Population structure and natal origins of European hake were investigated using
microsatellite DNA markers and otolith geochemistry data. Five microsatellites were
sequenced and otolith core geochemical composition was determined from age-1 hake
collected in the northeast Atlantic Ocean and the Mediterranean Sea. Microsatellites
provided evidence of a major genetic split in the vicinity of the Strait of Gibraltar,
separating the Atlantic and the Mediterranean populations, with the exception of the Gulf
of Cádiz. Based on classification models using otolith core geochemical values
individuals’ natal origins were identified, although with an increased error rate. Coupling
genotype and otolith data increased classification accuracy of individuals to their potential
natal origins while providing evidence of movement between the northern and southern
stock units in the Atlantic Ocean. Information obtained by the two natural markers on
population structure of European hake was complementary as the two markers act at
different spatio-temporal scales. Otolith geochemistry provides information over an
ecological time frame and on a fine spatial scale, while microsatellite DNA markers report
on gene flow over evolutionary time scales and therefore act on a broader spatio-temporal
resolution. Thus, this study confirmed the usefulness of otolith geochemistry to
complement the assessment of early life stage dispersal in populations with high gene flow
and low genetic divergence.

Kin and population recognition in sympatric Lake Constance perch (Perca fluviatilis L.) : can assortative shoaling drive population divergence?
Behrmann-Godel, Jasminca; Gerlach, Gabriele; Eckmann, Reiner (2005-08-02)Prior studies have shown that perch (Perca fluviatilis L.) of Lake Constance belong to two genetically different but sympatric populations, and that local aggregations of juveniles and adults contain closely related kin. ... -
Elemental signatures in otoliths of larval walleye pollock (Theragra chalcogramma) from the northeast Pacific Ocean
FitzGerald, Jennifer L.; Thorrold, Simon R.; Bailey, Kevin M.; Brown, Annette L.; Severin, Kenneth P. (U.S. Department of Commerce, 2004)The objectives of this study are to determine if larval walleye pollock from different geographic localities can be distinguished based on elemental signatures in their otoliths. By analyzing sagittal otoliths with both ... -
