SUMMARY
Aerial census of
Common Seal
(Phoca vitulina L.
at the coast of Iceland
in 1980
by
Erlingur Hauksson
Icelandic Fisheries Laboratories
Skúlagata 4
Reykjavík
In the period 11-22 August 1980, an
aerial survey for assessment of the num-
bers of common seals on the Icelandic
coast was carried out.
Common seals were most numerous at
the south, west and northwest coasts (fig.
1) . A total of about 15 thousand animals
were seen. Corrected for undersampling,
this amounts to about 21 thousand animals
on the shore at the time of counting (table
2) . By taking this number as an index of
the population size, and assuming that the
true density of the population is 2.1 times
this index, the number of contmon seals at
the coast of Iceland, would be at least 30
thousand.
