Sharkey's Barbequed Trout

In a medium bowl, mix together soy sauce, vegetable oil, dried rosemary, ketchup and lemon juice. Set marinade aside.

Place rainbow trout in a medium baking dish, and pour marinade over the fish. Refrigerate for approximately 1 hour, turning trout once.

Preheat an outdoor grill for medium high heat and lightly oil grate. Drain excess marinade from fish, and transfer to a small saucepan. Bring marinade to a boil, and than remove from heat.

Place trout on the prepared grill. Baste fish with remaining marinade sauce while grilling. Cook approximately 5 minutes on each side, or until tender and easily flaked.
