Sea bass... raw?

[Kookaburra]

Sea bass contains little fat (only 2%), so you cannot keep it in the fridge for long (as opposed to salmon and tuna).

So the less fat a fish has, the shorter it can last in the fridge? Why is it so?

[RRM]

Its just a general observation that does not hold true for all fish species.
Mackerel, for example, contains quite some fat, and yet you cannot keep it for more than 2 days.
Thats because other factors are at play as well, such as the level of amines.
But about the fat; it acts as a kind of protective layer.
