“…For instance, otoliths of G. geni dens showed average Ba:Ca ratios of approximately 0.08 in the estuary, which increased to ~0.13 in the freshwater portion of the Patos Lagoon (Pereyra 2015). Ba:Ca values ranging from 0.01 to 0.14 were also reported for Lycengraulis grossidens and Geni dens barbus collected along the Patos Lagoon salinity gradient (Mai et al 2014, Avigliano et al 2015. We recognize that inter-specific variations in otolith microchemistry may sometimes preclude comparisons between different species (Reis-Santos et al 2008).…”

“…Age determination using otoliths has already been validated for E. marginatus in this study area (Condini et al 2014b). All procedures for otolith chemical analysis followed Mai et al (2014). Each otolith section was scanned from the core to the edge using a 266 nm laser ablation system (CETAC LSX 100) coupled to an ELAN 6000 (Perkin Elmer -SCIEX) inductively coupled plasma-mass spectrometer (ICP-MS), and calcium ( ) and its estuarine zone in the state of Rio Grande do Sul, southern Brazil (A), showing the locations of the 2 sampling sites (rocky jetties and Carpinteiro Bank), as well as 2 sites related to salinity data (Est.…”

Otolith microchemistry (Sr:Ca, Ba:Ca) was used to evaluate habitat use patterns of the endangered dusky grouper Epinephelus marginatus in southern Brazil. Individual Sr:Ca profiles exhibited low variation, with an overall tendency to increase with age. Interestingly, individual Ba:Ca profiles presented 3 contrasting patterns: the first comprised most sampled individuals (> 80%), mostly indicative of the predominant use of marine waters throughout their life history; the second pattern (~10% of all individuals) indicated that dusky grouper may use or remain in or near estuarine waters for short time periods; finally, the third identified pattern (~5%) comprised individuals remaining in estuarine waters for long periods and provided the first evidence for this species of prolonged estuarine habitat use (over a year), in particular during juvenile life stages.

“…En este sentido, la relación Sr:Ca del otolito resultó ser buen marcador de hábitat para el pejerrey. Otros autores reportaron que la relación Sr:Ca del otolito es un buen indicador de hábitat para algunas especies eurihalinas de Sudamérica, como la sardina Lycengraulis grossidens (Mai et al 2014) y la corvina Micropogonias furnieri (Albuquerque et al 2012). Ibáñez et al (2012) utilizaron la relación Sr:Ca para el estudio de patrones de desplazamiento de diferentes especies de mugílidos del mar Caribe, mientras que Hedger et al (2008) aplicaron esta metodología para otras especies del hemisferio norte con gran tolerancia a la salinidad, como Anguilla rostrata.…”

“…In this sense, the otolith Sr:Ca ratio proved to be a good marker of habitat for O. bonariensis. It has also been reported to be a good indicator of habitat for two other South American euryhaline species, Lycengraulis grossidens (Mai et al 2014) and Micropogonias furnieri los índices que más contribuyeron a la discriminación sobre este eje fueron circularidad (CE = 2.27) y el factor de forma (CE = 2.05), seguidos de rectangularidad (CE = -0.51), SS/ SO (CE = -0.42) y elipticidad (CE = -0.04).

