We hunted with the Inuit up above Hutson bay. And they eat the hell out of lake trout and char blood veins ( large blood sack that runs down the inside of the backbone.) They would suck it up like big thick spaghetti noodles. And they ate some raw caribou as we broke them down to pack out. They offered us the gall bladder and I declined as they did not take a bite of it themselves. I refused and they laughed out loud, and said if you take bite of this, you never get “ hard” again. I’ve also eaten raw hamburger with salt pepper and onion slices, made sandwich’s years ago. My dad ate them regularly.
