Do Fish Have Saliva?
A fish does eat with its mouth and has many organs that are similar to a human so your question is logical.
The buccal cavity of the mouth secretes mucus to aid in the swallowing of food, but there are no salivary glands. This mucus is a only a lubricant, it contains no digestive enzymes like mammalian saliva. So no food is chemically altered in the mouth.
