Estimating contributions from nursery areas to fish stocks in freshwater systems using otolith fingerprints: The case of the streaked prochilod in the La Plata Basin (South America)
(John Wiley & Sons Ltd, 2018-09)
Stock composition studies using otolith fingerprints have scarcely been developed in freshwater systems. In this context, the La Plata Basin is the second largest fluvial-marine system of South America, where Prochilodus ...
Spatial segregation and connectivity in young and adult stages of Megaleporinus obtusidens inferred from otolith elemental signatures: Implications for management
(Elsevier Science, 2018-08)
Boga Megaleporinus obtusidens is a teleost fish of economical and sport importance from Río de la Plata Basin (South America). Otolith core and edge elemental ratios (Ba:Ca, Cu:Ca, Li:Ca, Mg:Ca, Mn:Ca, Pb:Ca, Rb:Ca and ...
Inter-Annual variability in otolith chemistry of catfish Genidens barbus from South-western Atlantic estuaries
(Cambridge University Press, 2017-03)
The catfish Genidens barbus is a commercial species from South America. The aim of the present study was to examine the inter-Annual variability in estuary-specific chemical signatures of otolith cores (Ba:Ca, Mg:Ca, Mn:Ca, ...
Variability in age of a Southern Ocean myctophid (Gymnoscopelus nicholsi) derived from scatrecovered otoliths
(2020)
Myctophids are ecologically important in the Southern Ocean, where they occupy a central trophic position and are a key energy resource for top predators. However, understanding their population dynamics is limited by a ...
Otolith edge fingerprints as approach for stock identification of Genidens barbus
(2017)
The purpose of this paper is to assess the use of multi-elemental otolith fingerprints as a tool to delimit catfish Genidens barbus fish stocks in four estuaries from the southwestern Atlantic Ocean. Barium:Calcium (Ca), ...
Nursery areas and connectivity of the adults anadromous catfish (genidens barbus) revealed by otolith core microchemistry in the southwestern Atlantic Ocean
(Csiro Publishing, 2016-07)
The anadromous catfish, Genidens barbus, is a commercial and vulnerable species from South America. The aims of the present study were to assess whether the nursery areas can be discriminated by using microchemical signatures ...
Natural growth, otolith shape and diet analyses of Odontesthes nigricans Richardson (Atherinopsidae) from southern Patagonia
(Elsevier, 2015-03)
Age and growth, otolith shape and diet of Odontesthes nigricans were analysed in order to provide an insight into the life history of the species and furthermore, to assess their possible use as a tool for discriminating ...
Otolith shape and microchemistry revealing life history traits of introduced Chinook Salmon in Patagonia
(American Fisheries Society, 2018)
Biological invasions can drastically alter aquatic ecosystems and the societies that depend on them. Human activities propagate non-native species both intentionally and accidentally, which in some cases eliminate native ...
White mullet Mugil curema population structure from Mexico and Brazil revealed by otolith chemistry
(Wiley Blackwell Publishing, Inc, 2020-08-15)
The white mullet Mugil curema supports several fisheries in the neotropical region; nevertheless, the population structure is still elusive. The aim of this study was to assess the presence of adult management units and ...
Biometric Relationships between Otolith and Fish Size of the Main Demersal Resources of North Patagonia, Argentina
(Springer, 2020-05)
Allometric power equations are generated using otolith length and width in order to estimate the total length of five demersal species inhabiting the San Matias Gulf, the second largest gulf in Argentina. The selected fish ...
