  abstract = {{O}tolith elemental signatures can be used to identify when individual or groups of fish are spending a significant amount of time in different environments. {E}lemental signatures of juvenile sardine {S}ardinops sagax caught in winter 2008 and 2009 around the coast of {S}outh {A}frica were measured using inductively-coupled plasma mass-spectroscopy. {T}he otolith elemental signatures of 34 fish caught in 2008 and of 52 fish caught in 2009 were measured at the edge (to represent conditions 20-30 days prior to capture). {P}rincipal component analysis was used to visualise the relationships of individuals to each other, in terms of their otolith chemistry, in two-dimensional space, and multiple {ANOVA}s were used to investigate spatial and temporal variations among samples collected in 2008 and 2009. {S}ignificant differences among sites were found in {MANOVA}s, but the between-site differences varied among the elements. {M}agnesium concentration tended to decrease whereas barium concentration tended to increase from the west to the east coast. {B}arium indicate upwelling impact but for 2008 samples on the northern part of the west coast. {O}tolith microchemistry provides evidence of large and small-scale differentiation in sardine, but differences between years indicates that this is not necessarily temporally stable. {T}he ocean off {S}outh {A}frica is a dynamic and variable environment and this is reflected in the inter-site, and also inter-annual, differences in elemental signatures of juvenile sardine.},
