Compositions of the trace elements in bivalve shells and fish otoliths, both of which are made of calcium carbonate crystals, largely reflect those of elements in the environment, and thus, may be “foot prints” of the individuals’ environmental life histories. In the present study, the trace elemental compositions of these tissues were applied to the discrimination of production places of the aquacultured scallop Patinopecten yessoensis and rainbow trout Oncorhynchus mykiss. Concentrations of lithium, manganese, strontium and barium in the aquacultured, 2+-year old scallop shells, which were from Otsuchi and Yamada in Iwate prefecture and Shikabe and Shiriuchi in Hokkaido, were measured by inductively coupled plasma mass spectrometry. By MANOVA analysis, the discrimination accuracy was 81.3%; 9 individuals, mostly from Otsuchi, out of 48 ones were mis-discriminated. Similarly, elemental concentrations of the otoliths from Hachimantai in Iwate and Nanae in Hokkaido were quantified. The discrimination accuracy by MANOVA was 95.5%; two individuals out of 44 ones were mis-discriminated. These data suggest that elemental compositions of bivalve shells and fish otoliths are useful keys to estimate their origins in the aquacultured species, although variations of the compositions by the production year should be carefully studied further.
