In a bowl, combine crab meat, bread crumbs, egg, mayonnaise, parsley, Old Bay seasoning, black pepper, lemon juice, and bell pepper. Mix gently to avoid breaking the crab meat.
Heat vegetable oil in a deep fryer or large pot to 350°F. Fry the crab balls in batches until golden and crispy, about 4-5 minutes. Drain on paper towels.
