“…Despite the wide distribution throughout Central and South American Atlantic coast, the highest white croaker landings occur between the Brazilian southeastern (Costa et al, 2014;Mulato et al, 2015) and the north of Argentina coast (Volpedo, Cirelli, 2006). Similarly to most exploited fishery resources, M. furnieri is under over-exploitation, as results of poor policies and management of fisheries resources in Brazil, Uruguay and Argentina (MMA-REVIZEE, 2006;Castello, 2007).…”

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.

“…Several authors agree in discriminating the Bahia Blanca region from the rest (Cotrina, 1986;Figueroa & Astarloa, 1991;Astarloa & Ricci, 1998;Volpedo & Cirelli, 2006). Marquez & Pereira (2013), based in studies of Pereira et al (2009) andD´Anatro et al (2011) suggest that the Rio de la Plata front spawners and those from coastal marine waters of Uruguay and southern Brazil are genetically distinct enough to be considered distinct populations.…”

“…Astarloa & Ricci (1998) compared meristic counts in the same latitudinal range and observed three groups: the Atlantic Uruguayan coast, the La Plata River Estuary and Bahia Blanca. Volpedo & Cirelli (2006) compared the otolith chemical composition (Cd/Ca, Cu/Ca, Mg/Ca, Sr/Ca and Zn/Ca ratios) along the Argentinian coast and their results suggested two different stocks from the La Plata River Estuary to Mar del Plata (35°-38°S) and southwards up to San Blás (39°-41°S). Maggioni et al (1994), failed to detect stock differences from Rio Grande in Brazil (33°S) to Bahia Blanca, Argentina (40°S) based in alloenzymes electrophoresis.…”

ABSTRACT. The whitemouth croaker Micropogonias furnieri is a demersal coastal and estuarine sciaenid fish intensely exploited by small and large scale fisheries in Brazil, Uruguay and Argentina between 22° and 40°S. To study the stocks structure of the whitemouth croaker along southeastern (SEB) and southern Brazil (SB) between 22°28' and 33°53'S, morphometric, meristic and growth data were collected during a bottom trawl survey. Consistent differences between different latitudes were not observed neither for the univariate comparisons of the number of gill rakers and dorsal and pectoral fin rays nor for five morphometric measurements. A principal component analysis of the five morphometric measures did not show a geographical grouping pattern. However, the age structure and growth differed significantly between south and north of Cape Santa Marta Grande (29•S). Former references and this study support the existence of two independent stocks of whitemouth croaker in southeastern and southern Brazil and diverse published studies indicate some degree of mixture between fishes spawning along southern Brazil, Uruguay and Argentina. In terms of access of the fleets there are three jurisdictions: along SB and SEB, where only Brazilian boats fish, in the common fishery zone of Uruguay and Argentina where both countries fish and south of 39ºS, where only Argentinian boats can fish but where the whitemouth croaker is not an important target. Efficient management requires the identification of management units based in stocks structure, life history, distribution of the fisheries and jurisdictions. When all these factors are taken into account, excluding local coastal small scale fisheries management, three geographical management units were identified in the shared waters of Argentinian and Uruguayan waters, southern Brazil and southeastern Brazil.

La corvina Micropogonias furnieri es un pez demersal costero y estuarino de la familia Sciaenidae abundante e intensamente explotado por flotas costeras e industriales entre el sureste de Brasil (22°S) y el norte de Argentina (40°S). Para el estudio de la estructura de los stocks de la corvina blanca a lo largo del sureste y sur de Brasil, se obtuvieron datos morfométricos, merísticos y de crecimiento a lo largo de la costa sur (SB) y sudeste (SEB) de Brasil entre las latitudes 22º28'S y 33º53'S. No se encontraron diferencias significativas entre las diferentes latitudes de pesca en el número de radios branquiales, rayos de las aletas dorsal y pectoral, ni para las cinco medidas morfométricas. El análisis de componentes principales de las cinco mediciones morfométricas no mostró un patrón de agrupación geográfica. Sin embargo, la estructura de edad y crecimiento difirió significativamente entre el sur y norte del Cabo Santa Marta Grande (29°S)....

“…Differences in otolith chemistry have been used for stock discrimination, analyses of population structure, reconstruction of the environmental history, and ecosystem monitoring (e.g. Campana 1999, Volpedo and Cirelli 2006, Woods et al 2010. However, only a few studies have addressed the question whether inter-population differences in otolith traits are genetically encoded or the result of differences in certain habitat parameters (Torres et al 2000, Stransky et al 2008, Lombarte et al 2010, Vignon and Morat 2010.…”

SUMMARY: Inter-population differences in otolith shape, morphology and chemistry have been used effectively as indicators for stock assessment or for recognizing environmental adaptation in fishes. However, the precise parameters that affect otolith morphology remain incompletely understood. Here we provide the first direct support for the hypothesis that inter-population differences in otolith morphology are genetically encoded. The study is based on otolith morphology and two mitochondrial markers (D-loop, 16S rRNA) of three natural populations of Aphanius fasciatus (Teleostei: Cyprinodontidae) from Southeast Tunisia. Otolith and genetic data yielded congruent tree topologies. Divergence of populations likely results from isolation events in the course of the Pleistocene sea level drops. We propose that otolith morphology is a valuable tool for resolving genetic diversity also within other teleost species, which may be important for ecosystem management and conservation of genetic diversity. As reconstructions of ancient teleost fish faunas are often solely based on fossil otoliths, our discoveries may also lead to a new approach to research in palaeontology.Keywords: Cyprinodontidae, phylogeography, gene flow, local adaptation, otolith morphometry, mitochondrial markers. RESUMEN: Las diferencias inter-pobLacionaLes en La morfoLogía deL otoLito de AphAnius fAsciAtus (cyprinodontiformes) se codifican genéticamente. -Las diferencias en la forma del otolito entre poblaciones, la morfología o la química se han utilizado con efectividad como indicadores para la gestión de poblaciones o para el reconocimiento de adaptaciones ambientales en peces. Sin embargo, los parámetros precisos que afectan la morfología del otolito permanecen sin ser entendidos completamente. Aquí nosotros presentamos la primera evidencia directa para la hipótesis de que las diferencias inter-poblacionales en la morfología del otolito están codificadas genéticamente. El estudio se basa en la morfología del otolito y dos marcadores mitocondriales (D-loop, 16S rRNA) de tres poblaciones naturales de Aphanius fasciatus (Teleostei: Cyprinodontidae) del sudeste de Tunez. Los datos de otolitos y genéticos ofrecen tres topologías congruentes. Aparentemente la divergencia entre poblaciones resulta de los procesos de aislamiento durante los descensos del nivel del mar en el Pleistoceno. Proponemos que la morfología del otolito es una herramienta muy valiosa para entender la diversidad genética también con otras especies de peces, que puede ser importante para la gestión de los ecosistemas y la conservación de la diversidad genética. Ya que las reconstrucciones de la fauna antigua de peces teleósteos se basan a menudo en otolitos fósiles, nuestro hallazgo puede también ser importante como nueva aproximación en las investigaciones palentológicas.
