### How Is Praziquantel Administered to Fish?

1. **Oral Administration:**.

Praziquantel can be mixed with fish food. When administered this way, care must be taken to ensure all fish consume the medicated food to achieve uniform treatment.

2. **Bath Treatment:**.

In a bath treatment, Praziquantel is dissolved in water. The fish are then placed into this medicated water for a specified period. This method is typically used for treating external parasites.

### Effectiveness of Praziquantel for Fish.
