Can you eat the flower of the mandarin fish?
Under normal circumstances, mandarin fish (guìyúhuā) is edible and safe to consume as long as it is eaten in moderation. The details are as follows:

Mandarin fish has a tender texture and is easy to digest. It is rich in high-quality protein, various vitamins, and essential minerals such as calcium and phosphorus. Its nutrients are easily absorbed and utilized by the body, making it suitable for most people. As long as the fish comes from a safe source and is thoroughly cooked, any potential bacteria or parasites can be eliminated, minimizing health risks. Whether steamed, boiled in soup, or pan-fried, mandarin fish retains its nutritional value and delicious flavor, making it a common and healthy ingredient in daily meals.
When purchasing, choose fresh or well-preserved frozen mandarin fish, and avoid spoiled or low-quality products. Rinse the fish thoroughly with clean water before cooking to remove surface impurities, and ensure it is fully cooked. If gastrointestinal discomfort occurs after consumption, stop eating it immediately and monitor symptoms. For storage, fresh mandarin fish should be consumed promptly, while frozen fish should be sealed properly to prevent odor transfer and maintain freshness and hygiene.
