Studies

Aim: To investigate whether Atlantic cod that feed close to aquatic breeding facilities are affected by chlorpyrifos-methyl. Feeding experiment with chlorpyrifos-methyl, an organophosphorous pesticide detected in plant based salmon feed. Based on previous experiments using salmon.

Doses: 0, 0.5, 5.0, 25 mg/kg) chlorpyrifos-methyl. Duration: 30 days Set-up: Three tanks per treatment (12 in total)

Samples include: Liver, plasma, bile, brain. Analysis include:

• Have RNAseq and metabolomics from 36 ...

Aim: *To investigate effects on lipid metabolism in Atlantic cod ( Gadus morhua) mediated by peroxisome proliferator-activated receptors (Ppars) by in vivo exposure to two mammalian PPAR agonists.

This study involves all data gathered from the Kollevåg study - studying environmental pollution at a capped waste disposal site in Kollevåg, Askøy.

Cod were caged in Kollevåg (Stations 1, 2 and 3 - from inner to outer parts) and at a reference location (Ref station) for a period of six weeks, from 2nd September 2016, to 17-18th October 2016.
