et al, 2016b(Avigliano et al, , 2017a.…”

“…In estuaries, salinity often has a positive correlation with otolith Sr:Ca when the freshwater end-member has lower Sr:Ca than sea-water (Secor, Rooker, 2000;Kraus, Secor, 2004;Martin et al, 2004;Sturrock et al, 2012). The techniques used to study ontogenetic changes of Sr:Ca ratio in otoliths include spot and line scan analysis by electron probe microanalysis (EPMA), microproton-induced X-ray emission (micro-PIXE) (Lin et al, 2007;Hedger et al, 2008;Daros et al, 2016), and more recently laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) (MoralesNin et al, 2014;Fowler et al, 2016;Kissinger et al, 2016;Avigliano et al, 2017b;Callicó Fortunato et al, 2017).…”

The streaked prochilod, Prochilodus lineatus, represents the most important fishery in the La Plata Basin (South America). Our objective was to analyze brackish environment use by the streaked prochilod captured from Paraná and Uruguay rivers. To accomplish this, lapillus otolith sections were analyzed for Sr:Ca with laser ablation-inductively coupled plasma-mass spectrometry (LA ICP-MS) to infer habitat use of fish. To the interpretation of transects, a threshold that represents the transition between freshwater and brackish environments was calculated using the Sr:Ca ratio of the otolith edge of specimens captured in the first section of the La Plata Estuary (salinity ≥ 0.5 PSU). The percentage of fish using the estuary was higher in the Paraná (37%) than the Uruguay River (5%). Change-point analysis showed that fish entered the estuary between 1 and 3 times throughout life at a wide range of ages (0-15 years). These incursions had no obvious periodicity. This information should be integrated into future management actions, which should also be specific to each area since migration patterns differ between the major rivers of the basin.Keywords: Connectivity, Freshwater resident, Laser ablation, River migration, Streaked prochilod.El sábalo, Prochilodus lineatus, representa la pesquería más importante en la Cuenca del Río de la Plata (Sudamérica). Nuestro objetivo fue analizar el uso del hábitat estuarino del sábalo proveniente de los ríos Uruguay y Paraná. Para esto, se analizó la relación Sr:Ca en secciones de otolitos lapilli por ablación láser acoplada a espectrometría de masas con fuente de plasma de acoplamiento inductivo (LA ICP-MS) para inferir el uso de hábitat. Para interpretar las transectas, un umbral que representa la transición entre los ambientes de agua dulce y estuarino, fue calculado usando la relación Sr:Ca del borde del otolito de especímenes capturados en la primera sección del estuario del Plata (salinidad ≥0.5 UPS). El porcentaje de peces que usaron el estuario fue más elevado para el Paraná (37%) en relación al Uruguay (5%). El análisis de cambio puntual mostro que los individuos ingresan al estuario entre 1 a 3 veces a lo largo de la vida en un amplio rango de edades (0-15 años). Las incursiones no mostraron una periodicidad notoria. Esta información debería integrarse a futuras acciones de manejo que deberían ser específicas para cada área considerando los patrones de migración que difieren entre los grandes ríos de la Cuenca.Palabras clave: Ablación laser, Agua dulce residente, Conectividad, Migración de rio, Sábalo.

“…We assume that Sr:Ca variations measured from core-to-edge in each transect represent different hydrochemical (salinity) areas encountered by the fish during its life (Freshwater et al, 2015;Hegg et al, 2015). These changes do not necessarily imply movements between freshwater and brackish habitats, because stable Sr:Ca signatures change can be found within these habitats (Avigliano et al, 2017a;Freshwater et al, 2015;Hegg et al, 2015). CPA determined whether there had been a change in the underlying process that generated the sequence of events and, if so, identified where the change occurred.…”

Otolith core-to-edge Sr:Ca ratio was determined by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) to analyze the salinity-habitat migration history of the silverside, Odontesthes bonariensis, within the Uruguay River (freshwater) and Río de la Plata Estuary (estuarine water) (Plata Basin, South America). Regular core-to-edge oscillations in Sr:Ca suggest that the silverside makes annual migrations between freshwater (<1 PSU) and brackish (>1 PSU) habitats, with no evidence of marine incursion or non-migratory individuals. Empirical equations that represent the relationship between conductivity/salinity and otolith Sr:Ca ratio were used to identify where in an otolith an individual transitioned between freshwater and brackish habitats. In most specimens, the first migration between habitats likely occurred within the first year of life. Average numbers of changes between stable Sr:Ca signatures (sites with different salinities) determined by Change-Point analysis were similar from Uruguay (8.9±3.7) River and Río de la Plata Estuary (7.5±2.5) for comparable age fish (p<0.05), suggesting that habitat use is similar in both collection sites.

The white mullet, Mugil curema, is a widely distributed euryhaline species, the migratory behaviour of which is poorly understood. The objective of this work was to study the large‐scale habitat use of this species for the first time. Several environments were considered, such as euryhaline and hypersaline lagoons, the sea, and a river, distributed in the Central Pacific (Mexico) and Atlantic (Gulf of Mexico, Caribbean Sea‐Venezuela, and north‐eastern Brazil). Otolith core‐to‐edge Sr/Ca ratios of 163 fish, determined by laser ablation inductively coupled plasma mass spectrometry, were used to study the salinity‐habitat migration history of the fish. Fish from Mexico (Tamiahua Lagoon, n = 4; Alvarado Lagoon, n = 2), Venezuela (n = 1), and Brazil (n = 12) (11.1% of the total) showed high Sr/Ca values at early life stages and were classified as marine estuarine opportunists. Two specimens (from Alvarado Lagoon and Balsas River, Mexico) showed Sr/Ca values consistently below the high salinity guide value (salinity < 33.5). For the rest of the fish (87.1%), the Sr/Ca ratio suggested a displacement from the estuary towards the sea or hypersaline environments, and so these fish were classified as estuarine migrants. A change‐point analysis identified six individuals with a single stable otolith Sr/Ca signature through ontogeny (three from Brazil, one from Venezuela, and two from Tamiahua Lagoon, Mexico), suggesting limited displacement between environments with different salinities. The rest of the individuals showed between two and 10 changes in stable Sr/Ca signatures (mean = 4.07 ± 1.85). The highest number of changes in Sr/Ca ratio (4.87 ± 1.1) was found in fish from Laguna Madre (Mexico) and the lowest was found in fish from Brazil (3.27 ± 1.70) (H = 19.8, p = 0.002). Otolith Sr/Ca time series suggest that the migratory estuarine pattern is the most common throughout the study area. This work highlights that the sustainable use of M. curema depends on the conservation of estuaries and the corridors between them and other environments such as lagoons, rivers, mangroves and the sea.
