Polymorphic microsatellite markers for stock identification in Japanese anchovy (Engraulis japonica)

Japanese anchovy (Engraulis japonica) is a migratory marine fish of high economic significance in Taiwan. The adult Japanese anchovies migrate from the East China sea to spawn in coastal waters of Taiwan; the larvae then drift back to the East China Sea to complete their life cycle. We developed six highly polymorphic microsatellites for E. Japonica (expected heterozygosity ranging from 0.751 to 0.971) and these microsatellites can be used as genetic markers for identifying stocks to establish regulations in fishing management. Moreover, the markers will be useful in inferring the stock origins and migration routes in the future.
