Professor Ivar Rønnestad har en bakgrunn innen human og komparativ fysiologi. Tidlig i sin karriere arbeidet han med termoregulering og respiratoriske tilpasninger hos dykkere, med fokus på fysiologiske mekanismer som muliggjør at mennesker kan fungere i ekstreme miljøer, som ved dykking ned til 360 meters dybde. Rønnestad var involvert i forsøk som førte til utviklingen av Norges første pustgassesystem for dypdykking (OBS).

Overgangen til fiskefysiologi gjorde det mulig for Rønnestad å anvende sin kunnskap innen komparativ fysiologi, metabolsk regulering og adaptive mekanismer for å forbedre kunnskapen om fiskens utvikling, fôringsbiologi, vekst og miljøtilpasninger. Hans ekspertise innen disse områdene har bidratt til betydelige fremskritt i forståelsen av fiskens ernæringsfysiologi.

Siden 1988 har hans primære forskningsinteresse vært ernærings- og fordøyelsesfysiologi hos teleoster. For tiden fokuserer han på fordøyelse og appetittregulering, spesielt tarm-hjerne-aksen, og hvordan denne relaterer seg til vekst og energiomsetning. De siste årene har de fleste studiene på atlantisk laks, men Rønnestad har bred erfaring med andre akvakulturarter.

Professor Rønnestads forskning bidrar til grunnleggende vitenskap og praktiske forbedringer i akvakultur innen følgende områder:

Fordøyelsesfysiologi og fôropptak hos fiskelarver: Hans tidlige arbeid på teleoster utforsket fordøyelsesprosesser hos fiskelarver, inkludert fordøyelse, absorpsjon og den funksjonelle utviklingen av fordøyelsessystemer fra første fôring til metamorfose. Disse studiene har som mål å forbedre fôringsprotokoller og øke kvalitet og overlevelse i akvakultur.

Fiskens vekst og metabolisme: Hans nåværende forskning legger vekt på de molekylære og fysiologiske mekanismene som ligger til grunn for appetitt, fordøyelse, fôrinntak og vekst hos fisk. Et nøkkelområde er forståelsen av appetittkontroll og signalerveier i tarm-hjerne-aksen, spesielt hvordan tarm-avledede signaler som hormoner kommuniserer med hjernen for å regulere sult og metthet. Denne forskningen er viktig for å optimalisere fôrinntak, forbedre vekstrater og fremme bærekraft i akvakultur.

Melanokortinsystemet og appetittkontroll: Et viktig aspekt av hans arbeid omhandler studiet av nevropeptider i melanokortinsystemet, som er involvert i appetittkontroll som skjer i hypothalamus. Hans forskningsgruppe har kartlagt sentrale nevropeptider hos fisk som atlantisk laks, og knyttet disse til fôringsadferd og energihomeostase. Denne forskningen bidrar til mer effektiv akvakultur ved å optimalisere vekst, forbedre fôrutnyttelse og redusere utslipp fra anlegg.

Akvakultur og bærekraft Rønnestad er også involvert i prosjekter som har som mål å forbedre bærekraften i akvakultur, med fokus på bruk av alternative fôringredienser (f.eks. erstatning for fiskemel) og å undersøke effekten av miljøendringer som global oppvarming på fiskens fysiologi, veksty og velferd.

Gassboblesykdom hos fisk: Med utgangspunkt i hans tidlige arbeid med dykkefysiologi, har Rønnestad deltatt i nyere forskning på gassboblesykdom hos atlantisk laks. Denne tilstanden, relatert til gassovermetning, speiler utfordringer som man arbeider med innen human dykkefysiologi og er viktig for å forbedre operasjonelle prosedyrer for å redusere dødelighet og velferdsproblemer i akvakultur.

Samlet sett bidrar Professor Rønnestads arbeid både til den vitenskapelige forståelsen av fiskefysiologi og til utviklingen av praktiske løsninger for å forbedre effektiviteten og bærekraften i akvakultur.

Ivar Rønnestad underviser i fagene BIO104 (Komparativ fysiologi) og BIO 291 (Fiskebiologi II- Fysiologi) i tillegg til veiledning av postdoktor, PhD og Master studenter. Han leder EcelAQUA Sommerskole som er et samarbeide mellom Universitetet i Bergen, NORCE og syv ulike universiteter og forskningsinstitutt i Japan.
