Thaw fish, if frozen. Rinse fish and pat dry with paper towels. Cut fish crosswise into 3/4-inch slices. Place fish in a single layer in a greased shallow baking pan. Combine olive oil, cumin, and garlic powder. Brush over fish. Bake in a 450 degree F oven for 4 to 6 minutes or until fish begins to flake when tested with a fork.
Meanwhile, in a medium bowl stir together mayonnaise and lime juice. Add cabbage; toss to coat. Spoon some of the coleslaw mixture into each taco shell; add fish slices and top with Mango Salsa.
