• Designing a species-specific method, based on analysis of eDNA, for detection of lesser weever fish, and testing it at chosen locations along the coastline of Agder, Southern Norway 

  Sjøstrøm, Jimmi (Master thesis, 2023)

  Temperature is largely influencing species dispersion, and when the temperature conditions within an area are changing, species populations often respond by moving to other, more suitable areas. Such behavior has often ...

• Analyzing the reliability of citizen science information using Pacific oysters as a model system 

  Fawad,Amna (Master thesis, 2023)

  Det biologiske mangfolds krisen har ført til at mange arter har blitt utryddet de siste 20 årene; En av årsakene til dette er økende nærvær av fremmede arter. Mange av disse artene er uidentifiserte, noe som gjør det ...

• Behavioral reactions to H2S in farmed Salmon 

  Markhus, Lars Martin (Master thesis, 2023)

  I resirkulerende akvakulturanlegg kan dannelse av hydrogensulfid (H2S) føre til akutt massedød av laks. Det er begrenset med kunnskap om hvordan fisk reagerer på H2S ved lave konsentrasjoner. Automatisk tolking av adferd ...
