Last year, I bought some HY-VEE brand veggie oil on sale and when you cooked with it, it reeked so bad that I mixed about 1 pint of oil from all of the sardines I had eaten that summer to about 1/2 gallon of the veg oil. It worked as well as anything else I used.
You could also mix procoon with it. Trappnman has the stuff if you are interested.
One thing with shellfish oil is that if you smell the stuff full strength, your mouth will taste like blood for about an hour. At least that is what happens to me.
