Is it safe to eat fish from the Baltic Sea?
Fish from some areas of the Baltic Sea are so contaminated that they may be too toxic for EU markets, warns WWF. The level of brominated flame retardants (PBDEs) found in herring is 5 times higher in the Baltic Sea than in the Atlantic. But it is not only the fish that is contaminated.
Are there sharks in the Baltic Sea?
Contrary to popular belief, there are sharks in the Baltic Sea. In fact, 31 species of sharks and closely related skates, rays and chimaeras (collectively known as cartilaginous fishes) have been recorded in this area.
Is there salmon in Baltic Sea?
There are wild salmon rivers in all sub-basins of the Baltic.
What creatures are in the Baltic Sea?
Four marine mammal species are resident in the Baltic Sea: the grey seal, harbour seal, ringed seal and the harbour porpoise. These mobile top predators have an important role in regulating the food web, but are also sensitive to pressures in all their areas of distribution, as well as to changes in the food web.
Why can it be dangerous to eat a lot of fish from the Baltic Sea?
Despite the favourable nutritional qualities of fish, the consumption of salmon or trout and herring caught in the Baltic Sea, particularly in the Gulf of Bothnia and the Gulf of Finland, may subject consumers to higher than normal levels of dioxins and PCB compounds, which are harmful to health.
How dangerous is the Baltic Sea?
300,000 tons of munition are rotting away in the Baltic Sea, damaging fish and marine life and endangering people. Experts have investigated how dangerous the contaminated sites are and what should be done with them.
Why is the Baltic Sea a dead zone?
The Baltic Sea is no stranger to dead zones. The dead zones are due largely to the Baltic’s limited circulation and strong layering of water, which stop oxygen from replenishing bottom waters. Since the 1950s, nutrient pollution from fertilizer and sewage has caused hypoxia in the Baltic to surge.
Can you swim in Baltic Sea?
Sure you can. The water temperature in the Baltic Sea ranges from approximately 20 °C (68 °F) in the summer to 0 °C (32 °F) in the winter. Everybody can swim in 20 degree water. Many people swim in the sea even in the winter by making a hole in the ice covering the surface.
What is the Baltic Sea known for?
The Baltic Sea is a brackish inland sea, alleged to be the largest body of brackish water in the world (other possibilities include the Black Sea ). It is known that since 1720, the Baltic Sea has frozen over entirely a total of 20 times – the most recent case was in early 1987.
Do pike live in the Baltic Sea?
Baltic Sea populations of the northern pike (Esox lucius) have declined since the 1990s, and they face additional challenges due to ongoing climate change. Pike in the Baltic Sea spawn either in coastal bays or in freshwater streams and wetlands.
Is the Baltic sea salty?
The Baltic Sea is a large and almost entirely enclosed marine region, located far up in the cold north. It is a brackish sea with both salt and fresh water. The only connection with the ocean is through the Danish straits to the North Sea.
What countries are near the Baltic Sea?
The EU Member States – Denmark, Sweden, Finland, Estonia, Latvia, Lithuania, Poland and Germany – and Russia are all directly bordering the Baltic Sea. Parts of Norway and Belarus, both no riparian countries, are in the catchment area of the Baltic Sea.
Who is polluting the Baltic Sea?
The Baltic Sea is almost totally surrounded by land and therefore more endangered by pollution than other marine areas. The sources of marine pollution are municipal and industrial waste inputs directly into the sea or via rivers, and atmospheric inputs mainly from traffic and agriculture.
Who owns the Baltic Sea?
The Baltic Sea is an arm of the Atlantic Ocean, enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude.
Is Baltic Sea a lake?
The Baltic Ice Lake is a name given by geologists to a freshwater lake that evolved in the Baltic Sea basin as glaciers retreated from that region at the end of the last ice age. The Baltic Ice Lake is one of a number of water stages that eventually resulted in the modern Baltic Sea.
