13" cast iron dutch oven over a propane burner works well for me. One for the fish and seperate one for hushpuppies and fries. I am working to modify a grille into a fish cooker right now. Will still be using the dutch ovens, just incorporating the burners into a grille so I can close the lid and cover the pots. Can usually use the fish oil a couple times and the oil for hushpuppies and fries several times. I cook for the whole family usually once every week or two. Oh yeah, the thermometer is a must.
