Habitat residency and movement patterns of Centropomus parallelus juveniles in a subtropical estuarine complex

Abstract

Sixty Centropomus parallelus juveniles were collected in March 2013 in two locations (Tromomó and Guaraguaçu) inside the Paranaguá estuarine complex, southern Brazil. The habitat residency and movement patterns of the individuals were inferred from Sr:Ca ratios and age recorded in the otoliths. Data suggest that the species spawns preferentially in brackish areas mainly from October to January, and that growth rate during the early juvenile stage could be influenced by environmental salinity. Furthermore, the data also show that C. parallelus can occupy diverse salinity habitats and migrate among marine, brackish and freshwater areas within the Paranaguá estuarine complex, showing a high environmental plasticity and adaptation.

Reproductive biology of the tarpon snook Centropomus pectinatus (Perciformes, Centropomidae) in estuarine waters in the south‐western Atlantic

“…There is scant information on the biology of C. pectinatus. The main patterns that emerge from studies on Centropomus undecimalis (Bloch 1792) (McMichael et al, 1989;Taylor et al, 1998Taylor et al, , 2000Andrade et al, 2013), Centropomus medius Günther 1864 (Maldonado-Garcia et al, 2005), Centropomus ensiferus Poey 1860 (Aliaume et al, 1997(Aliaume et al, , 2005 and Centropomus parallelus Poey 1860 (Santos, 2014;Daros et al, 2016) are ones of complex and relatively similar life histories. They are estuarine dependent, euryhaline, diadromous, protandric hermaphrodites, with sex ratio changing by size, reaching sexual maturity as males at relatively small sizes (McMichael 687 et al, 1989;Taylor et al, 2000;Andrade et al, 2013).…”

“…They are opportunistic predators that feed on fish and decapods (Aliaume et al, 1997;Feltrin-Contente et al, 2009;Moreno-Sánchez et al, 2015). Although adults are common in freshwater (Stevens et al, 2007;Blewett et al, 2009;Daros et al, 2016), they migrate to high-salinity regions to spawn (Tucker & Campbell, 1988;Peters et al, 1998;Taylor et al, 1998;Alvarez-Lajonchère & Tsuzuki, 2008;Cerqueira & Tsuzuki, 2009).…”

Migration and brackish environment use of Prochilodus lineatus (Characiformes: Prochilodontidae) inferred by Sr:Ca ratio transects of otolith

“…In estuaries, salinity often has a positive correlation with otolith Sr:Ca when the freshwater end-member has lower Sr:Ca than sea-water (Secor, Rooker, 2000;Kraus, Secor, 2004;Martin et al, 2004;Sturrock et al, 2012). The techniques used to study ontogenetic changes of Sr:Ca ratio in otoliths include spot and line scan analysis by electron probe microanalysis (EPMA), microproton-induced X-ray emission (micro-PIXE) (Lin et al, 2007;Hedger et al, 2008;Daros et al, 2016), and more recently laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) (MoralesNin et al, 2014;Fowler et al, 2016;Kissinger et al, 2016;Avigliano et al, 2017b;Callicó Fortunato et al, 2017).…”

Using the same fish with different rules: A science‐based approach for improving management of recreational fisheries in a biodiversity hotspot of the Western South Atlantic

“…Other studies include the use of satellite telemetry to track billfishes, tunas, sharks and rays, increasing knowledge of pelagic species in other parts of the Brazilian coast and in areas close to oceanic islands of the Western South Atlantic (Afonso & Hazin, ; Mourato et al., ; Travassos, Pereira & Toloti, ). More recently, otolith chemistry began to be used for better understanding of fish movements in different environments along the Brazilian coast (e.g., Avigliano, Velasco & Volpedo, ; Daros, Spach & Correia, ). Nevertheless, this tool remains limited when a more refined understanding of habitat use by fish is still missing.…”