ABSTRACT. The silverside Odontesthes bonariensis is a euryhaline species native of South America and represents a very important fishing resource for the Plata Basin (Argentina and Uruguay). This study compares the Sr:Ca ratio of water as well as the Sr:Ca ratio and morphometry of the sagittal otolith of the silverside present in different environments (one salt lake, two freshwater dams, one lagoon, and one estuary) in order to evaluate the use of these variables as markers of habitat. The pattern of the Sr:Ca ratio in the water agrees with the one found in the otoliths, showing a positive relationship with the conductivity of the water. Univariate and multivariate analyses of variance indicated significant differences (P < 0.05) among the localities studied for the morphometric indices. The discriminant function analysis provided a high percentage of correctly classified individuals for the saltwater environment (100%) and the lentic water bodies and estuary (60-80%), circularity and form factor being the most relevant morphometric variables. These results indicate that the Sr:Ca ratio and otolith morphometry are good markers of habitat for this important resource.Key words: morphometry, Sr:Ca, otolith, Odontesthes bonariensis, Argentina. RESUMEN. El pejerreyOdontesthes bonariensis es una especie eurihalina nativa de Sudamérica y representa un importante recurso pesquero para la cuenca del Plata (Argentina y Uruguay). En este estudio se comparó la relación Sr:Ca del agua y la relación Sr.:Ca y morfometría de los otolitos sagittae de pejerreyes presentes en diferentes ambientes (un lago de agua salada, dos embalses de agua dulce, una laguna y un estuario) con el objetivo de evaluar el uso de estas variables como marcadores de hábitat. El patrón de la relación Sr:Ca del agua concuerda con la hallada en los otolitos, mostrando una relación positiva con la conductividad del agua. Los análisis univariados y multivariados indicaron diferencias (P < 0.05) entre las localidades estudiadas para los índices morfométricos. El análisis discriminante mostró un elevado porcentaje de individuos correctamente clasificados para el ambiente de agua salada (100%), los cuerpos de agua lenticos y el estuario (60-80%), siendo la circularidad y el factor de forma los índices morfométricos de mayor relevancia para esta clasificación. Estos resultados indican que la relación Sr:Ca y la morfometría del otolito son buenos marcadores de hábitat para este importante recurso.

The streaked prochilod Prochilodus lineatus (Valenciennes) is a commercially freshwater species from South America, distributed in the Plata basin. In the present work the morphometry (circularity, rectangularity, form factor, OL/OW and ellipticity indices) and chemistry (Sr:Ca, Ba:Ca, Zn:Ca) of lapilli otolith, and geometric morphometry of scales of streaked prochilod juveniles, in two sites in the Plata basin (Uruguay River and Estrella Wetland), were compared to determine if they are area-specific and to identify possible breeding areas. Otolith Ba:Ca ratios was 0.017±0.003 mmol/ mol for Uruguay River while for Estrella Wetland individuals was bellow the detection limits. Zn:Ca ratios tended to be higher for the latter (0.03±0.002 mmol/mol). Significantly high circularity and low rectangularity values were obtained for Estrella Wetland otoliths (p < 0.05), while no significant differences for form factor, OL/OW and ellipticity were observed between sampling sites. Considering all scale geometric morphometry variables, discriminant analysis showed a good percentage of classification of individuals (90.5% for Estrella Wetland and 85.7 % for Uruguay River). These results indicate that the otolith microchemisty and morphometry (circularity and rectangularity indices) and scale morphometry are good markers of habitat and represent a potential tool for identification of streaked prochilod nursery areas.El sábalo Prochilodus lineatus (Valenciennes) es una especie de importancia comercial de agua dulce de Sudamérica, distribuida en la cuenca del Plata. En este trabajo se comparó la morfometría (índices de circularidad, rectangularidad, factor de forma, OL/OW y elipticidad) y microquímica (Sr:Ca, Ba:Ca y Zn:Ca) del otolito lapilli, y la morfometría geométrica de las escamas de sábalos juveniles capturados en dos sitios de la cuenca del Plata (Río Uruguay y bañado la Estrella), para determinar si existen diferencias área-especificas e identificar posibles sitios de cría. La relación Ba:Ca del otolito fue 0.017±0.003 mmol/mol para el río Uruguay mientras que estuvo por debajo del límite de detección para los individuos del bañado la Estrella. La relación Zn:Ca tendió a ser más alta en el bañado la Estrella (0.03±0.002 mmol/mol). Se obtuvieron valores significativamente altos de circularidad y bajos de rectangularidad para el bañado la Estrella (p < 0.05), mientras que no se hallaron diferencias para el factor de forma, OL/OW y elipticidad. Considerando la morfometría geométrica de las escamas, el análisis discriminante mostró buenos porcentajes de clasificación (90.5% para el bañado la Estrella y 85.7 % para el Río Uruguay). Estos resultados indican que la microquímica y morfometría del otolito (índices de rectangularidad y circularidad) y la morfometría de las escamas son buenos marcadores de hábitat y representan una herramienta potencial para la identificación de sitios de cría del sábalo.
