How to Prevent Fish From Sticking to Grill
To prevent fish from sticking to the grill, spray the cold grill grates with cooking spray or brush lightly with vegetable oil. To avoid flare-ups, don't use cooking spray or use oil directly over flames.
If using wooden skewers, soak skewers in water for 30 min. before using to assemble kabobs to prevent them from burning on the grill.
