1 lb. fresh or frozen perch fillets
1/2 c. pineapple juice (I use the juice from canned pineapple packed in its own juice)
1 tbsp. lime juice (I use lemon juice)
2 tsp. Worcestershire sauce
1/2 tsp. salt

Thaw frozen fish cut into 4 portions. Place in shallow dish. Combine last 4 ingredients, pour over fish. Marinate in refrigerator 1 hour, turning once. Reserving marinade, place fish on greased rack of broiler pan. Broil 4 inches from heat until fish flakes easily, 10-12 minutes (it will not take as long to broil if fillets are thin). Brush occasionally with marinade. Heat remaining marinade and spoon over fish before serving.
