“…In this work, the highest percentage of freshwater resident specimens was registered in the Uruguay River. However, it is not possible to affirm that these specimens are not migratory, as they could move long distances among environments with similar salinity and make no significant differences in Sr:Ca ratio of otolith (Avigliano et al, 2017a).…”

“…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.

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.

“…Fish were collected using trammel nets in the main courses of the Uruguay River (31°25.246′S–58°1.407′W, 31°59.105′S–58°9.599′W; Argentina–Uruguay international boundary), and in the Paraná River (27°25.467′S–58°48.133′W; Argentina–Paraguay international boundary; Figure ). These two areas of the Paraná and Uruguay rivers correspond approximately to the two main nursery areas (Avigliano, Domanico, et al, ). Fish were killed with percussive stunning (Van De Vis et al, ), placed on ice, and transported to the laboratory, where they were measured (standard length = SL) and the lapilli otoliths were extracted.…”

“…In the streaked prochilod, it was demonstrated that there are two main nursery areas in the middle and lower regions of the La Plata Basin (latitude 27–35°), where there are no dams and the migratory corridor is continuous (Avigliano, Fortunato, et al, ; Avigliano, Domanico, Sánchez, & Volpedo, ; Sverlij et al, ). These nursery areas correspond to the middle sections of the Paraná and Uruguay rivers, and it was reported that chemical signatures of otoliths make it possible to differentiate each other (Avigliano, Domanico, et al, ). In addition, a previous study has suggested that the contribution to the Basin of larvae (without considering the probability of recruitment) from the Paraná River nursery is significantly greater than the one from the Uruguay River (Fuentes, Gómez, Vegh Llamazares, Lozano, & Salva, ).…”

Stock composition studies using otolith fingerprints have scarcely been developed in freshwater systems. In this context, the La Plata Basin is the second largest fluvialmarine system of South America, where Prochilodus lineatus is the most important fishery resource. Despite the basin importance, estimation of mixed stock composition has not been explored yet. In this paper, the contribution of the two main nursery areas to two fishing stocks (Uruguay and Paraná rivers) of P. lineatus was evaluated using otolith's core microchemistry, considering two groups: subadult (2 years) and adult (4 years). Estimates were made using two maximum likelihood methods. Chemical composition of young-of-year fish caught in nursery areas in 2010 was used as baseline of the models, whereas chemical composition of the core of subadult and adult otoliths was used as sample of unknown origin. Results suggest that the subadult stock from Paraná was not mixed (contribution~100%), whereas the stock from Uruguay had a contribution from the Paraná nursery (1.5 ± 1.2-17.9 ± 3.96%). For the adults, the degree of mixing increased and the contribution from both nursery areas to the Paraná and Uruguay stocks varied between 14.8 ± 4.18% and 85.2 ± 4.18%, respectively. The potential application of otolith fingerprints and maximum likelihood mixture models is here highlighted for determining the relative importance of recruitment sources of fish in the La Plata Basin. Because the contributions of the different nursery areas shared among several nations in turn affect the composition of internationally shared stocks, comprehensive management agreements at the basin level are necessary.

“…Apart from determining a stock's productivity, the identification of spawning areas and migration patterns are crucial for developing sustainable fisheries management strategies (Colloca et al ., ). Elemental analysis of fish otoliths is a widely used methodology for identifying spawning areas and discriminating among stock components (Avigliano et al ., ; Kerr & Campana, ). The chemical composition of otoliths is a natural marker of habitat use due to the otolith's continuous growth throughout the fish's lifetime and the fact that the deposited otolith material is metabolically inert (Campana & Neilson, ).…”

The gross energy content of spawning batches and the microchemistry of sagittal otoliths in individual female bonga shad Ethmalosa fimbriata were compared between contrasting sampling sites at the Senegalese southern coast and inside the hypersaline Sine Saloum Estuary. Results show that females spawning in the estuary's middle reaches invested almost three times more energy into reproduction (115 ± 65 J g−1 body mass) than their neritic counterparts (39 ± 34 J g−1 body mass). Also, female otolith levels of Ba:Ca, Sr:Ca and Zn:Ca either differed significantly between study sites or could be linked to heterogeneous environmental variables. A quadratic discriminant function analysis provided evidence of segregated spawning populations of E. fimbriata in southern Senegalese waters.
