Can trace element signatures in the otoliths of Dissostichus eleginoides record capture size?
Abstract: The elemental structure of growth increments in the otoliths of fish reflects the ... composition of water passing across the gills: as a result, elemental signatures can potentially be used to ... reconstruct the environmental history experienced by fish.
