"West Coasters famously do this with whole Salmon in the dishwasher. Comes out perfectly, no cleanup. "

Wha...?!?

Wow... that's pretty cool.

I simply cook cleand fish over open fire by running a stick through the gills and out the mouth I cook fish with a variety of spices lots of times just oliveoil and salt and pepper. Dont forget to reposition fish often fish cook fast. I have cooked 4 fish at the same time this way on the same (SPIT)stick. and they came out evenly cooked and delisous and I still had my cook pot clean for brewing coco or what have you.
