Different element/Ca ratios in the otolith of cultured sea bass in Malaysia and relationship to salinity

The otoliths of cultured sea bass (Lates calcarifer) were sampled from 24 locations in Malaysian coastal waters in order to analyse the ratio values of Sr/Ca, Mg/Ca, Ba/Ca and Zn/Ca. Then the ratio values were discriminated to reconstruct a reliable marker for the migration of wild sea bass. Culture...
