Urtak

I 1987 varð farið at kanna sjó- og botndjóralívið í

føroyskum sjógvi sum eitt norðurlandskt tiltak undir

heitinum BIOFAR. Høvuðsdentur varð lagdur á at savna

tilfar á meira enn 100 metra dýpi. Tá ið savníngin í 1993

var liðug varð farið undir nýggja verkætlan í 1995

BIOFAR 2, sum fevndi um savning úr fjøruni og út á

100 metra dýpi.

Tað vóru bara 16 sløg av mysidum skrásettar í før-

oyskum sjógvi undan BIOFAR. Við BIOFAR kom talið

uppá 34. Um hvørt skrásett slag er henda upplýsing:

Navnið saman við navninum á tí, sum hevur skrivað

frágreingina og árið, hetta er almannakunngjørt, sam-

heiti, vísa til rit við góðari lýsing, eldri føroyskar skrá-

setingar, Biofar støðir har sløgini eru funnin, frásøgn um

leið, dýpið, máldur ella mettur hiti í sjónum niður at

otni, slag av sjógvi har dýrið varð tikið og ein stutt

frágreiðing um útbreiðslu og dýpið í Atlantarhavinum

har hetta slagið livir.

27 sløg hava hyperbentiskan lívshátt, 5 eru meso-

ella bathypelagisk. 6 sløg eru oftast skrásett á føroyska

landgrunninum ella bankunum (0-299 m), 16-18 sløg

tykjast at liva í hellingini (300-999 m) og 10-12 sløg eru

vanliga tikin á djúpum vatni (> 1000 m). 18 sløg eru van-

liga í sjógvi, nevndur »heitur« Atlants sjógvur (>7°C)

ella í Ishavninum (1,5-3,5°C) og 9 sløg eru oftast at

finna í væl blandaðum sjógvi.

Abstract

Investigations on the marine benthic fauna of the Faroe

Fishery Territory started in 1987 as a Nordic programme

called BIOFAR with sampling efforts concentrated on

depths deeper than 100 m. After'the BIOFAR samplíng

was concluded in 1993, a new programme called BIO-

FAR 2 started in 1995 to sample the marine benthic fau-

na from the intertidal to 100 m depth.

Before BIOFAR only 16 mysíd specíes had been re-

ported from the Faroese Fishery Territory. The BIOFAR

sampling increased the number of species to 34. For

each species the following information is given: the

valid name with author and publication year, synonyms,

reference to a good description, previous Faroese

records, the BIOFAR stations where it was found, area

descriptions, depth range, measured temperature range

or estimated temperature range of the near-bottom wa-

ter, the type of water mass in which the specimens were

caught, and short notes on the distribution and the depth

range of the species in the Atlantic Ocean.

Twenty-seven species have a hyperbenthic life style,

five are meso- or bathypelagic, and two are bentho-

pelagic. Six species are most often recorded from the

Faroe plateau or the tops of the banks (0-299 m), 16-18

species seem to be slope (300-999 m) species, and 10-12

species are mostly or only caught in deep water (> 1000

m). Eighteen species are mostly confined to water dom-

inated by «warm» Atlantic Water (> 7 °C), seven

species are mostly confined to water dominated by cold

bottom water of the Norwegian Sea (< 0 °C) or Arctic

Intermediate Water (1.5-3.5 °C), and nine species are

mainly found in well mixed water masses.
