Skip the newspaper and wrap your fish in grape leaves that have been soaked in water for a bit.
Using an oil-soaked paper towel and a pair of tongs, liberally lube up your grill's grate to keep fish from sticking.
Better yet, lay down a layer of sliced lemons or onion and cook your fish on top of them for a non-stick flavor-infusion.
When you go to flip your fish, put one spatula on top and slide another underneath to keep your fillets from falling apart.
Get a fish basket. There are all kind of shapes and styles out there, but the flat, rectangular ones are the most versatile.
