Based on a model prediction, the distribution of S. The results also indicated the importance of the waters near the coast of northeastern Taiwan as a spawning ground. Complex and diverse distribution and movement patterns were observed in the three seasonal groups. lessoniana reflected the seasonal temperature fluctuation observed in Taiwanese waters, which indicated the reliability of the prediction method. The results showed that ontogenetic variation in the statolith δ 18O values in S. The probability of occurrence in a given area at each life stage in three seasonal groups was determined using salinity values, deduced and measured temperatures, and the known ecology of S.
lessoniana collected in northern Taiwan were analyzed to predict the experienced temperature history along with ontogenetic stages. The daily growth and δ 18O values from the core to the edge of statoliths of S. It is an important species in fisheries, but species management is difficult because of inadequate information regarding its life history. Sepioteuthis lessoniana is a widely distributed neritic squid in the Indo-Pacific Ocean. 5Department of Environmental Biology and Fisheries Science, National Taiwan Ocean University, Keelung, Taiwan.4Center of Excellence for the Oceans, National Taiwan Ocean University, Keelung, Taiwan.3Institute of Oceanography, National Taiwan University, Taipei, Taiwan.2Graduate School of Fisheries and Environmental Sciences, Nagasaki University, Nagasaki, Japan.1Institute of Marine Biology, National Taiwan Ocean University, Keelung, Taiwan.Chun-I Chiang 1,2, Ming-Tsung Chung 3, Jen-Chieh Shiao 3, Pei-Ling Wang 3, Tin-Yam Chan 1,4, Atsuko Yamaguchi 2 and Chia-Hui Wang 4,5*
