Ontogenetic and sexual variation in the sagitta otolith of Menticirrhus americanus (Teleostei; Sciaenidae) (Linnaeus, 1758) in a subtropical environment
(Universidade de Sao Paulo, 2020-02)
This study aimed to verify variations in the form of the sagitta otolith of Menticirrhus americanus as to their ontogeny, sex and stage of such structure. Ontogenetically were found significant differences (p < 0.05) for ...
Nutritional condition and otolith growth of Engraulis anchoita larvae: The comparison of two life traits indexes
(Elsevier Science, 2019-03)
Engraulis anchoita larvae were captured in 16 surveys carried out at a fixed sampling station (EPEA) in the Argentinean Sea between 2008 and 2017. Nutritional condition and growth of 214 anchovy larvae were estimated through ...
Total length estimation of the Brazilian flathead Percophis brasiliensis, using morphometric relationships of skull, pectoral girdle bones, otoliths and specific body measures, in Argentine waters
(Wiley Blackwell Publishing, Inc, 2013-03)
Predictive regression equations were generated to estimate total length of the Brazilian flathead (Percophis brasiliensis) fish using skull and pectoral girdle bones as well as specific body and otolith lengths. All ...
Fish otolith microchemistry as a biomarker of the world's largest mining disaster
(2022-02-10)
The Fundão dam collapse occurred in late 2015, resulting in the largest disaster in the world involving mine tailings, releasing at least 50 million m3 of iron ore tailings into the Doce river basin (Brazil). Studies ...
Otolith morphology and feeding ecology of an Antarctic 3 nototheniid, Lepidonotothen larseni
(Cambridge University Press, 2013-05)
This study is based on the analysis of the stomach content and the morphology and morphometry of the three pairs of otoliths (sagitta, asteriscus and lapillus) of Lepidonotothen larseni (Lo¨nnberg) collected at the South ...
Otolith shape index: Is it a tool for trophic ecology studies?
(Cambridge University Press, 2019-11)
The aim of this study was to test the effective separation of shape indices of otoliths of three species belonging to the family Sciaenidae before and after in vitro digestion. We measured 328 sagittal otoliths and applied ...
Use of otolith strontium:calcium ratio as indicator of seasonal displacements of the silverside (Odontesthes bonariensis) in a freshwater-marine environment
(Csiro Publishing, 2013-04)
Strontium:calcium ratios were measured in sagittal otoliths of silverside (Odontesthes bonariensis) from a freshwater-marine environment (Paraná River Delta and River de la Plata River, South America) in order to understand ...
Is otolith microchemistry (Sr:Ca and Ba:Ca ratios) useful to identify Mugil curema populations in the Southeastern Caribbean Sea?
(Instituto Internacional de Ecologia, 2015-10)
The aim of the present study was to evaluate the potential use of otolith microchemistry (Sr:Ca and Ba:Ca ratios) to identify silver mullet, Mugil curema, populations in Southeastern Caribbean Sea. Fish samples were collected ...
Fish stocks of Urophycis Brasiliensis revealed by otolith fingerprint and shape in the southwestern Atlantic Ocean
(Academic Press Ltd - Elsevier Science Ltd, 2019-11-30)
Brazilian codling Urophycis brasiliensis is one of the main commercial coastal fish species from the Southwestern Atlantic Ocean. Regardless of its economic relevance, its stock structure remains largely unknown. In this ...
Spatial environmental variability of natural markers and habitat use of Cathorops spixii in a neotropical estuary from otolith chemistry
(Cambridge University Press, 2020-08-19)
The goal of this study was to study the distribution of potential habitat markers (Sr/Ca, Ba/Ca, Mn/Ca and Li/Ca) in water from the Paranaguá Estuarine Complex (Brazil) and to study habitat use patterns of Cathorops spixii ...
