摘要

Tract elements in the squid statoliths were analyzed by jPIXE for following seven species distributing at offhsore and inshore waters: Family Ommastrephidae, Ommastrephes bartrami, Todarodes pacificus; family ALoliginidae, Loligo bleekeri, L duvaucelii L. chinenesis, L. edulis and Sepioteuthis lessoniana. Statoliths of all seven species contained managese, iron, capper, zinc and relatively high amount tof strontium. Statoliths Sr concentration, an possible index for thermal history of the animal's habitat, were the highest in O. bartrami that spends their entire life time at pelagic water, and secondly highest in T. pacificus living at the pelagic as well as the coastal waters. On the other hand, statoliths Sr concentration was relatively low in the five species of Loliginidae living at coastal waters, with following order: L. edulis >S. lessoniana>L. duvaucelii >L. bleekeri>L. chinensis. These observations may indicate that quantity of the statoliths trace elements are species specific in squids, thus would be a possible "key" to reconsidering about taxonomy and distribution in squid.
