Hatcheries have long produced salmonids for fisheries and mitigation, though their
widespread use is increasingly controversial because of potential impacts to wild salmonids …

Abstract The Baltic Sea has a rare type of brackish water environment which harbours
unique genetic lineages of many species. The area is highly influenced by anthropogenic …

Abstract The longest Baltic River, the Vistula, historically hosted numerous sea trout
populations. However, dam construction in the twentieth century drastically reduced the …

Selection, genetic drift, and gene flow affect genetic variation within populations and genetic
differences among populations. Both drift and selection tend to decrease variation within …

The genetic structure of a fish population is usually thought to be stable over time. In the
southern Baltic, Salmo trutta m. trutta (sea trout) populations have been characterized by low …

The impacts and interactions between hatchery-bred fish and wild fish populations has been
a topic of active investigation in recent decades. In some instances, the benefits of stocking …

Several rivers that are tributaries of the Oder estuary are inhabited by Salmo trutta L, the
most important of which are Ina, Gowienica, and Wołczenica. Both forms of the species, sea …

Brown trout (Salmo trutta L.) is an important resource both for conservation and recreational
fisheries in Iberian Peninsula, but the species is threatened in Llobregat River, an important …

Each year, millions of hatchery‐reared sea‐run brown trout Salmo trutta L.(the sea trout)
juveniles are released into the natural environment in the Atlantic region. The aim of this …

Abstract The Vistula River, rich with sea trout (Salmo trutta m. trutta L.) is the longest river in
Poland, flowing into the southern Baltic Sea, with its population sustained mainly by …
