Cook the rice according to the package directions.
Coat a 10" no-stick skillet with no-stick spray and place over medium-high heat until hot. Add the onions, peppers, carrots, celery, and scallions. Cook, stirring, for 2 minutes, or until the vegetables are bright in color. Transfer to a medium bowl.
To the skillet, add the cod, shrimp, wine or apple juice, soy sauce, garlic, curry powder, and salt. Cover and cook, stirring frequently, for 4 to 6 minutes, or until the fish and shrimp are opaque in the center. Check by inserting the tip of a sharp knife into the center of 1 cube and 1 shrimp.
Add the vegetables to the skillet. Toss to combine. Heat through. Serve over the rice.
