Hard tissues such as fish scale and otoliths are continuouslydeposited from fish birth to its death. Therefore hard tissues are recording information that fish experienced. In order to investigate the infomation, scale circuli and trace elements in otoliths of red sea bream, Pagrus major, were analyzed. Scale circuli werecountedto investigate a relationbetween circuli deposition and temperature. Trace element concentration were analyzed by Particle Induce X-ray Emission (PDOE). These studies showed that there were some relations betweenhard tissuesformation and ambientseawatertemperatures.
