Inter-Annual variability in otolith chemistry of catfish Genidens barbus from South-western Atlantic estuaries [PDF]
, 2017 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, Sr:Ca and Zn:Ca ratios) for ...

Analysis of the 90º and 150º angles for increment counting in otoliths of estuarine catfish
Ocean and Coastal ResearchFish age can be estimated with the use of age rings in calcified structures, such as otoliths. However, it is important to select an appropriate axis for counting the number of increments and to confirm that the age rings are visible in the otolith and ...

Diel variation in fish assemblages in tidal creeks in southern Brazil
Brazilian Journal of BiologyTidal creeks are strongly influenced by tides and are therefore exposed to large differences in salinity and depth daily. Here we compare fish assemblages in tidal creeks between day and night in two tidal creeks in southern Brazil. Monthly day and night,
