Data from: Oceanographic connectivity and environmental correlates of genetic structuring in Atlantic herring in the Baltic Sea
Marine fish often show little genetic structuring in neutral marker genes, and Atlantic herring (Clupea harengus) in the Baltic Sea are no exception; historically, very low levels of population differentiation (FST ≈ 0.002) have been found, despite a high degree of interpopulation environmental heterogeneity in salinity and temperature. Recent exome sequencing and SNP studies have however shown that many loci are under selection in this system. Here, we combined population genetic analyses of a large number of transcriptome-derived microsatellite markers with oceanographic modelling to investigate genetic differentiation and connectivity in Atlantic herring at a relatively fine scale within the Baltic Sea. We found evidence for weak but robust and significant genetic structuring (FST = 0.008) explainable by oceanographic connectivity. Genetic differentiation was also associated with site differences in temperature and salinity, with the result driven by the locus Her14 which appears to be under directional selection (FST = 0.08). The results show that Baltic herring are genetically structured within the Baltic Sea, and highlight the role of oceanography and environmental factors in explaining this structuring. The results also have implications for the management of herring fisheries, the most economically important fishery in the Baltic Sea, suggesting that the current fisheries management units may be in need of revision.
Data from: Echinorhynchus salmonis Müller, 1784 (Acanthocephala: Echinorhynchidae) from the Bothnian Bay, Baltic Sea: morphological variability and radial asymmetry of proboscis hooks
Echinorhynchus salmonis is a common parasite of salmoniform and other fishes, occurring in fresh and brackish waters throughout the Holarctic. Presented here is the first analysis of the morphometric and meristic variation in a Palaearctic population of E. salmonis, collected from whitefish Coregonus lavaretus L. and smelt Osmerus eperlaus (L.) from the Bothnian Bay, northern Baltic Sea. Morphological data were compared with published descriptions of congeneric taxa. Nearctic populations of salmonid echinorhynchids considered by some to represent a distinct species, E. coregoni Linkins in Van Cleave, 1919, did not show any morphological divergence from Palaearctic populations, indicating that the name E. coregoni should be suppressed. Similarly, E. alpinus Linstow, 1901 has been considered to be a junior synonym of E. salmonis. However, E. alpinus should be regarded as a valid species, because it has a longer and more elongate body. The armature of the acanthocephalan proboscis typically displays radial symmetry. However, in E. salmonis the hooks on the dorsal surface of the proboscis are smaller than those on the ventral surface. Size differences between dorsal and ventral hooks are most pronounced at the base of the proboscis. The systematic and functional significance of radial asymmetry of proboscis hooks is discussed.
