Abstract

The potential use of Sr/Ca and Ba/Ca ratios in fish otolith, as a complement to 87Sr/86Sr to study movements of Prochilodus lineatus, was evaluated in the La Plata Basin (South America). Water ratios were obtained from samples collected during the high and low water seasons at 42 sites across the La Plata Basin. Elemental and isotopic ratios in water were measured by MC-ICP-MS, ICP-MS and ion chromatography, and obtained from available literature. Fish were caught from six different sites with different physiochemical features. Otolith core-to-edge Sr/Ca and Ba/Ca profiles were determined by LA-ICP-MS, while the otolith 87Sr/86Sr data set was taken from literature. The predictive classification by rivers according to water Sr/Ca, Ba/Ca and 87Sr/86Sr ratios (92.5%) was higher than that based solely on 87Sr/86Sr (58%), with classification that reached 100% for several rivers. Unlike Ba/Ca, a significant relationship (R2 = 0.94, p < 0.05) was found between otolith edge and water Sr/Ca, suggesting that this could be an efficient movement indicator for P. lineatus. The Sr/Ca ratio complemented the information provided by Sr isotopes and it was particularly useful in the northwest basin, where the isotopes alone do not allow differentiating between large rivers.

Ethics declarations

The authors declare not to have any interest conflicts. Prochilodus lineatus is not protected under wildlife conservation laws (local legislations, IUCN, or CITES). As the Consejo Nacional de Investigaciones Cientificas y Técnicas (CONICET) does not possess a formal animal research ethics committee regarding the fish welfare and sampling protocols, fish handling during sampling was performed following guidelines of the ethical committee of the UFAW Handbook on the Care and Management of Laboratory Animals (http://www.ufaw.org.uk). Collection fish was authorized by the local Wildlife and Fisheries Authority guidelines and policies (Ministerio de Ecología y Recursos Renovables of Misiones Province, Law XVI N° 47, N° 509/07 and 052/18, Dirección de Recursos Naturales of Corrientes Province, Law 1863/54, and Comisión Administradora del Río Uruguay, RS27/04). The fish in this study were not a part of faunal surveys and they did not employ any type of experimental procedure, surgery or chemical agents that would induce injury on the collected organisms.
