Press or finely chop the 4 garlic cloves. Mix with the juice from the 2 limes, the dry white wine, olive oil, Italian herbs, and fish seasoning. Season to taste with salt and pepper.
Rub the marinade inside and outside each trout. Place in a freezer bag or flat dish, pour in any remaining marinade, and refrigerate for 3 to 4 hours.
Place the trout in fish grill tongs and grill over medium-high heat for 5 to 7 minutes on each side.
Serve with white bread or baked potatoes and a crunchy salad.
