Your choice in fish marinades is limitless: there are diverse recipes of them. Additionally, each cuisine has its own traditions in cooking fish, therefore, there are even more differences in preparation of fish marinades. In the majority of cases, the major component of fish marinades is white wine. As far as the herbs are concerned, their choice depends on your taste: for instance, if you do not like the aroma of thyme, substitute it with the herb you like or, at least, leave it out. Then, there are special sets of herbs and spices selected specially for fish marinades, available at our stores, perhaps, one of them will satisfy your preferences.   

Here is a recipe of the basic fish marinade, appropriate for each seafood type, which you are going to grill.

You can experiment on the preparation of fish marinades as much as your fantasy allows. Fish goes well with fruit fish marinades, cranberry, pineapple, or any citrus combinations. Milk can be used as the basis for fish marinades; it will not add any flavor, though will considerably soften the fish. Surprisingly, beer is considered a universal marinade and is a good flavoring to any fish.
