“…4). Although there is a known positive correlation of Sr:Ca with salinity and Ba:Ca with freshwater (Elsdon & Gillanders 2005, Sturrock et al 2012, Reis-Santos et al 2013b, the mean concentrations of both element:Ca ratios in the otolith edge were not significantly different be tween individuals of the same year class caught in the neritic and littoral zones (Mann-Whitney U = 290 and p > 0.05 for Sr:Ca; U = 268, p > 0.05 for Ba:Ca). We hypothesize that the salinity difference, as well as the freshwater input, was not large en ough in this case to produce distinct otolith chemical signatures between the 2 sampled habitats, hindering our ability to use otolith chemistry to dis entangle movements between these 2 proximate coastal marine areas (as poin ted out by Albuquerque et al 2012 for Sr:Ca and salinity ranges of these areas).…”

“…This fundamental aspect of fish life history can be revealed through the evaluation of natural markers such as otolith microchemistry (Rooker et al 2008, Reis-Santos et al 2013a, Darnaude et al 2014, as detailed analysis of the chemical composition of otoliths allows reconstruction of the environmental conditions experienced by individual fish throughout their entire life history (Campana 1999, Elsdon et al 2008, Tanner et al 2013. In general, strontium (Sr) and barium (Ba) concentrations in otoliths have a positive correlation with salinity and freshwater, respectively (Elsdon & Gillanders 2005, Sturrock et al 2012, Reis-Santos et al 2013b). Thus, fish living in marine waters present higher otolith strontium concentrations compared to fish living in freshwater, whereas the latter present conspicuously higher otolith Ba concentrations than fish living in marine waters.…”

Otolith microchemistry (Sr:Ca, Ba:Ca) was used to evaluate habitat use patterns of the endangered dusky grouper Epinephelus marginatus in southern Brazil. Individual Sr:Ca profiles exhibited low variation, with an overall tendency to increase with age. Interestingly, individual Ba:Ca profiles presented 3 contrasting patterns: the first comprised most sampled individuals (> 80%), mostly indicative of the predominant use of marine waters throughout their life history; the second pattern (~10% of all individuals) indicated that dusky grouper may use or remain in or near estuarine waters for short time periods; finally, the third identified pattern (~5%) comprised individuals remaining in estuarine waters for long periods and provided the first evidence for this species of prolonged estuarine habitat use (over a year), in particular during juvenile life stages.

“…Laboratory experiments in Chinook salmon Oncorhynchus tshawytscha have suggested that Ba/Ca may show complex interactions between temperature, salinity and growth (Miller, 2011). Reis-Santos et al (2013) also accept that temperature and salinity affects the incorporation of Ba in sea bass, but other studies show that Ba/Ca is rather insensitive to temperature and salinity and depends on ambient Ba concentrations (Webb et al, 2012). In general, there is a tendency to attribute a negative correlation between salinity and Ba, and a positive correlation between productivity and Ba.…”

Daily otolith growth and ontogenetic geochemical signatures of age-0 anchovy (Engraulis encrasicolus) in the Gulf of Cádiz (SW Spain).

The European anchovy fishery in the Gulf of Cádiz (ICES Division IXa South) is largely influenced by age-0 individuals. Knowledge of young-of-the-year-growth dynamics is crucial for management, yet data on daily growth are lacking in the area. Linking growth patterns to the environment requires information on habitat occupancy through ontogeny of the fish that reach the fishery, as anchovy use different areas of the Gulf and the Guadalquivir Estuary throughout development. We describe the growth dynamics of age-0 anchovy through otolith microstructure analysis, and couple these data with data on microchemical signals in the otoliths to shed light into habitat use and growth dynamics in the area. Age-0 anchovy captured in September 2011 in the Gulf ranged from 3 to 6 months old for similar sizes, with average growth rates varying twofold. Individual non-linear growth curves showed that maximum otolith growth was positively correlated with the date of spawing. There was no correlation between growth parameters and body length or condition (Fulton K) at capture. The strontium:calcium (Sr/Ca) and magnesium:calcium (Mg/Ca) ratios were significantly lower at the edge of the otolith (approximately the age of capture) than at ages corresponding to larval and early juveniles (<60 days old), but values fell within typical estuarine-dwelling species values. The barium:calcium ratio (Ba/Ca) increased significantly at the edge of the otolith, which possibly resulted from residing in highly productive coastal waters or from ontogenetic effects. The variance in otolith elemental ratios was larger at otolith back-calculated ages around 50 days old, an age that coincides with the presumed closer dependence of estuarine waters. Our data are a first step towards understanding the contribution of the estuarine system to the anchovy fishery in the Gulf. The limitations of the approach and future steps are discussed.

“…Tabouret et al, 2010;Santos et al, 2013), a coefficient of 1 represents elemental deposition into the otolith in equal proportion as the environment concentrations, while values lower than 1 represent elemental discrimination, and values higher than 1 represent active elemental uptake Gillanders, 2003, 2005). Except for La Guardia (D Sr =0.81), all partition coefficients were close to 1 (D Sr =0.92-1.10), showing that Sr:Ca ratios of otoliths were similar as ratios from surrounding water.…”

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 in 7 areas of Nueva Esparta State (Venezuela). The otolith Sr:Ca and Ba:Ca ratios and water Sr:Ca were determined (by ICP-OES and EDTA volumetric method). Otoliths Sr:Ca and Ba:Ca ratios and Sr:Ca partition coefficient of mullets in Cubagua island (south of the State) were significantly different from ratios in La Guardia (north of the State). A discriminant analysis of otolith Sr:Ca and Ba:Ca ratios separated Cubagua Island from La Guardia values. These results suggest the existence of different mullet groups in the Southeastern Caribbean Sea. For this, the simultaneous use of Sr:Ca and Ba:Ca ratios could be a potential tool to identify populations in the study area.Keywords: Mugilidae, fish resource, otolith, microchemistry.
