Strontium: calcium concentration ratios in otoliths of herring larvae as indicators of environmental histories

Determination of the strontium/calcium concentration ratios in otoliths of laboratory-reared herring larvae (Clupea harengus) showed that the deposition of strontium relative to calcium and the rearing temperature were related; ie Temperature (C) minus 2.955 strontium/calcium) times 1000 plus 19.172...

Description
Summary:Determination of the strontium/calcium concentration ratios in otoliths of laboratory-reared herring larvae (Clupea harengus) showed that the deposition of strontium relative to calcium and the rearing temperature were related; ie Temperature (C) minus 2.955 strontium/calcium) times 1000 plus 19.172. The degree of incorporation of strontium into the aragonite of herring otoliths was inversely related to temperature which was similar to findings for corals. The structure and chemical composition of herring otoliths could therefore provide detailed information on its temperature and environmental history. An example of the application of the technique to an approximately 6-month-old field caught herring larva is given. There are 45 references.
