(Coregonus lavaretus) and grayling, while in the lower-lying lakes the
vendace-(Coregonus albula) is of paramount importance. All the species of fish
mentioned, with the exception of the charr, are also found in the Baltic; the
grayling, however, is caught only in the northern part of the Gulf of Bothnia.
The crayfish-fishery, too, in Southern and Central Sweden, is of no little
importance. In 1907, however, the so-called "crayfish disease" broke out in
Lake-Mälaren, with the result that it has exterminated the crayfish in that lake, in
Lake Hjälmaren, and in a number of streams and lakes communicating with
the waters mentioned.
In general, the lake fisheries of Sweden have not been managed or utilized in
a rational manner, but still they have been fairly productive (see above).
The-average annual yield of the Swedish fresh-water fisheries has been calculated as
being no more than about 3 kilograms of fish per hectare, while average
lakes in the north of Germany yield 15—30 kilograms. One chief reason
of the poor yield of the lake-fishery in Sweden is, that it is carried on and
managed in an unsatisfactory manner, for the number of owners of the fishing
rights is so great that it is impossible to carry on the fishing in
accordance-with a uniform and properly organized plan.
Fish Culture.
Sweden is, as far as is known, the first country in Europe where
attempts were made to assist the spawning of the common inland lake fish
by means of special contrivances, for the purpose of improving the
fishing. As early as 1761, the Mayor of Linköping, K. F. Lund,
published in the "Proceedings of the Royal Academy of Sciences" an essay
called "On the Planting of Fish in Inland Lakes", where he gave an
account of a method for hatching out perch and other inland lake fish (not
salmon idæ) in pens lined with brush. His attemps were afterwards
forgotten until about 1850, when attempts at fish-culture were again begun,,
and it was not until 1865 that a complete institution for
salmon-cultivation was established at the expense of the State, whose "normal
institution" afterwards became a pattern for a large number of such
institutions throughout the country, of which there are now between thirty
and forty.
Fish culture in ponds was carried on in ancient times at the monasteries and
on many large estates, especially in Skåne, where the carp was introduced from
Denmark at the beginning of the sixteenth century, but these ponds were
afterwards neglected. The culture of carp has been recommenced of låte years,
and in Gustavsborg in Skåne there is a large number of carp-ponds on
the-German model, built in 1879. From these ponds about 20 000 kronors’ worth
of carp was sold as early as in 1896, principally to Germany. The carp,
however, thrive as far to the north as Värmland, where experimental
carp-breeding-ponds were laid down at the Långbanshytt-an estate; it appears, however, that
carp-culture cannot be carried on so far to the north to much advantage. In.
the highlands of Småland and north of them, the tench can probably occupy
the same position in regard to fish-culture in ponds as that taken by the
carp-in the southernmost parts of the country. The culture of both these species
of fish has received a great impulse since the formation, in 1906, of the
fisheries association called the "Södra Sveriges Fiskeriförening". The most impor-
