Projektleder:<\/strong> Julius Nielsen, forsker ved Gr\u00f8nlands Naturinstitut
\n\u00d8vrige deltagere:<\/strong>

Projektets baggrund, form\u00e5l og forskningssp\u00f8rgsm\u00e5l:<\/strong>
\nPukkellaks i Gr\u00f8nland er en potentiel invasis h\u00f8jrisiko-art, der er naturligt hjemmeh\u00f8rende i det nordlige Stillehav.
\nI Atlanten stammer pukkellaks fra russiske uds\u00e6tninger ved Kola-halv\u00f8en og optr\u00e5dte for f\u00f8rste gang i store m\u00e6ngder i blandt andet norske, irske, og islandske elve i 2017. I sensommeren 2019 blev pukkellaks i stort omfang rapporteret til Naturinstituttet fra hele Gr\u00f8nland inklusiv ved Kapisillit-elven i bunden af Nuuk Fjorden, der ogs\u00e5 huser Gr\u00f8nlands eneste bestand af Atlanterhavslaks. Atlanterhavslaksen i Kapisillit er Gr\u00f8nlands eneste r\u00f8dlistede fisk og bestanden er i tilbagegang.<\/p>\n

Form\u00e5let med dette 2-\u00e5rige projekt er at unders\u00f8ge tilstedev\u00e6relsen af pukkellaks i Kapisillit-elven i 2020 og 2021 ved brug af eDNA og elfiskeri. De konkrete forskningssp\u00f8rgsm\u00e5l som projektet s\u00f8ger at besvare er:
\n1. Er der pukkellaks tilstede i Kapisillit-elven i den potentielle gydeperiode (juli-september)?
\n2. Hvis pukkellaks er tilstede i elven, overlapper de i tid og rum?
\n3. Har pukkellaks haft succesfulde gydninger i Kapisillit-elven?
\n4. Er bestanden af atlanterhavslaks faldende eller stigende i forhold til estimater fra 2017 og 2018?<\/p>\n

At f\u00e5 besvaret disse sp\u00f8rgsm\u00e5l vil give forvaltere mulighed for at evaluere eventuelle pr\u00e6ventive initiativer s\u00e5fremt det \u00f8nskes at beskytte Gr\u00f8nlands eneste laksebestand imod den potentielt invasive pukkellaks.<\/p>\n

Metoder for inklusion af samfundet:<\/strong>
\nOpm\u00e6rksomheden omkring pukkellaks startede i august 2019 da Naturinstituttet via en efterlysning p\u00e5 Facebook modtog op mod 90 observationer af pukkellaks fra over hele Gr\u00f8nland.
\nEn lignende efterlysning vil blive foretaget i senommer 2020 og 2021, hvor samfundet derved vil blive inddraget i indsamlingen af viden om pukkellaksens udbredelse.<\/p>\n

Metoder for formidling overfor samfundet:<\/strong>
\nResultater for projektet vil blive formidlet via Naturinstituttets sociale medier (Facebook), Naturinstituttets nystartede podcast samt til ‘Natur om Torsdagen’ i Nuuk, efter\u00e5ret 2020 og 2021.
\nProjektets resultater vil ogs\u00e5 blive formidlet i Suluk efter aftale.<\/p>\n

Projektets start- og afslutningstidspunkt:<\/strong>
\nJuni 2020 – December 2021<\/p>\n
