Seal and ringed seal population growth in the Baltic sea – ringed amounts vary April were jäätilan you with

This year in the Baltic sea has been seen over 38 000 grey seal, i.e. hall, told the Natural resources institute finland Luke (you move to another service) today, Tuesday. In earlier censuses to see the hall, the figure has remained in approximately 30 000 individuals in the. These Finnish sea area was, however, only 14 of 200 individuals.

Halls appears in the outer islets between may and June, when they have hair changing going on. In this case, the majority of them can be described of flight calculation in the. In finland, the species shown in this case, mostly south-west Finland to the foreign islets, as well as Central Sweden and Western Estonia waters.

the Baltic sea garage stock has increased by an average of about five percent per year since the early 2000s. Growth has in recent years been strongest in the southern Baltic sea, mainly due to other areas of the transferred pools. Population growth is explained not only by real growth, also last spring in good counting conditions have.

icy conditions cause ringed fluctuations

This year the ringed seal balance was 12 800 individuals of bothnia, while last year they were detected significantly less (about 9 900). On the other hand, two years ago, in 2017 individuals were observed in 13 of 600 pieces.

the Largest variations are not luke's, due to sudden changes in position, but in the time of change of circumstances. It's April, since ice conditions, which have fluctuated strongly over the last six years, Luke told me. If ice breakage has started already before the calculation begins, seen in the larger ringed groups. In this case, the ringed seal appears significantly more than the years, that you have yet to break.

Tad growth has also been in the freshwater a rare our, after the ice age, stranded ice the saimaa ringed seal situation. Now though let's talk just a couple of dozens of individuals and hundreds or thousands, such as the Baltic seals on it.

This year lake Saimaa was born 88 baby seals and all the ringed seal of Saimaa is 410 forest the government's latest estimates. The saimaa ringed seal is still highly endangered. In the previous assessment in reading was estimated to be 380-400.
