What sicence is there behind the scientific claims of fermented fish oil? For instance Green Pastures Fermented Cod Liver Oil that many recommend claiming it isn't rancid like other fish oils.

Fermented Fish oil is different in a way that cod livers are fermented which helps in separating the fat soluble vitamins and beneficial oils to be separated from liver without damaging the fat soluble vitamins unlike regular fish oil.
Fermented Fish oil has the added benefits of being naturally rich in the fat-soluble vitamins D and A.

Fermentation usually gives many positive side-effects like more vitamins and is usually better digested by the body.
But the claim that oxidized omega-3 isn't helpful or more often demonized as something very unhealthy scrutinized in this paragraph:
"The acute effect of increasing doses of animal O3 is a reduction in arachidonic acid-derived inflammatory metabolites, increases in membrane permeability and anti-inflammatory molecules derived from EPA/DHA, as well as reduction in T-cell activation and antigenic stimulation. O3 also have direct effects: inhibition of LPS or lipopeptide-stimulated COX2 expression and LPS-induced NFkB activation (24,25). Interestingly, there is evidence that the anti-inflammatory effects seen for O3 are dependent on their oxidation. Oxidized EPA, but not unoxidized EPA, inhibits NFkB activation and expression of inflammatory molecules in a PPARa dependent manner, as well as chemotaxis (26,27,28). Oxidized, but not unoxidized DHA, inhibits polychlorinated biphenyl-induced NFkB activation and MCP-1 expression, effects probably mediated by its oxidation products (A4/J4 neuroprostanes) (29). Thus, it seems that contrary to what is believed, oxidation of O3 PUFA is necessary to mediate their beneficial biological effects."
So oxidized Omega-3 is not only good for you but a must for its good properties to be beneficial if this study is to be believed.
