FISHING EFFORT
For more than 85 years the Ellidaár has
been operated primarily as a sports-fish-
ing stream. Only in the early years of this
time period were salmon caught and sold
commercially from seining operations in
the lower reaches. The effort expended for
the time period is listed in Table 1. Over
the years there has been an increase in
eífort from the original two rods to six rods
of recent years. This must be seen in rela-
tion lo the total catches made each year,
hatchery operations and releases of
juvenile salmon of various ages, and the
opening of the dam at Ellidavatn which
provided new spawning and rearing
areas.
YIELDS AND MANAGEMENT OF
THE ELLIDAÁR
The history of the river is divisible into
four well-defined periods. A pre-
documentary period covers the years of
exploitation prior to 1925. Some catch re-
cords of this era do exist (Tabble 2); how-
ever they are sporadically kept and open
