Low levels of genetic structuring in King George whiting Sillaginodes punctatus across two geographic regions

J Fish Biol. 2018 Feb;92(2):523-531. doi: 10.1111/jfb.13510. Epub 2017 Dec 7.

Abstract

Postlarvae of King George whiting Sillaginodes punctatus, a commercially important fish species in southern Australia, were collected from multiple locations across south and south-eastern Australia. Genetic analyses using seven microsatellite markers found little evidence of genetic structure suggesting high levels of connectivity between the regions. The results found no evidence of a distinct source spawning population within the south-eastern range sampled in this study.

Keywords: Sillaginodes punctatus; connectivity; fisheries management; microsatellite markers; population structure.
