\n<\/span>Eqalugaq (polartorsk, Boreogadus saida) har en central rolle i arktiske marine \u00f8kosystemer. Enhver \u00e6ndring i polartorsk-populationens dynamik kan have kaskadevirkninger p\u00e5 dens rovdyr og de tjenester, den leverer til gr\u00f8nl\u00e6ndere, herunder rekreativt fiskeri og jagt, kommercielt fiskeri, \u00f8koturisme og kulturel v\u00e6rdi. Polartorsken er en kuldetilpasset art med en sn\u00e6ver termisk tolerance i det tidlige liv. Den er ogs\u00e5 meget f\u00f8lsom overfor havopvarmning, og vi ved at artsoverfloden er faldet i nogle regioner. F\u00e6notypisk og genetisk variabilitet er sammen med populationsstrukturen vigtige aspekter at overveje i polartorskens reaktion p\u00e5 klima\u00e6ndringer og b\u00f8r overvejes i forvaltningen af menneskelige aktiviteter, som forventes at p\u00e5virke arten i stigende grad. Uummannaq-fiskere fanger polartorsk som lokkemad og har rapporteret, at der findes to morfotyper: en hvid og en sort. I dette projekt \u00f8nsker vi at unders\u00f8ge de underliggende \u00e5rsager til disse to f\u00e6notyper. Vi vil forts\u00e6tte vores samarbejde med Uummannaq-fiskere om at indsamle pr\u00f8ver af polartorsk og udf\u00f8re laboratorieanalyser for at vurdere, om morfotyperne er forbundet med habitat, k\u00f8n, alder, fysiologisk tilstand, reproduktiv aktivitet eller genotype.<\/p>\n

Metoder til inklusion af samfundet:<\/strong>
\n<\/span>Projektet er baseret p\u00e5 vores l\u00f8bende samarbejde med Uummannaq fiskere, Uummannaq Polar Institute, Uummannaq fiskefabrikker, KNAPK og andre lokale partnere. Vi vil forts\u00e6tte med at formidle projektets relevante resultater, billeder og historier gennem lokale medier (radio, aviser), GINRs hjemmeside og sociale medier.<\/p>\n

Metoder til formidling til offentligheden:<\/strong>
\n<\/span>Vi planl\u00e6gger at producere en tegneserie i samarbejde med B\u00f8rnehjemmet i Uummannaq og Uummannaq Polar Institute, der viser det igangv\u00e6rende samarbejde mellem fiskere og forskere i Uummannaq. Tegnefilmproduktionen vil blive udf\u00f8rt under vores bes\u00f8g i Uummannaq i 2023 og involverer en kunstner, b\u00f8rn, fiskere, videnskabsm\u00e6nd og tolke.<\/p>\n
