“…Although there is a known positive correlation of Sr:Ca with salinity and Ba:Ca with freshwater (Elsdon & Gillanders 2005, Sturrock et al 2012, Reis-Santos et al 2013b, the mean concentrations of both element:Ca ratios in the otolith edge were not significantly different be tween individuals of the same year class caught in the neritic and littoral zones (Mann-Whitney U = 290 and p > 0.05 for Sr:Ca; U = 268, p > 0.05 for Ba:Ca). We hypothesize that the salinity difference, as well as the freshwater input, was not large en ough in this case to produce distinct otolith chemical signatures between the 2 sampled habitats, hindering our ability to use otolith chemistry to dis entangle movements between these 2 proximate coastal marine areas (as poin ted out by Albuquerque et al 2012 for Sr:Ca and salinity ranges of these areas).…”

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 trabajo se encontró una tendencia similar para las relaciones Sr:Ca del agua y otolitos. Además, si bien el estuario del Río de la Plata presenta (Albuquerque et al 2012). Ibáñez et al (2012) used Sr:Ca ratios to study displacement patterns of mugilid species in the Caribbean Sea, while Hedger et al (2008) applied this methodology to other salinity-tolerant species of the Northern Hemisphere, including Anguilla rostrata.…”

“…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.…”

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.

“…Some years later, Cabral (2002) did not succeed in validate the findings of Castelo (1986) and raised doubts on the annual formation of those rings. For Albuquerque et al (2012), the inclusion of checks as annuli rings results in overestimation of M. furnieri age in the Patos Lagoon estuary by both, Castello (1986) and Cabral (2002). For the range of considered ages, the radius average of large fishes did not tend to decrease because the higher age can be too far from the maximum age found.…”

1Studies on age and growth of fish populations have direct application in fisheries and contribute for policies of conservation. Our aim was update information on the Micropogonias furnieri growth parameters based on sagittae otoliths annulis readings, and we expected that the studied population from Southeast Brazil can reach more longevity than the reported in the available literature. We examined 286 individuals between August-2010 and July-2011 from Ubatuba Bay, SP. The Total Length ranged 200-480 mm. The determined growth parameters were: Males, L ∞ =523.4mm, k = 0.05×year -1 , t 0 = -8.78 year; Females L ∞ = 573.5mm, k = 0.06 × year -1 , t 0 = -7.49 year. The MI and % of edge type evidenced the formation of one ring per year during autumn/winter, coinciding with low temperature and low growth rate. These results differed from those reported for the Vazzoler's Population I (summer), and we detected higher longevity (45-48 years) as compared with the recorded in the available information.Keywords: Coastal fishes, Growth parameters, Longevity, Marginal increment, Ubatuba.Estudos de idade e crescimento de peixes têm aplicação direta na biologia pesqueira e contribuem para medidas de conservação.
