closure. Not until about halfa century ago
were hatcheries built which were operated
over longer periods of time. Thus a hatch-
ery built in 1922 at the farm Alvidra near
the river Sog was in operation for about
four decades. In 1932 the Reykjavík
Municipal Hydro-Electric Power Com-
pany established a hatchery at the river
Ellidaár with a capacity of hatching 1.2
million salmon ova. This hatchery has
been operated ever since.
Rearing stations
The first attempt at rearing salmonid fish,
i.e. sea trout, was made in northeastern
Iceland during the years of the second
world war, but was discontinued. The
rearing of salmon fry was first tried in 1944
in the district of Borgaríjördur and 3 years
later in the district ofÁrnessýsla; but these
attempts also came to an early end. In
1952, however, outdoor rearing of salmon
fry was added to the hatching activities of
the municipal authorities at the Ellidaár,
for production of 1-summer-old finger-
lings to be released in rivers. This work
was extended by the building of indoor
rearing facilities in 1964.
1961 the Government of Iceland com-
menced building the Kollafjördur Ex-
perimental Fish Farm near Reykjavík
with a twofold purpose: To experiment
with hatching and rearing of salmonids to
the smolt size and even beyond that when
considered expedient, and to produce
salmonids to various sizes for sale, to be
released in rivers and lakes to improve
fishing. Special emphasis was placed on
