Abstract
Abstract Seventy-one Sardinella zunasi individuals collected from 5 locations in the Northwest Pacific were used in an AFLP analysis to examine the population genetic structure of S. zunasi . Using 4 selective primer combinations, 414 putative loci were detected, including 340 polymorphic loci (82.13%). Both AMOVA and pairwise F ST analysis detected significant population genetic structure between Chinese and Japanese populations, supporting separate stocks in this species. The UPGMA trees also detected significant spatial structure within S. zunasi . Pleistocene glaciations are hypothesized to be responsible for the genetic differentiation. The significant genetic differentiation found among S. zunasi populations might also be due to geographic isolation, because a pattern of isolation-by-distance was observed. The weaker but significant structures between the Japanese Aichi and Kagawa populations might be impacted by the semi-enclosed coastal topography there. No significant genetic structure was detected among the Chinese populations, perhaps because of S. zunasi ’s migratory behavior and ocean current patterns.
