FAUNA.
81
The water of the Baltic, which was a lake in early times, has a
comparatively small percentage of salt. The natural consequence is that only
very few marine forms have been able to immigrate, so that its fauna may
be said to be poor in species. In its islet-waters, howeever, there live a
•certain number of fresh water fishes. In the southern part, where the
water is a little more brackish, there are also a number of real sea-fishes,
of which the codfish (Gadus callarias) comes even far up inte the Gulf of
Bothnia. The variety of herring (Clupea harengus) known bj’ the name
of Strömming and distributed also over the Gulf of Bothnia, is
incomparably the most important product of the fishing industry in the Baltic.
Here, a small whale, the common porpoise (Phocoena communis), also at
"times roams as far as north of the sea of Åland. Among invertebrate
animals there are, with the exception of entomostracans, but few forms in
the Baltic and its bays. Towards the Sound the fauna grows richer; and
on the western coast of Sweden, in the Kattegat and the Skagerack, we
find a fully developed marine fauna.
