Should I drink sardine juice instead of dumping it down the drain?

I eat sardines that are canned in water, not oil, because I care about my polyunsaturated fatty acid ratio. They're very unappetizing but from my inexpert skimming, they seem like one of the best options in terms of health. But I only eat most of the flesh incidentally, with the main objective being the fat. This is why I always buy fish that is unskinned, and in fact I would buy cans of fish skin if it were easy.

So on this basis, is it worth it for me to just go ahead and choke down the sardine water as well? ...or perhaps instead? It is visibly fatty.
