1. Always start with fresh fish if possible. You will have a better grilling experience. Previously frozen fish will also work; it's just harder to work with. Plan on 6-8 ounces per person for fillets and 8-12 ounces per person when buying whole fish.

2. When grilling directly on the grill it is best to use a firm fleshed fish like grouper, marlin, salmon or tuna. A special fish and vegetable grid will make grilling easier. The finer mesh will help keep your food from falling through. You may even want to use a wire grill basket, especially for those more delicate fillets. This way you can turn your fish over without worrying about it breaking apart. You can even stick lemon slices between the fish and basket, if you wish.

3. Always make sure your grill is clean and well-lubricated with oil to prevent your fish from sticking. Fish breaks apart easily. If it sticks to your grill, you will have nothing but little pieces to serve. I like to saturate a paper towel with cooking oil and wipe down my grill before putting my food on. I haven't tried it yet, but PAM also has a cooking spray made just for grilling.
