Forskningsinteresser
Min forskning er relativt bredt anlagt innenfor havbruk, og omfatter ulike sider ved vannmiljø og hvordan det påvirker oppdrettsorganismen. Jeg har fokusert på fôr og fôring av fisk i oppdrett, inkludert fôr tilpasset lukkede produksjonssystemer (RAS) og fôring av fisk i kommersiell skala i sjø. Jeg har jobbet levendelagring av villfanget fisk (levendefangst og lagring av torsk) inkludert fôr og fôring av denne. I mer enn 15 år har jeg også vært involvert i forskning på effekter av oppdrett på miljø, særlig villfisk rundt anlegg. Dette er et område som ofte kalles for sameksistens, da særlig mellom fiskeri og havbruk.
Undervisning
Jeg har undervisningsansvar for fiskeernæring (BIO 2602). Dette er et kurs som inngår i studieplanen til Akvamedisin og som ellers kan tas som valgfritt emne av studenter på Fiskeri og Havbruksvitenskap, samt andre biologi studenter.
I tillegg underviser jeg på andre kurs ved UiT, som Fish physiology (BIO 2404), Oppdrettsteknologi (FSK 2010), og Semester i bærekraftig Havbruk (FSK 2030).
