GJENNOMFØRING

Toktet vart stort sett gjennomfØrt som i tidlegare år med unnatak av at tidlegare tokt har vorte gjennomfØrte også med innsats av ein trålar. Dette gjorde at innsatsen i

1987

(ant. stasjonar,

₁₃₃₎

var den minste i heile tidsserien. På 9runn av dårleg vær vart også dekninga redusert og starta 42 vart ikkje dekt i det heile.

Botntrålsurveyet vart gjennomfØrt saman med fleirbestandssureveyet.

Trålforsøk vart gjennomfØrde både under og etter botntrålsurveyet.

RESULTAT

Resultata frå toktet er viste i fylgjande tabeller og fugurar.

Hydrografi er presentert i rapporten frå fleirbestandstoktet.
