This thesis offers a comprehensive analysis of how climate change affects fisheries, presenting empirical evidence and methodological innovations that contribute to the development of adaptive management strategies. In particular, it seeks to understand how warming waters, distributional species shifts, and extreme weather events are disrupting fishery dynamics and undermining the stability of fishers’ livelihoods. Different facets of production are examined such as expected output, variance in harvest, and production risk. Using the lobster (Homarus americanus) fishery in Atlantic Canada as a case study and advanced econometric and statistical methods, this research provides insights that are applicable to other fisheries, particularly those with input-controlled management systems. Denne oppgaven tilbyr en omfattende analyse av hvordan klimaendringer påvirker fiskeriene, og presenterer empiriske bevis og metodiske innovasjoner som bidrar til utviklingen av adaptive forvaltningsstrategier. Spesielt søker den å forstå hvordan oppvarmende vann, skiftende arter i utbredelsen og ekstreme værhendelser forstyrrer fiskeridynamikken og undergraver stabiliteten til fiskernes levebrød. Ulike fasetter av produksjonen blir undersøkt som forventet produksjon, variasjon i høsting og produksjonsrisiko. Ved å bruke hummerfisket (Homarus americanus) i Atlanterhavet Canada som en casestudie og avanserte økonometriske og statistiske metoder, gir denne forskningen innsikt som er anvendelig for andre fiskerier, spesielt de med input-kontrollerte forvaltningssystemer.
