That spicy tuna roll you order at your favorite sushi restaurant may not be tuna at all. And the yellowtail? It could be something else entirely. In fact, according to a new study, as much as half of nine types of fish sold in Los Angeles-area sushi restaurants may be mislabeled, despite tougher laws and increased media scrutiny in recent years.
