Question

Can fish scale be eaten?

Answer 1

Scales:

1. The scales protect fishes from many invading pathogens and other organisms.
2. Normally, fish scales are avoided but they are consumed conventionally in many countries as snacks.
3. Fish scales contain collagen, but they should only be consumed after washing properly and cooking in the right way.
4. But many fishes contain mercury and other toxins or contaminants that may be present in the skin, so it is better to avoid the fish scales.
