SUMMARY
The Isopod Synidotea bicuspida
(Owen) found in Icelandic
waters
by Jörundur Svavarsson,
Institute of Biology, Universily of lceland,
Grensásvegur 12, Reykjavík.
Synidotea bicusþida (Owen 1839) is recorded
for the first time from Icelandic waters.
Three specimens and a fragment were
collected from the trawl of the. research
vessel Bjarni Sæmundsson on 22 November
1978 at 66°17’N and 23°36’W from depths
of 70—105 meters. Near bottom
temperature and salinity measured close to
this locality (66°16’N — 23°20’W) on 13
November 1978 were 6.8°C and 34.8%o.
This record links populations of S. bicusþida
(sensu Menzies and Miller (1972)) at
Spitzbergen and in the Barent Sea with
those found at Labrador and in the St.
Lawrence area. It is suggested from
consideration of oceanic current systems
that the origin of the Icelandic population
lies in the Spitzbergen area and the
apparently isolated population in eastern
North America may also have a similar
origin.
