Unraveling adaptive genetic variation represents, in addition to the
estimate of population demographic parameters, a cornerstone for the
management of aquatic natural living resources, which in turn, represent
the raw material for breeding programs. The turbot (Scophthalmus maximus)
is a marine flatfish of high commercial value living on the European
continental shelf. While wild populations are declining, aquaculture is
flourishing in Southern Europe. We evaluated the genetic structure of
turbot throughout its natural distribution range (672 individuals; 20
populations) by analyzing allele frequency data from 755 Single Nucleotide
Polymorphism discovered and genotyped by Double Digest RAD Sequencing. The
species was structured into four main regions: Baltic Sea, Atlantic Ocean,
Adriatic Sea and Black Sea, with subtle differentiation apparent at the
distribution margins of the Atlantic region. Genetic diversity and
effective population size estimates were highest in the Atlantic
populations, the area of greatest occurrence, while turbot from other
regions showed lower levels, reflecting geographical isolation and reduced
abundance. Divergent selection was detected within and between the
Atlantic Ocean and Baltic Sea regions, and also when comparing these two
regions with the Black Sea. Evidence of parallel evolution was detected
between the two low salinity regions, the Baltic and Black seas.
Correlation between genetic and environmental variation indicated that
temperature and salinity were probably the main environmental drivers of
selection. Mining around the four genomic regions consistently inferred to
be under selection identified candidate genes related to osmoregulation,
growth and resistance to diseases. The new insights are useful for the
management of turbot fisheries and aquaculture by providing the baseline
for evaluating the consequences of turbot releases from restocking and
farming.
