All fish bones are bent. Is eating such fish harmful to human body?

If there is nothing wrong with the fish's body surface and body, it will not affect it. Many fish will become deformed. There are many reasons, some are stuck somewhere during the growing period, and some are due to fetal hypoplasia. I've seen a lot of S fish and gourd fish, all of which were caught in fishing nets during the growing period. Skeletal deformity does not affect meat quality.
