recorded from the Faroese Fishery Territory: with life
style category; depth range ofrecords (* indicate that
specimens may have been caught in the water
column); number ofrecords in the depth zones 0-299
m, 300-999 m and > 1000 mfor the years prior to
1987 and after 1987; the water mass(-esjfrom which
the species were collected (AW = Atlantic Water; AI =
Arctic Intermediate Water; NW = bottom water ofthe
Norwegian Sea); and measured and estimated
temperature range.

the hyperbenthic species Pandalus mon-
tagui (> 120 records), Eualus pUsiolus (>
97), Pandalus propinquus (> 81), Sabinea
sarsii (79), Dichelopandalus bonnieri (73),
and Pontophilus norvegicus (73). The dom-
inant species in the phytal zone are Eualus
pusiolus, Hippolyte varians, and juveniles
of Lebbeus polaris and Pandalus montagui
(see also Berggren, 1994). Species that
were only recorded once were the meso- to
bathypelagic species Systellaspis debilis,
and the hyperbenthic species Caridion
steveni and Philocheras fasciatus.
A summary of the records of the species
is given in Table 1.
The Faroese fauna of Decapoda Natantia
consists of 25 hyper- and epibenthic
species, 5 benthopelagic species, and 5
meso- and bathypelagic species. The latter
are confíned to slope waters (300-999 m) or
the deep sea (> 1000 m). Four of the ben-
thopelagic species are recorded most often
from slope waters and one species (Bytho-
caris leucopis) exclusively from cold, deep
water. Sixteen of the hyper- and epibenthic
species are most often recorded from the
Faroe plateau or the top of the banks (0-299
m), 3 species seem to be shelf and slope
species, and 6 species seem to be slope
species.
Twenty-four species are mostly confíned
to »warm« AW, 5 species are mostly from
cool AI, 4 species are mostly from cold
NW, and 2 species are recorded from two or
three different water masses.
Together with up-coming results on the
Icelandic Decapoda Natantia fauna collect-
ed during the BIOICE programme (1991-)
the improved knowledge of the fauna of
shrimps and prawns in the Faroe area will
provide a new platform for studies of distri-
butions of natant decapod species in the
transition area between the North Atlantic
and the Norwegian Sea.
