    • Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability 

      Strople, Leah Catherine; Vieweg, Ireen; Yadetie, Fekadu; Odei, Derrick Kwame; Thorsen, Anders; Karlsen, Odd André; Goksøyr, Anders; Sørensen, Lisbet; Sarno, Antonio; Hansen, Bjørn Henrik; Frantzen, marianne; Hansen, Øyvind J; Puvanendran, Velmurugu; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-03)
      Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key arctic fish, may be at risk for crude oil exposure during this potentially sensitive life stage. Additionally, this species experiences lower food availability during their spawning ...

    • Sustainable Development of Aquaculture on the Volta Lake. A case study of the Asuogyaman District in the Eastern Region of Ghana 

      Odei, Derrick Kwame (Master thesis; Mastergradsoppgave, 2015-05-15)
      Aquaculture in Ghana has been in existence for over 50years. However, it has been less productive despite its high potential for commercial and other scales of production. The Volta Lake presents a huge available resource for the success of cage aquaculture in the country. The cage system of production was introduced in 2001 according to Kasam (2014). This system of aquaculture production even ...

    • Transcriptome sequencing and histology reveal dosage compensation in the liver of triploid pre-smolt Atlantic salmon 

      Odei, Derrick Kwame; Hagen, Ørjan; Peruzzi, Stefano; Falk-Petersen, Inger-Britt; Fernandes, Jorge Manuel de Oliveira (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-08)
      Triploid Atlantic salmon (<i>Salmo salar</i> L.) is seen as one of the best solutions to solve key issues in the salmon farming industry, such as the impact of escapees on wild stocks and pre-harvest sexual maturation. However, the effects of triploidy on salmon smoltification are poorly understood at the molecular level, even though smoltification is a very sensitive period that has a major influence ...
